a194c5f2d2 arm64/mm: return cpu_all_mask when node is NUMA_NO_NODE
The @node passed to cpumask_of_node() can be NUMA_NO_NODE, in that
case it will trigger the following WARN_ON(node >= nr_node_ids) due to
mismatched data types of @node and @nr_node_ids. Actually we should
return cpu_all_mask just like most other architectures do if passed
NUMA_NO_NODE.

Also add a similar check to the inline cpumask_of_node() in numa.h.

2cf660eb81 arm64/mm: Refactor {pgd, pud, pmd, pte}_ERROR()
The function __{pgd, pud, pmd, pte}_error() are introduced so that
they can be called by {pgd, pud, pmd, pte}_ERROR(). However, some
of the functions could never be called when the corresponding page
table level isn't enabled. For example, __{pud, pmd}_error() are
unused when PUD and PMD are folded to PGD.

This removes __{pgd, pud, pmd, pte}_error() and call pr_err() from
{pgd, pud, pmd, pte}_ERROR() directly, similar to what x86/powerpc
are doing. With this, the code looks a bit simplified either.

120dc60d0b arm64: get rid of TEXT_OFFSET
TEXT_OFFSET serves no purpose, and for this reason, it was redefined
as 0x0 in the v5.8 timeframe. Since this does not appear to have caused
any issues that require us to revisit that decision, let's get rid of the
macro entirely, along with any references to it.

b4c9712459 arm64: traps: Add str of description to panic() in die()
Currently, there are different description strings in die() such as
die("Oops",,), die("Oops - BUG",,). And panic() called by die() will
always show "Fatal exception" or "Fatal exception in interrupt".

Note that panic() will run any panic handler via panic_notifier_list.
And the string above will be formatted and placed in static buf[]
which will be passed to handler.

So panic handler can not distinguish which Oops it is from the buf if
we want to do some things like reserve the string in memory or panic
statistics. It's not benefit to debug. We need to add more codes to
troubleshoot. Let's utilize existing resource to make debug much simpler.

dcc5c6f013 Three interrupt related fixes for X86:
- Move disabling of the local APIC after invoking fixup_irqs() to ensure
    that interrupts which are incoming are noted in the IRR and not ignored.
 
  - Unbreak affinity setting. The rework of the entry code reused the
    regular exception entry code for device interrupts. The vector number is
    pushed into the errorcode slot on the stack which is then lifted into an
    argument and set to -1 because that's regs->orig_ax which is used in
    quite some places to check whether the entry came from a syscall. But it
    was overlooked that orig_ax is used in the affinity cleanup code to
    validate whether the interrupt has arrived on the new target. It turned
    out that this vector check is pointless because interrupts are never
    moved from one vector to another on the same CPU. That check is a
    historical leftover from the time where x86 supported multi-CPU
    affinities, but not longer needed with the now strict single CPU
    affinity. Famous last words ...
 
  - Add a missing check for an empty cpumask into the matrix allocator. The
    affinity change added a warning to catch the case where an interrupt is
    moved on the same CPU to a different vector. This triggers because a
    condition with an empty cpumask returns an assignment from the allocator
    as the allocator uses for_each_cpu() without checking the cpumask for
    being empty. The historical inconsistent for_each_cpu() behaviour of
    ignoring the cpumask and unconditionally claiming that CPU0 is in the
    mask striked again. Sigh.

8bb5021cc2 powerpc fixes for 5.9 #4
Revert our removal of PROT_SAO, at least one user expressed an interest in using
 it on Power9. Instead don't allow it to be used in guests unless enabled
 explicitly at compile time.
 
 A fix for a crash introduced by a recent change to FP handling.
 
 Revert a change to our idle code that left Power10 with no idle support.
 
 One minor fix for the new scv system call path to set PPR.
 
 Fix a crash in our "generic" PMU if branch stack events were enabled.
 
 A fix for the IMC PMU, to correctly identify host kernel samples.
 
 The ADB_PMU powermac code was found to be incompatible with VMAP_STACK, so make
 them incompatible in Kconfig until the code can be fixed.
 
 A build fix in drivers/video/fbdev/controlfb.c, and a documentation fix.

784a083037 genirq/matrix: Deal with the sillyness of for_each_cpu() on UP
Most of the CPU mask operations behave the same way, but for_each_cpu() and
it's variants ignore the cpumask argument and claim that CPU0 is always in
the mask. This is historical, inconsistent and annoying behaviour.

The matrix allocator uses for_each_cpu() and can be called on UP with an
empty cpumask. The calling code does not expect that this succeeds but
until commit e027fffff7 ("x86/irq: Unbreak interrupt affinity setting")
this went unnoticed. That commit added a WARN_ON() to catch cases which
move an interrupt from one vector to another on the same CPU. The warning
triggers on UP.

Add a check for the cpumask being empty to prevent this.

Fixes: 2f75d9e1c9 ("genirq: Implement bitmap matrix allocator")

0a4c56c80f fsldma: fix very broken 32-bit ppc ioread64 functionality
Commit ef91bb196b ("kernel.h: Silence sparse warning in
lower_32_bits") caused new warnings to show in the fsldma driver, but
that commit was not to blame: it only exposed some very incorrect code
that tried to take the low 32 bits of an address.

That made no sense for multiple reasons, the most notable one being that
that code was intentionally limited to only 32-bit ppc builds, so "only
low 32 bits of an address" was completely nonsensical.  There were no
high bits to mask off to begin with.

But even more importantly fropm a correctness standpoint, turning the
address into an integer then caused the subsequent address arithmetic to
be completely wrong too, and the "+1" actually incremented the address
by one, rather than by four.

Which again was incorrect, since the code was reading two 32-bit values
and trying to make a 64-bit end result of it all.  Surprisingly, the
iowrite64() did not suffer from the same odd and incorrect model.

This code has never worked, but it's questionable whether anybody cared:
of the two users that actually read the 64-bit value (by way of some C
preprocessor hackery and eventually the 'get_cdar()' inline function),
one of them explicitly ignored the value, and the other one might just
happen to work despite the incorrect value being read.

This patch at least makes it not fail the build any more, and makes the
logic superficially sane.  Whether it makes any difference to the code
_working_ or not shall remain a mystery.

71a7f8cb1c KVM: arm64: Set HCR_EL2.PTW to prevent AT taking synchronous exception
AT instructions do a translation table walk and return the result, or
the fault in PAR_EL1. KVM uses these to find the IPA when the value is
not provided by the CPU in HPFAR_EL1.

If a translation table walk causes an external abort it is taken as an
exception, even if it was due to an AT instruction. (DDI0487F.a's D5.2.11
"Synchronous faults generated by address translation instructions")

While we previously made KVM resilient to exceptions taken due to AT
instructions, the device access causes mismatched attributes, and may
occur speculatively. Prevent this, by forbidding a walk through memory
described as device at stage2. Now such AT instructions will report a
stage2 fault.

Such a fault will cause KVM to restart the guest. If the AT instructions
always walk the page tables, but guest execution uses the translation cached
in the TLB, the guest can't make forward progress until the TLB entry is
evicted. This isn't a problem, as since commit 5dcd0fdbb4 ("KVM: arm64:
Defer guest entry when an asynchronous exception is pending"), KVM will
return to the host to process IRQs allowing the rest of the system to keep
running.

88a84ccccb KVM: arm64: Survive synchronous exceptions caused by AT instructions
KVM doesn't expect any synchronous exceptions when executing, any such
exception leads to a panic(). AT instructions access the guest page
tables, and can cause a synchronous external abort to be taken.

The arm-arm is unclear on what should happen if the guest has configured
the hardware update of the access-flag, and a memory type in TCR_EL1 that
does not support atomic operations. B2.2.6 "Possible implementation
restrictions on using atomic instructions" from DDI0487F.a lists
synchronous external abort as a possible behaviour of atomic instructions
that target memory that isn't writeback cacheable, but the page table
walker may behave differently.

Make KVM robust to synchronous exceptions caused by AT instructions.
Add a get_user() style helper for AT instructions that returns -EFAULT
if an exception was generated.

While KVM's version of the exception table mixes synchronous and
asynchronous exceptions, only one of these can occur at each location.

Re-enter the guest when the AT instructions take an exception on the
assumption the guest will take the same exception. This isn't guaranteed
to make forward progress, as the AT instructions may always walk the page
tables, but guest execution may use the translation cached in the TLB.

This isn't a problem, as since commit 5dcd0fdbb4 ("KVM: arm64: Defer guest
entry when an asynchronous exception is pending"), KVM will return to the
host to process IRQs allowing the rest of the system to keep running.

e9ee186bb7 KVM: arm64: Add kvm_extable for vaxorcism code
KVM has a one instruction window where it will allow an SError exception
to be consumed by the hypervisor without treating it as a hypervisor bug.
This is used to consume asynchronous external abort that were caused by
the guest.

As we are about to add another location that survives unexpected exceptions,
generalise this code to make it behave like the host's extable.

KVM's version has to be mapped to EL2 to be accessible on nVHE systems.

The SError vaxorcism code is a one instruction window, so has two entries
in the extable. Because the KVM code is copied for VHE and nVHE, we end up
with four entries, half of which correspond with code that isn't mapped.

1764c3edc6 arm64: use a common .arch preamble for inline assembly
Commit 7c78f67e9b ("arm64: enable tlbi range instructions") breaks
LLVM's integrated assembler, because -Wa,-march is only passed to
external assemblers and therefore, the new instructions are not enabled
when IAS is used.

This change adds a common architecture version preamble, which can be
used in inline assembly blocks that contain instructions that require
a newer architecture version, and uses it to fix __TLBI_0 and __TLBI_1
with ARM64_TLB_RANGE.

Commit e49aa9a9bd22 ("mfd: core: Make a best effort attempt to match
devices with the correct of_nodes") changed the semantics for disabled
devices in mfd_add_device().  Instead of silently ignoring a disabled
child device, an error was returned.  On receipt of the error
mfd_add_devices() the precedes to remove *all* child devices and
returns an all-failed error to the caller, which will inevitably fail
the parent device as well.

This patch reverts back to the old semantics and ignores child devices
which are disabled in Device Tree.

In fact, we should make sure stripe_size as power of two. Otherwise,
stripe_shift which is the result of ilog2 can not represent the real
stripe_size. Then, stripe_hash() and stripe_hash_locks_hash() may
