Hello Linus,
Please consider the changes below for v6.8.
Only notable change here is the patch that changes the way we deal with
spurious errors from the EFI memory attribute protocol. This will be backported
to v6.6, and is intended to ensure that we will not paint ourselves into a
corner when we tighten this further in order to comply with MS requirements on
signed EFI code. Note that this protocol does not currently exist in x86
production systems in the field, only in Microsoft's fork of OVMF, but it will
be mandatory for Windows logo certification for x86 PCs in the future.
The following changes since commit 6613476e225e090cc9aad49be7fa504e290dd33d:

x86/efistub: Use 1:1 file:memory mapping for PE/COFF .compat section (2024-02-05 10:24:51 +0000)
----------------------------------------------------------------
EFI fixes for v6.8 #1
- Tighten ELF relocation checks on the RISC-V EFI stub
- Give up if the new EFI memory attributes protocol fails spuriously on
x86
- Take care not to place the kernel in the lowest 16 MB of DRAM on x86
- Omit special purpose EFI memory from memblock
- Some fixes for the CXL CPER reporting code
- Make the PE/COFF layout of mixed-mode capable images comply with a
strict interpretation of the spec
