Pull x86 fixes from Borislav Petkov: - Remove a transitional asm/cpuid.h header which was added only as a fallback during cpuid helpers reorg - Initialize reserved fields in the SVSM page validation calls structure to zero in order to allow for future structure extensions - Have the sev-guest driver's buffers used in encryption operations be in linear mapping space as the encryption operation can be offloaded to an accelerator - Have a read-only MSR write when in an AMD SNP guest trap to the hypervisor as it is usually done. This makes the guest user experience better by simply raising a #GP instead of terminating said guest - Do not output AVX512 elapsed time for kernel threads because the data is wrong and fix a NULL pointer dereferencing in the process - Adjust the SRSO mitigation selection to the new attack vectors * tag 'x86_urgent_for_v6.17_rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/cpuid: Remove transitional <asm/cpuid.h> header x86/sev: Ensure SVSM reserved fields in a page validation entry are initialized to zero virt: sev-guest: Satisfy linear mapping requirement in get_derived_key() x86/sev: Improve handling of writes to intercepted TSC MSRs x86/fpu: Fix NULL dereference in avx512_status() x86/bugs: Select best SRSO mitigation
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
