Subject: [PATCH 0/1] x86/fault: cleanup: move x86-64 test into is_vsyscall_vaddr()
Date: Thu, 5 Mar 2026 15:21:34 -0800 [thread overview]
Message-ID: <20260305232136.224922-1-hpa@zytor.com> (raw)
In-Reply-To: <20260305214026.3887452-1-sohil.mehta@intel.com>
Reviewing Sohil's LASS patchset inspired me to cook up a very small
cleanup patch, removing some unnecessary conditional compilation. It
is on top of Sohil's patchset, but it is really orthogonal to it; the
patch applies with fuzz (line changes and the renaming of
emulate_vsyscall() to emulate_vsyscall_pf() in the context) to the
unmodified upstream kernel as well.
