I have run with both CONFIG_DEBUG_WX=y and #CONFIG_DEBUG_WX is not set.
But with both, "x86/efi: Build our own page table structures", the
kernel stops booting.

Unfortunately even with your below patch on top of c9f2a9a ("x86/efi:
Hoist page table switching code into efi_call_virt()" also fails to boot
with and without CONFIG_DEBUG_WX=y. I have added CONFIG_EFI_PGT_DUMP.

Here is the dmesg with CONFIG_DEBUG_WX=y. and CONFIG_EFI_PGT_DUMP=y on
top of c9f2a9a ("x86/efi: Hoist page table switching code into
efi_call_virt()" (just in case if it helps)
