Wire up the new clone3 syscall added in commit 7f192e3cd316 ("fork:

This requires a ppc_clone3 wrapper, in order to save the non-volatile

Pick up the spectre documentation so the Grand Schemozzle can be added.

Intel provided the following information:
On all current Atom processors, instructions that use a segment register
value (e.g. a load or store) will not speculatively execute before the
last writer of that segment retires. Thus they will not use a
speculatively written segment value.
That means on ATOMs there is no speculation through SWAPGS, so the SWAPGS
entry paths can be excluded from the extra LFENCE if PTI is disabled.
Create a separate bug flag for the through SWAPGS speculation and mark all
out-of-order ATOMs and AMD/HYGON CPUs as not affected. The in-order ATOMs
are excluded from the whole mitigation mess anyway.

To help avoid confusion, add a comment to ghash-generic.c which explains
the convention that the kernel's implementation of GHASH uses.
Also update the Kconfig help text and module descriptions to call GHASH
a "hash function" rather than a "message digest", since the latter
normally means a real cryptographic hash function, which GHASH is not.

The issue is generated by the fact that "if_changed" is called twice
in a single target.
Fix the build bug merging the two commands into a single function.

The vdso library for o32 and n32 does not compile compile correctly when
building outside of the source tree due to a wrong inclusion path for
config-n32-o32-env.c resulting in the error below:

We've added two ESR exception classes for new ARM hardware extensions:
ESR_ELx_EC_PAC and ESR_ELx_EC_SVE, but failed to update the strings
used in tracing and other debug.
Let's update "kvm_arm_exception_class" for these two EC, which the
new EC will be visible to user-space via kvm_exit trace events
Also update to "esr_class_str" for ESR_ELx_EC_PAC, by which we can
get more readable debug info.

Rework to add a 'break;' in the swich-case since it didn't have that,
leading to an interresting set of bugs.
