  x86/coco: Define cc_vendor without CONFIG_ARCH_HAS_CC_PLATFORM (2024-02-06 03:56:04 -0500)

This missed -rc3 due to an issue with clang compilation, which is solved by
the top commit.

----------------------------------------------------------------
x86 guest:

* Avoid false positive for check that only matters on AMD processors

x86:

* Give a hint when Win2016 might fail to boot due to XSAVES && !XSAVEC configuration

* Do not allow creating an in-kernel PIT unless an IOAPIC already exists

RISC-V:

* Allow ISA extensions that were enabled for bare metal in 6.8
  (Zbc, scalar and vector crypto, Zfh[min], Zihintntl, Zvfh[min], Zfa)

S390:

* fix CC for successful PQAP instruction

* fix a race when creating a shadow page
