Subject: [PATCH fsgsbase v2 0/4] x86/fsgsbase: Some fixes
Date: Fri, 26 Jun 2020 10:24:26 -0700 [thread overview]
Message-ID: <cover.1593192140.git.luto@kernel.org> (raw)

The first two are trivial selftest fixes. The third one fixes an actual
regression. The forth one fixes a crash on boot on Xen PV.

selftests/x86/fsgsbase: Fix a comment in the ptrace_write_gsbase test
selftests/x86/fsgsbase: Add a missing memory constraint
x86/ptrace: Fix 32-bit PTRACE_SETREGS vs fsbase and gsbase
x86/fsgsbase: Fix Xen PV support
