Pull EFI fixes from Ard Biesheuvel:

 - Force the use of SetVirtualAddressMap() on Ampera Altra arm64
   machines, which crash in SetTime() if no virtual remapping is used

   This is the first time we've added an SMBIOS based quirk on arm64,
   but fortunately, we can just call a EFI protocol to grab the type #1
   SMBIOS record when running in the stub, so we don't need all the
   machinery we have in the kernel proper to parse SMBIOS data.

 - Drop a spurious warning on misaligned runtime regions when using 16k
   or 64k pages on arm64

Ampere Altra machines are reported to misbehave when the SetTime() EFI
runtime service is called after ExitBootServices() but before calling
SetVirtualAddressMap(). Given that the latter is horrid, pointless and
explicitly documented as optional by the EFI spec, we no longer invoke
it at boot if the configured size of the VA space guarantees that the
EFI runtime memory regions can remain mapped 1:1 like they are at boot
time.

On Ampere Altra machines, this results in SetTime() calls issued by the
rtc-efi driver triggering synchronous exceptions during boot.  We can
now recover from those without bringing down the system entirely, due to
commit 23715a26c8d81291 ("arm64: efi: Recover from synchronous
exceptions occurring in firmware"). However, it would be better to avoid
the issue entirely, given that the firmware appears to remain in a funny
state after this.

So attempt to identify these machines based on the 'family' field in the
type #1 SMBIOS record, and call SetVirtualAddressMap() unconditionally
in that case.

Pull slab fixes from Vlastimil Babka:
 "Most are small fixups as described below.

  The !CONFIG_TRACING fix is a bit bigger and would normally be done in
  the next merge window as part of upcoming hardening changes. But we
  realized it can make the kmalloc waste tracking introduced in this
  window inaccurate, so decided to go with it now.

  Summary:

   - Remove !CONFIG_TRACING kmalloc() wrappers intended to save a
     function call, due to incompatilibity with recently introduced
     wasted space tracking and planned hardening changes.

Along the development cycle, the testing code support for module/in-kernel
compiles was removed.  Restore this functionality by moving any internal
API tests to the userspace side, as well as threading tests.  Fix the
lockdep issues and add a way to reduce memory usage so the tests can
complete with KASAN + memleak detection.  Make the tests work on 32 bit
hosts where possible and detect 32 bit hosts in the radix test suite.

In commit a6d190f8c767 ("can: skb: drop tx skb if in listen only
mode") the priv->ctrlmode element is read even on virtual CAN
interfaces that do not create the struct can_priv at startup. This
out-of-bounds read may lead to CAN frame drops for virtual CAN
interfaces like vcan and vxcan.

This patch mainly reverts the original commit and adds a new helper
for CAN interface drivers that provide the required information in
struct can_priv.

For !CONFIG_TRACING kernels, the kmalloc() implementation tries (in cases where
the allocation size is build-time constant) to save a function call, by
inlining kmalloc_trace() to a kmem_cache_alloc() call.

However since commit 6edf2576a6cc ("mm/slub: enable debugging memory wasting of
kmalloc") this path now fails to pass the original request size to be
eventually recorded (for kmalloc caches with debugging enabled).

We could adjust the code to call __kmem_cache_alloc_node() as the
CONFIG_TRACING variant, but that would as a result inline a call with 5
parameters, bloating the kmalloc() call sites. The cost of extra function
call (to kmalloc_trace()) seems like a lesser evil.

It also appears that the !CONFIG_TRACING variant is incompatible with upcoming
hardening efforts [1] so it's easier if we just remove it now. Kernels with no
tracing are rare these days and the benefit is dubious anyway.
