It looks like this will cause regressions unless you also apply:
21cdb6b56843 x86/mm: Page align the '_end' symbol to avoid pfn conversion bugs b61a76f8850d x86/efi: Map RAM into the identity page table for mixed mode 753b11ef8e92 x86/efi: Setup separate EFI page tables in kexec paths
and possibly also:
08914f436bdd x86/platform/UV: Bring back the call to map_low_mmrs in uv_system_init 683ad8092cd2 x86/efi: Fix 7-parameter efi_call()s 80e75596079f efi: Convert efi_call_virt() to efi_call_virt_pointer() d1be84a232e3 x86/uv: Update uv_bios_call() to use efi_call_virt_pointer()
Ugh, that's a mess. Yazen is the one who reported this patch, and 2 others, were needed to resolve an issue on their hardware.
Yazen, any thoughts here? Should I just revert the 3 patches, or do you also feel I need all 7 of these to ensure everything works properly?
thanks,
