# HEAD: e9524fb97ab5b41b85e1d3408f8e513433798f3c efi/x86: Don't blow away existing initrd
The EFI changes for this cycle are:
- preliminary changes for RISC-V
- Add support for setting the resolution on the EFI framebuffer
- Simplify kernel image loading for arm64
- Move .bss into .data via the linker script instead of relying on symbol
annotations.
- Get rid of __pure getters to access global variables
- Clean up the config table matching arrays
- Rename pr_efi/pr_efi_err to efi_info/efi_err, and use them consistently
- Simplify and unify initrd loading
- Parse the builtin command line on x86 (if provided)
- Implement printk() support, including support for wide character strings
- Simplify GDT handling in early mixed mode thunking code
- Some other minor fixes and cleanups
Thanks,
Ingo

Please note that Stephen reported a conflict with the ARM32 tree, due
to the replacement of all instances of pr_efi_err() with efi_err(),
including a couple in some ARM code that is being modified.

Indeed!
Since these semantic conflicts and build failures would not trigger on
Linus's test builds normally, it might make sense to double check that
this comes up empty after both the EFI and the arm32 merge:
thule:~/tip> git grep -w pr_efi_err
thule:~/tip>
Thanks,
Ingo

Ok, I'll try to remember, but I probably won't. So it would be lovely
to be reminded when I get the arm pull.
That said, if it's just outright conflicts, that's not a big deal and
the resolution looks trivial. But if there are actual semantic
conflicts that don't show up during the merge like Ingo implies, I
would indeed not notice due to me not doing any cross-builds.

Well, the arm pull already came in, and mentioned it, and it all
looked entirely local and simple, so it's all good.
Or rather, it's all _potentially_ good, but completely untested by yours truly.
rmk said he'd take a look, but maybe Ard might want to peek at it too.

Pulled, thanks a lot Ard! Will push it out after a bit of testing.
There was one conflict, in drivers/firmware/efi/libstub/efistub.h,
with a straightforward resolution.

Ingo, Thomsd, Boris,
Please pull the changes below. Note that I did not incorporate the GOT
handling changes for the x86 decompressor - Arvind has some changes on
top that might just as well go in at the same time, and they are not
really EFI changes anyway.
The following changes since commit 4da0b2b7e67524cc206067865666899bc02e1cb0:
efi/libstub: Re-enable command line initrd loading for x86 (2020-04-25 12:26:32 +0200)
