Subject: [PATCH 0/6] x86/entry: Fixes
Date: Fri, 26 Jun 2020 10:21:10 -0700	[thread overview]
Message-ID: <cover.1593191971.git.luto@kernel.org> (raw)

Half of this is selftests.  The rest adds some confidence-improving
assertions and fixes a crash when running on Xen PV.

Andy Lutomirski (6):
  x86/entry: Assert that syscalls are on the right stack
  x86/entry: Move SYSENTER's regs->sp and regs->flags fixups into C
  x86/entry/64/compat: Fix Xen PV SYSENTER frame setup
  selftests/x86/syscall_nt: Add more flag combinations
  selftests/x86/syscall_nt: Clear weird flags after each test
  selftests/x86: Consolidate and fix get/set_eflags() helpers
