KVM x86 fixes for 6.14-rcN #2 - Set RFLAGS.IF in C code on SVM to get VMRUN out of the STI shadow. - Ensure DEBUGCTL is context switched on AMD to avoid running the guest with the host's value, which can lead to unexpected bus lock #DBs. - Suppress DEBUGCTL.BTF on AMD (to match Intel), as KVM doesn't properly emulate BTF. KVM's lack of context switching has meant BTF has always been broken to some extent. - Always save DR masks for SNP vCPUs if DebugSwap is *supported*, as the guest can enable DebugSwap without KVM's knowledge. - Fix a bug in mmu_stress_tests where a vCPU could finish the "writes to RO memory" phase without actually generating a write-protection fault. - Fix a printf() goof in the SEV smoke test that causes build failures with -Werror. - Explicitly zero EAX and EBX in CPUID.0x8000_0022 output when PERFMON_V2 isn't supported by KVM.
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.
