Subject: [GIT PULL] x86/urgent for v6.2-rc6
Hi Linus,
please pull a bunch of urgent x86 fixes for 6.2.
The SEV-SNP patch looks a bit largish and perhaps, at a first glance, not really
urgent material but the intent behind it is to fail gracefully when booting
older kernels on newer hypervisors when latter support features which those
older kernels do not know of yet.
Therefore, it should go to stable so sending it now is as good a time as any.
Please pull,
thanks.

x86/build: Move '-mindirect-branch-cs-prefix' out of GCC-only block (2023-01-22 11:36:45 +0100)
----------------------------------------------------------------
- Start checking for -mindirect-branch-cs-prefix clang support too now that LLVM
16 will support it
- Fix a NULL ptr deref when suspending with Xen PV
- Have a SEV-SNP guest check explicitly for features enabled by the hypervisor
and fail gracefully if some are unsupported by the guest instead of failing in
a non-obvious and hard-to-debug way
- Fix a MSI descriptor leakage under Xen
- Mark Xen's MSI domain as supporting MSI-X
- Prevent legacy PIC interrupts from being resent in software by marking them
level triggered, as they should be, which lead to a NULL ptr deref
