Sasha reported a lockdep splat about a potential deadlock between RCU boosting
rtmutex and the posix timer it_lock.
CPU0 CPU1
rtmutex_lock(&rcu->rt_mutex)
spin_lock(&rcu->rt_mutex.wait_lock)
local_irq_disable()
spin_lock(&timer->it_lock)
spin_lock(&rcu->mutex.wait_lock)
--> Interrupt
spin_lock(&timer->it_lock)
This is caused by the following code sequence on CPU1
rcu_read_lock()
x = lookup();
if (x)
spin_lock_irqsave(&x->it_lock);
rcu_read_unlock();
return x;
We could fix that in the posix timer code by keeping rcu read locked across
the spinlocked and irq disabled section, but the above sequence is common and
there is no reason not to support it.
Taking rt_mutex.wait_lock irq safe prevents the deadlock.

This adds micro-benchmarks useful for tuning virtio ring layouts.
Three layouts are currently implemented:
- virtio 0.9 compatible one
- an experimental extension bypassing the ring index, polling ring
itself instead
- an experimental extension bypassing avail and used ring completely
Typical use:
sh run-on-all.sh perf stat -r 10 --log-fd 1 -- ./ring
It doesn't depend on the kernel directly, but it's handy
to have as much virtio stuff as possible in one tree.

commit 90a3ccb0be ("sh: define __smp_xxx,

left the bug in place.

We need a single mutex for all 4 shared SMBus ports on the SB800. A
per-port mutex doesn't protect us from concurrent access.
In theory the mutex should be per PCI device, however in practice we
know that there's only ever a single instance of the device in a given
system so we can use a global.
Also take the mutex during initialization, as first port may be already
in use when second port is initialized.

An fsync, using the fast path, can race with a concurrent lockless direct
IO write and end up logging a file extent item that points to an extent
that wasn't written to yet. This is because the fast fsync path collects
ordered extents into a local list and then collects all the new extent
maps to log file extent items based on them, while the direct IO write
path creates the new extent map before it creates the corresponding
ordered extent (and submitting the respective bio(s)).
So fix this by making the direct IO write path create ordered extents
before the extent maps and make the fast fsync path collect any new
ordered extents after it collects the extent maps.
Note that making the fsync handler call inode_dio_wait() (after acquiring
the inode's i_mutex) would not work and lead to a deadlock when doing
AIO, as through AIO we end up in a path where the fsync handler is called
(through dio_aio_complete_work() -> dio_complete() -> vfs_fsync_range())
before the inode's dio counter is decremented (inode_dio_wait() waits
for this counter to have a value of zero).

Some architectures like PowerPC can handle the maximum struct size in
an ioctl only up to 13 bits, and struct snd_compr_codec_caps used by
SNDRV_COMPRESS_GET_CODEC_CAPS ioctl overflows this limit. This
problem was revealed recently by a powerpc change, as it's now treated
as a fatal build error.
This patch is a stop-gap for that: for architectures with less than 14
bit ioctl struct size, get rid of the handling of the relevant ioctl.
We should provide an alternative equivalent ioctl code later, but for
now just paper over it. Luckily, the compress API hasn't been used on
such architectures, so the impact must be effectively zero.

Currently, set_pte_at() only checks the software PTE_WRITE bit for user
mappings when it sets or clears the hardware PTE_RDONLY accordingly. The
kernel ptes are written directly without any modification, relying
solely on the protection bits in macros like PAGE_KERNEL. However,
modifying kernel pte attributes via pte_wrprotect() would be ignored by
set_pte_at(). Since pte_wrprotect() does not set PTE_RDONLY (it only
clears PTE_WRITE), the new permission is not taken into account.
This patch changes set_pte_at() to adjust the read-only permission for
kernel ptes as well. As a side effect, existing PROT_* definitions used
for kernel ioremap*() need to include PTE_DIRTY | PTE_WRITE.

before accessing them.
This patch implements a guard by reading the ID_AA64DFR0_EL1 register
PMUVer field to detect the architected PMU presence and prevent accessing

Commit e8f3010f73 ("arm64/efi: isolate EFI stub from the kernel
proper") isolated the EFI stub code from the kernel proper by prefixing
all of its symbols with __efistub_, and selectively allowing access to
core kernel symbols from the stub by emitting __efistub_ aliases for
functions and variables that the stub can access legally.
As an unintended side effect, these aliases are emitted into the
kallsyms symbol table, which means they may turn up in backtraces,
e.g.,
...
PC is at __efistub_memset+0x108/0x200
LR is at fixup_init+0x3c/0x48
...
[<ffffff8008328608>] __efistub_memset+0x108/0x200
[<ffffff8008094dcc>] free_initmem+0x2c/0x40
[<ffffff8008645198>] kernel_init+0x20/0xe0
[<ffffff8008085cd0>] ret_from_fork+0x10/0x40
The backtrace in question has nothing to do with the EFI stub, but
simply returns one of the several aliases of memset() that have been
recorded in the kallsyms table. This is undesirable, since it may
suggest to people who are not aware of this that the issue they are
seeing is somehow EFI related.
So hide the __efistub_ aliases from kallsyms, by emitting them as
absolute linker symbols explicitly. The distinction between those
and section relative symbols is completely irrelevant to these
definitions, and to the final link we are performing when these
definitions are being taken into account (the distinction is only
relevant to symbols defined inside a section definition when performing
a partial link), and so the resulting values are identical to the
original ones. Since absolute symbols are ignored by kallsyms, this
will result in these values to be omitted from its symbol table.
After this patch, the backtrace generated from the same address looks
like this:
...
PC is at __memset+0x108/0x200
LR is at fixup_init+0x3c/0x48
...
[<ffffff8008328608>] __memset+0x108/0x200
