Hi all,
This is a follow up to the vDSO linker script fixes, that was pulled into the
arm64 tree.
Patch 1 fixes the issue found by Will:
https://lore.kernel.org/linux-arm-kernel/20220623175352.GA17471@willie-the-truck/
Patch 2 fixes the comments Vincenzo had:
https://lore.kernel.org/linux-arm-kernel/00abb0c5-6360-0004-353f-e7a88b3bd22c@arm.com/o
This is based on for-next/vdso: 2d304afaedc4 ("arm64: compat: Move kuser32.S to .rodata section")
Thanks,
Joey
