If the hypercall was called from userspace or real mode, KVM injects #UD
and then advances RIP, so it looks like #UD was caused by the following
instruction. This probably won't cause more than confusion, but could
give an unexpected access to guest OS' instruction emulator.
Also, refactor the code to count hv hypercalls that were handled by the
virt userspace.

The reason for this error is that the span of MOVABLE_ZONE is extended

If there is a possibility that a VM may migrate to a Skylake host,
then the hypervisor should report IA32_ARCH_CAPABILITIES.RSBA[bit 2]
as being set (future work, of course). This implies that
CPUID.(EAX=7,ECX=0):EDX.ARCH_CAPABILITIES[bit 29] should be
set. Therefore, kvm should report this CPUID bit as being supported
whether or not the host supports it. Userspace is still free to clear
the bit if it chooses.

The CPUID bits of OSXSAVE (function=0x1) and OSPKE (func=0x7, leaf=0x0)
allows user apps to detect if OS has set CR4.OSXSAVE or CR4.PKE. KVM is
supposed to update these CPUID bits when CR4 is updated. Current KVM
code doesn't handle some special cases when updates come from emulator.
Here is one example:
Step 1: guest boots
Step 2: guest OS enables XSAVE ==> CR4.OSXSAVE=1 and CPUID.OSXSAVE=1
Step 3: guest hot reboot ==> QEMU reset CR4 to 0, but CPUID.OSXAVE==1
Step 4: guest os checks CPUID.OSXAVE, detects 1, then executes xgetbv
Step 4 above will cause an #UD and guest crash because guest OS hasn't
turned on OSXAVE yet. This patch solves the problem by comparing the the
old_cr4 with cr4. If the related bits have been changed,
kvm_update_cpuid() needs to be called.

Since 4.10, commit 8003c9ae20 (KVM: LAPIC: add APIC Timer
periodic/oneshot mode VMX preemption timer support), guests using
periodic LAPIC timers (such as FreeBSD 8.4) would see their timers
drift significantly over time.
Differences in the underlying clocks and numerical errors means the
periods of the two timers (hv and sw) are not the same. This
difference will accumulate with every expiry resulting in a large
error between the hv and sw timer.
This means the sw timer may be running slow when compared to the hv
timer. When the timer is switched from hv to sw, the now active sw
timer will expire late. The guest VCPU is reentered and it switches to
using the hv timer. This timer catches up, injecting multiple IRQs
into the guest (of which the guest only sees one as it does not get to
run until the hv timer has caught up) and thus the guest's timer rate
is low (and becomes increasing slower over time as the sw timer lags
further and further behind).
I believe a similar problem would occur if the hv timer is the slower
one, but I have not observed this.
Fix this by synchronizing the deadlines for both timers to the same
time source on every tick. This prevents the errors from accumulating.

Commit 15122ee2c5 ("arm64: Enforce BBM for huge IO/VMAP mappings")
disallowed block mappings for ioremap since that code does not honor
break-before-make. The same APIs are also used for permission updating
though and the extra checks prevent the permission updates from happening,
even though this should be permitted. This results in read-only permissions
not being fully applied. Visibly, this can occasionaly be seen as a failure
on the built in rodata test when the test data ends up in a section or
as an odd RW gap on the page table dump. Fix this by using
pgattr_change_is_safe instead of p*d_present for determining if the
change is permitted.

1. Disable local irq before d-cache write-back and invalidate.
The cpu_dcache_wbinval_page function is composed of d-cache
write-back and invalidate. If the local irq is enabled when calling
cpu_dcache_wbinval_page, the content of d-cache is possibly updated
between write-back and invalidate. In this case, the updated data will
be dropped due to the following d-cache invalidation. Therefore, we
disable the local irq before calling cpu_dcache_wbinval_page.
2. Correct the data write-back for page aliasing case.
Only the page whose (page->index << PAGE_SHIFT) is located at the
same page color as page_address(page) needs to execute data write-back

The nds32 architecture will use physical memory when interrupt or

implementation didn't consider the DRAM start address may start from 1GB,
2GB or 3GB to cause this issue. It will write the data to DRAM if it is
running in physical address however kernel will read the data with
virtaul address through data cache. In this case, the data of DRAM is
latest.
This fix will set the correct cacheability to let kernel write/read the
latest data in cache instead of DRAM.

If userspace faults on a kernel address, handing them the raw ESR
value on the sigframe as part of the delivered signal can leak data
useful to attackers who are using information about the underlying hardware
fault type (e.g. translation vs permission) as a mechanism to defeat KASLR.
However there are also legitimate uses for the information provided
in the ESR -- notably the GCC and LLVM sanitizers use this to report
whether wild pointer accesses by the application are reads or writes
(since a wild write is a more serious bug than a wild read), so we
don't want to drop the ESR information entirely.
For faulting addresses in the kernel, sanitize the ESR. We choose
to present userspace with the illusion that there is nothing mapped
in the kernel's part of the address space at all, by reporting all
faults as level 0 translation faults taken to EL1.
These fields are safe to pass through to userspace as they depend
only on the instruction that userspace used to provoke the fault:
EC IL (always)
ISV CM WNR (for all data aborts)
All the other fields in ESR except DFSC are architecturally RES0
for an L0 translation fault taken to EL1, so can be zeroed out
without confusing userspace.
The illusion is not entirely perfect, as there is a tiny wrinkle
where we will report an alignment fault that was not due to the memory
type (for instance a LDREX to an unaligned address) as a translation
fault, whereas if you do this on real unmapped memory the alignment
fault takes precedence. This is not likely to trip anybody up in
practice, as the only users we know of for the ESR information who
care about the behaviour for kernel addresses only really want to
know about the WnR bit.

On some CPUs we can prevent a vulnerability related to store-to-load
forwarding by preventing store forwarding between privilege domains,
by inserting a barrier in kernel entry and exit paths.
This is known to be the case on at least Power7, Power8 and Power9
powerpc CPUs.
Barriers must be inserted generally before the first load after moving
to a higher privilege, and after the last store before moving to a
lower privilege, HV and PR privilege transitions must be protected.
Barriers are added as patch sections, with all kernel/hypervisor entry
points patched, and the exit points to lower privilge levels patched
similarly to the RFI flush patching.
Firmware advertisement is not implemented yet, so CPU flush types
are hard coded.

For LSE atomics that read and write a register operand, we need to
ensure that these operands are annotated as "early clobber" if the

Failure to do so can result in the compiler allocating the same register
to both operands, leading to splats such as:
Unable to handle kernel paging request at virtual address 11111122222221

where x0 has been allocated as both the value to be stored and also the
