[GIT PULL] EFI fixes for v6.9 #2

[Ard Biesheuvel]

From: Ard Biesheuvel <ardb@kernel.org>

Hi Linus,

A steady trickle of EFI fixes this cycle - this is due to the backports hitting
kernels that are more widely used. There are a few more issues under
investigation, but these fixes are straight-forward and important, so no need
to delay them.

Please pull.

The following changes since commit b3810c5a2cc4a6665f7a65bed5393c75ce3f3aa2:

  x86/efistub: Clear decompressor BSS in native EFI entrypoint (2024-03-15 19:47:09 +0100)

EFI fixes for v6.9 #2

- Fix logic that is supposed to prevent placement of the kernel image
  below LOAD_PHYSICAL_ADDR
- Use the firmware stack in the EFI stub when running in mixed mode
- Clear BSS only once when using mixed mode
- Check efi.get_variable() function pointer for NULL before trying to
  call it
