[PATCH] arm64/efi: set PE/COFF file alignment to 512 bytes

[PATCH] arm64/efi: set PE/COFF file alignment to 512 bytes

[Ard Biesheuvel]

Change our PE/COFF header to use the minimum file alignment of
512 bytes (0x200), as mandated by the PE/COFF spec v8.3

Also update the linker script so that the Image file itself is also a
round multiple of FileAlignment.

Another one from the PE/COFF rabbit hole. I will follow up next week and repost
as a coherent series, once I have collected all the feedback.

It appears a though next week never came.

Should I pick up this version and apply ACK tags from the mailing list?
Or are you planning on sending a larger series?

It sounds like this should be tagged for stable, and placed into the EFI
urgent queue?

It appears a though next week never came.

Should I pick up this version and apply ACK tags from the mailing list?
Or are you planning on sending a larger series?

It sounds like this should be tagged for stable, and placed into the EFI
urgent queue?

I have a couple of patches like this one in my queue, and I don't
think any of them are urgent. These alignment fixes etc are mainly for
full compliance with the various specs, and there are no known issues
being solved by them.

I was going to wait for -rc1 and rebase on top of that, but it appears
your branch hasn't been picked up?
