[PATCHv3 0/3] clean up KPTI / SDEI trampoline data alignment
From: Rémi Denis-Courmont
Date: Thu Mar 19 2020 - 05:13:02 EST
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.
Changes since v2:
- Retain alignment even when SDEI is disabled to keep ld happy.

arm64: clean up trampoline vector loads
arm64/sdei: gather trampolines' .rodata
arm64: reduce trampoline data alignment
