v2:
add separate patch to rename the decompressor's version of the
boot_params global variable

Ard Biesheuvel (2):
  x86/boot: Rename conflicting boot_params pointer to boot_params_p
  x86/boot: efistub: Assign global boot_params variable

Thanks!

I renamed 'boot_params_p' to 'boot_params_ptr' for clarity - fortunately 
haven't run out of 't' and 'r' letters yet in the kernel.

Thanks,

OK thanks.

I noticed you queued this up for v6.7.
So what should we do for v6.6 wrt the second patch?

I presumed you'd queue it up in the EFI tree, and I'll merge it & resolve 
the conflict once it hits upstream?

Thanks,
