Hi Linus,
Please pull the fix below. This is going be backported to v6.1 and later to
address the regression described in the commit. Whether or not physical KASLR
for the cases in question will be brought back later (presumably by sharing the
physical placement logic with the traditional decompressor) is as yet
undecided.
The following changes since commit 4b2543f7e1e6b91cfc8dd1696e3cdf01c3ac8974:
efi: libstub: only free priv.runtime_map when allocated (2024-04-29 17:47:32 +0200)

x86/efistub: Omit physical KASLR when memory reservations exist (2024-05-17 17:06:18 +0200)
----------------------------------------------------------------
EFI fixes for v6.10 #1
- Followup fix for the EFI boot sequence refactor, which may result in
physical KASLR putting the kernel in a region which is being used for
a special purpose via a command line argument.
