Applied to arm64 (for-next/scs), thanks!
[1/2] scs: switch to vmapped shadow stacks https://git.kernel.org/arm64/c/a2abe7cbd8fe [2/2] arm64: scs: use vmapped IRQ and SDEI shadow stacks https://git.kernel.org/arm64/c/ac20ffbb0279
I also threw a patch on top implementing the suggestion I made on v2, so please take a look if you get a chance.
Cheers, -- Will
