Hi Greg,
This patch depends on three prerequisites. This full list of commit ids should be backported is shown below,
- 65d9a9a60fd7 ("kexec_file: drop weak attribute from functions")
- 689a71493bd2 ("kexec: clean up arch_kexec_kernel_verify_sig")
- c903dae8941d ("kexec, KEYS: make the code in bzImage64_verify_sig generic")
- 0d519cadf751 ("arm64: kexec_file: use more system keyrings to verify kernel image signature")
And I can confirm they can be applied to linux-5.15.y branch successfully, $ git checkout -b arm_key_5.15.y stable/linux-5.15.y branch 'arm_key_5.15.y' set up to track 'stable/linux-5.15.y'.

thanks, now queued up.
Nope, it causes build breakages in powerpc :(
See: https://lore.kernel.org/r/YwC6eQjx8xC9y3LD@debian and https://lore.kernel.org/r/CA+G9fYtXnZP2vdAi4eU_ApC_YFz6TqTd6Eh5Mumb2=0Y_dK5Y...
for the reports. I'm dropping these from 5.15.y now, please fix this up and resend if you want them included.
thanks,
