Cover letter [PATCH v3 0/2] arm64 sigreturn unwinding fixes
Hi folks,
Here is v3 of my attempt at fixing the vdso sigreturn code for unwinders. Previous versions are available here:
v1: https://lore.kernel.org/r/[email protected]
v2: https://lore.kernel.org/r/[email protected]
Changes since v2 include:
* Fix the .cfi directives to identify the link register correctly
* Even more comments
Daniel, please can you give this a spin with the LLVM unwinder? It should work this time.
Cheers,
Will
