Subject: [GIT PULL] x86 core updates for v6.16
Linus,

# HEAD: 6a7c3c2606105a41dde81002c0037420bc1ddf00 x86/bugs: Fix spectre_v2 mitigation default on Intel
Merge note: There's a large number of changes outside of arch/x86/,
most of which relate to mechanic changes to the x86 MSR
APIs that do not change semantics. Compatibility wrappers
were added for the most commonly used APIs to reduce/avoid
the pain of merge conflicts & build failures with in-flight
changes in this merge window. In a later stage we'll send
changes to remove the compatibility wrappers and any
leftover uses of the old API names.
Core x86 updates for v6.16:
Boot code changes:
- A large series of changes to reorganize the x86 boot code into a better isolated
and easier to maintain base of PIC early startup code in arch/x86/boot/startup/,
by Ard Biesheuvel.
Motivation & background:
| Since commit
|
| c88d71508e36 ("x86/boot/64: Rewrite startup_64() in C")
|
| dated Jun 6 2017, we have been using C code on the boot path in a way
| that is not supported by the toolchain, i.e., to execute non-PIC C
| code from a mapping of memory that is different from the one provided
| to the linker. It should have been obvious at the time that this was a
| bad idea, given the need to sprinkle fixup_pointer() calls left and
| right to manipulate global variables (including non-pointer variables)
| without crashing.
|
| This C startup code has been expanding, and in particular, the SEV-SNP
| startup code has been expanding over the past couple of years, and
| grown many of these warts, where the C code needs to use special
| annotations or helpers to access global objects.
This tree includes the first phase of this work-in-progress x86 boot code
reorganization.
