Hi Joey,

I've applied this locally, but I'm seeing a warning from LLD when linking
the 32-bit vDSO object:

  | LD32    arch/arm64/kernel/vdso32/vdso.so.raw
  | ld.lld: warning: <internal>:(.ARM.exidx) is being placed in '.ARM.exidx'

Please can you take a look and send an additional patch on top to fix this?

Thanks,

Will
