[PATCH 0/2] Stop generating .eh_frame sections

[Arvind Sankar]

In three places in the x86 kernel we are currently generating .eh_frame
sections only to discard them later via linker script. This is in the
boot code (setup.elf), the realmode trampoline (realmode.elf) and the
compressed kernel.

Implement Fangrui and Nick's suggestion [1] to fix KBUILD_CFLAGS by
adding -fno-asynchronous-unwind-tables to avoid generating .eh_frame
sections in the first place, rather than discarding it in the linker
script.

Arvind Sankar (2):
  arch/x86: Use -fno-asynchronous-unwind-tables to suppress .eh_frame sections
  arch/x86: Drop unneeded linker script discard of .eh_frame
