Subject: [PATCHv2 0/3] arm64: clean up trampoline alignment
Date: Mon, 16 Mar 2020 14:40:49 +0200 [thread overview]
Message-ID: <4064091.qgymGCTE6G@basile.remlab.net> (raw)
Hi,
The KPTI and SDE trampolines each load a pointer from the same fixmap data
page. This reduces the data alignment to the useful value, and tries to
clarify the assembler code.
----------------------------------------------------------------
Rémi Denis-Courmont (3):
arm64: clean up trampoline vector loads
arm64/sdei: gather trampolines' .rodata
arm64: reduce trampoline data alignment
