commit 1cf6022bd9 upstream.
Quoth the man page:
```
If the tracee was restarted by PTRACE_SYSCALL or PTRACE_SYSEMU, the
tracee enters syscall-enter-stop just prior to entering any system
call (which will not be executed if the restart was using
PTRACE_SYSEMU, regardless of any change made to registers at this
point or how the tracee is restarted after this stop).
```
The parenthetical comment is currently true on x86 and powerpc,
but not currently true on arm64. arm64 re-checks the _TIF_SYSCALL_EMU
flag after the syscall entry ptrace stop. However, at this point,
it reflects which method was used to re-start the syscall
at the entry stop, rather than the method that was used to reach it.
Fix that by recording the original flag before performing the ptrace
stop, bringing the behavior in line with documentation and x86/powerpc.

We can avoid this by bailing out if pmd_alloc() fails, as we do earlier
in the function if pud_alloc() fails.

commit 0225fd5e0a upstream.
In the unlikely event that a 32bit vcpu traps into the hypervisor
on an instruction that is located right at the end of the 32bit
range, the emulation of that instruction is going to increment
PC past the 32bit range. This isn't great, as userspace can then
observe this value and get a bit confused.
Conversly, userspace can do things like (in the context of a 64bit
guest that is capable of 32bit EL0) setting PSTATE to AArch64-EL0,
set PC to a 64bit value, change PSTATE to AArch32-USR, and observe
that PC hasn't been truncated. More confusion.
Fix both by:
- truncating PC increments for 32bit guests
- sanitizing all 32bit regs every time a core reg is changed by
userspace, and that PSTATE indicates a 32bit mode.

commit 1578e5d031 upstream.
On arm64 linux gcc uses -fasynchronous-unwind-tables -funwind-tables
by default since gcc-8, so now the de facto platform ABI is to allow
unwinding from async signal handlers.
However on bare metal targets (aarch64-none-elf), and on old gcc,
async and sync unwind tables are not enabled by default to avoid
runtime memory costs.
This means if linux is built with a baremetal toolchain the vdso.so
may not have unwind tables which breaks the gcc platform ABI guarantee
in userspace.
Add -fasynchronous-unwind-tables explicitly to the vgettimeofday.o
cflags to address the ABI change.

[ Upstream commit c9a4ef6645 ]
In assembly, many instances of __emit_inst(x) expand to a directive. In
a few places __emit_inst(x) is used as an assembler macro argument. For
example, in arch/arm64/kvm/hyp/entry.S
ALTERNATIVE(nop, SET_PSTATE_PAN(1), ARM64_HAS_PAN, CONFIG_ARM64_PAN)
expands to the following by the C preprocessor:
alternative_insn nop, .inst (0xd500401f | ((0) << 16 | (4) << 5) | ((!!1) << 8)), 4, 1
Both comma and space are separators, with an exception that content
inside a pair of parentheses/quotes is not split, so the clang
integrated assembler splits the arguments to:
nop, .inst, (0xd500401f | ((0) << 16 | (4) << 5) | ((!!1) << 8)), 4, 1
GNU as preprocesses the input with do_scrub_chars(). Its arm64 backend
(along with many other non-x86 backends) sees:
alternative_insn nop,.inst(0xd500401f|((0)<<16|(4)<<5)|((!!1)<<8)),4,1
# .inst(...) is parsed as one argument
while its x86 backend sees:
alternative_insn nop,.inst (0xd500401f|((0)<<16|(4)<<5)|((!!1)<<8)),4,1
# The extra space before '(' makes the whole .inst (...) parsed as two arguments
The non-x86 backend's behavior is considered unintentional
(https://sourceware.org/bugzilla/show_bug.cgi?id=25750).
So drop the space separator inside `.inst (...)` to make the clang
integrated assembler work.

Systems affected by Neoverse-N1 #1542419 support DIC so do not need to
perform icache maintenance once new instructions are cleaned to the PoU.
For the errata workaround, the kernel hides DIC from user-space, so that
the unnecessary cache maintenance can be trapped by firmware.
To reduce the number of traps, produce a fake IminLine value based on

[ Upstream commit 46f94c7818 ]
If the mv88e6xxx DSA driver is built as a module, it causes the
ethernet driver to re-probe when it's loaded. This in turn causes
the gigabit PHY to be momentarily reset and reprogrammed. However,
we attempt to reprogram the PHY immediately after deasserting reset,
and the PHY ignores the writes.
This results in the PHY operating in the wrong mode, and the copper
link states down.
Set a reset deassert delay of 10ms for the gigabit PHY to avoid this.

[ Upstream commit f9f711efd4 ]
If the kernel configuration option CONFIG_PCIE_DW_PLAT_HOST is enabled
then this can cause the kernel to incorrectly probe the generic
designware PCIe platform driver instead of the Tegra194 designware PCIe
driver. This causes a boot failure on Tegra194 because the necessary
configuration to access the hardware is not performed.
The order in which the compatible strings are populated in Device-Tree
is not relevant in this case, because the kernel will attempt to probe
the device as soon as a driver is loaded and if the generic designware
PCIe driver is loaded first, then this driver will be probed first.
Therefore, to fix this problem, remove the "snps,dw-pcie" string from
the compatible string as we never want this driver to be probe on
Tegra194.

commit b8fdef311a upstream.
Compilers with branch protection support can be configured to enable it by
default, it is likely that distributions will do this as part of deploying
branch protection system wide. As well as the slight overhead from having
some extra NOPs for unused branch protection features this can cause more
serious problems when the kernel is providing pointer authentication to
userspace but not built for pointer authentication itself. In that case our
switching of keys for userspace can affect the kernel unexpectedly, causing
pointer authentication instructions in the kernel to corrupt addresses.
To ensure that we get consistent and reliable behaviour always explicitly
initialise the branch protection mode, ensuring that the kernel is built
the same way regardless of the compiler defaults.
[This is a reworked version of b8fdef311a ("arm64: Always
force a branch protection mode when the compiler has one") for backport.
Kernels prior to 74afda4016 ("arm64: compile the kernel with ptrauth
return address signing") don't have any Makefile machinery for forcing
on pointer auth but still have issues if the compiler defaults it on so
need this reworked version. -- broonie]

commit fc2266011a upstream.
For thumb instructions, call_undef_hook() in traps.c first reads a u16,
and if the u16 indicates a T32 instruction (u16 >= 0xe800), a second
u16 is read, which then makes up the the lower half-word of a T32
instruction. For T16 instructions, the second u16 is not read,
which makes the resulting u32 opcode always have the upper half set to
0.
However, having the upper half of instr_mask in the undef_hook set to 0
masks out the upper half of all thumb instructions - both T16 and T32.
This results in trapped T32 instructions with the lower half-word equal
to the T16 encoding of setend (b650) being matched, even though the upper
half-word is not 0000 and thus indicates a T32 opcode.
An example of such a T32 instruction is eaa0b650, which should raise a
SIGILL since T32 instructions with an eaa prefix are unallocated as per
Arm ARM, but instead works as a SETEND because the second half-word is set
to b650.
This patch fixes the issue by extending instr_mask to include the
upper u32 half, which will still match T16 instructions where the upper
half is 0, but not T32 instructions.

enable delay on both Rx and Tx so the interface mode used must
be PHY_INTERFACE_MODE_RGMII_ID.
Since commit 1b3047b520 ("net: phy: realtek: add support for
configuring the RX delay on RTL8211F") the Realtek 8211F PHY driver
has control over the RGMII RX delay and it is disabling it for
RGMII_TXID. The LS1043ARDB uses two such PHYs in RGMII_ID mode but
in the device tree the mode was described as "rgmii_txid".
This issue was not apparent at the time as the PHY driver took the
same action for RGMII_TXID and RGMII_ID back then but it became
visible (RX no longer working) after the above patch.
Changing the phy-connection-type to "rgmii-id" to address the issue.

Currently hsio root clock is always on, which should be handled
by hsiomix power domain driver but there is problem on doing that,
see commit 5aaceda10a ("MLK-23671-02 arm64: dts: imx8mp: Add the
rpm-always-on flag for hsiomix domain"):
"The hsiomix power domain need to be runtime always-on to maintain USB's
wakeup ability. As this domain need to be boot on by default, no one
will call the power on callback during system boot up, the clock
enable/disable will mismatch, so remove the clocks from this domain.
the necessary clocks will be handled in TF-A."
There is one clock(AXI_DIV) shared between hsiomix and USB, with
rpm-always-on property added, like above commit description, power
domain driver will not do enable/disable and think it's always on, but
it can be disabled by USB driver, afterwards if power domain driver does
hsiomix register access, system will hang because the required clock was
disabled.
Now with above commit and change in TF-A, those clocks are not
controlled by Linux for power domain operations, but user driver(i.e. USB
and PCIE) has to handle it.

The workaround is:
As the reset state of AUDIOMIX_CLKEN0[SDMA2] is enabled,
we just need to keep it on as reset state, don't touch it
in kernel, then every thing is same as before.
So for sdma node, it only need to care about AHB and IPG clock,

commit f50b7daccc upstream.
On a system configured to trigger a crash_kexec() reboot, when only one CPU
is online and another CPU panics while starting-up, crash_smp_send_stop()
will fail to send any STOP message to the other already online core,
resulting in fail to freeze and registers not properly saved.
Moreover even if the proper messages are sent (case CPUs > 2)
it will similarly fail to account for the booting CPU when executing
the final stop wait-loop, so potentially resulting in some CPU not
been waited for shutdown before rebooting.
A tangible effect of this behaviour can be observed when, after a panic
with kexec enabled and loaded, on the following reboot triggered by kexec,
the cpu that could not be successfully stopped fails to come back online:

If this bit is set to '1' operating in host mode, the core keeps the
UTMI/ULPI PHY on the first port in a non-suspended state whenever the
other non-SuperSpeed ports are not in a suspended state. This feature is
useful because it saves power by suspending UTMI/ULPI when SuperSpeed
only is active, and it helps resolve when the PHY does not transmit a
host resume unless it is placed in suspend state. This bit must be

(cherry picked from commit 7220fa2e1a02e471f5d3276601709f3df372ee63)
vabits_actual variable on arm64 indicates the actual VA space size,
and allows a single binary to support both 48-bit and 52-bit VA
spaces.
If the ARMv8.2-LVA optional feature is present, and we are running
with a 64KB page size; then it is possible to use 52-bits of address
space for both userspace and kernel addresses. However, any kernel
binary that supports 52-bit must also be able to fall back to 48-bit
at early boot time if the hardware feature is not present.
Since TCR_EL1.T1SZ indicates the size offset of the memory region
addressed by TTBR1_EL1 (and hence can be used for determining the
vabits_actual value) it makes more sense to export the same in
vmcoreinfo rather than vabits_actual variable, as the name of the
variable can change in future kernel versions, but the architectural
constructs like TCR_EL1.T1SZ can be used better to indicate intended
specific fields to user-space.
User-space utilities like makedumpfile and crash-utility, need to
read/write this value from/to vmcoreinfo for determining if a virtual
address lies in the linear map range.
The user-space computation for determining whether an address lies in
the linear map range is the same as we have in kernel-space:
#define __is_lm_address(addr) (!(((u64)addr) & BIT(vabits_actual - 1)))
I have sent out user-space patches for makedumpfile and crash-utility
to add features for obtaining vabits_actual value from TCR_EL1.T1SZ (see
[0] and [1]).
Akashi reported that he was able to use this patchset and the user-space
changes to get user-space working fine with the 52-bit kernel VA
changes (see [2]).

This enables monitoring of link status and AN. It should also physically
enable SGMII AN with the VSC8514 PHY, but in practice that is still
hardcoded as "on" in the PHY driver, at the moment. So since Felix
actually disables SGMII AN when this DT property is absent, this would
result in an in-band AN mismatch between the MAC and the PHY. So this
property is required for the moment for this MAC/PHY combination.

This reverts commit 841edb9867.
There are 2 separate issues with interrupts on the LS1028A-RDB board:
1. The GPIO1_DAT25 interrupt line is shared, so there is a real risk of
race conditions if used in edge-triggered mode, as we currently do.
This can be illustrated in the following setup:
- Take 2 LS1028A-RDB boards
- Connect swp0 to swp0, swp1 to swp1, swp2 to swp2
- Plug/unplug the power to board 2, 10 times in a row. This will make
the PHYs lose link simultaneously.
- Notice that at one point, the net devices on board 1 remain in a
state where not all the links are down (visible in "ip link"):
5: swp0: <BROADCAST,MULTICAST,UP> mtu 1468 qdisc pfifo_fast master br0 state UP mode DEFAULT group default qlen 1000
link/ether be:97:36:d3:3d:70 brd ff:ff:ff:ff:ff:ff
6: swp1: <BROADCAST,MULTICAST,UP> mtu 1468 qdisc pfifo_fast master br0 state UP mode DEFAULT group default qlen 1000
link/ether be:97:36:d3:3d:71 brd ff:ff:ff:ff:ff:ff
7: swp2: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1468 qdisc pfifo_fast master br0 state DOWN mode DEFAULT group default qlen 1000
link/ether be:97:36:d3:3d:72 brd ff:ff:ff:ff:ff:ff
This cannot be solved by making the interrupts level-triggered,
because the gpio-mpc8xxx controller only supports generating
edge-triggered interrupts. So the effective reality is that we
cannot not use shared interrupts connected to the gpio1
interrupt-parent.
2. The uBUS1 and uBUS2 slots that share this interrupt line with the
Ethernet PHYs are not pulled up by default, they are left floating on
current revisions of the LS1028A-RDB boards. So sufficient electrical
noise on these lines will make the CPLD think there's an interrupt
request, so it asserts the GPIO1_DAT25 signal and leaves it asserted.
This means that the PHYs on those boards will never have link when
used in interrupt mode, because their IRQ will be masked by the uBUS
line that is erroneously kept asserted. In poll mode this issue does
not occur.
