Hi all,
Today's linux-next merge of the tip tree got a conflict in:
drivers/firmware/efi/arm-init.c
between commits:
500899c2cc3e ("efi: ARM/arm64: ignore DT memory nodes instead of removing them")
7464b6e3a5fb ("efi: ARM: avoid warning about phys_addr_t cast")
from the arm64 tree and commits:
78ce248faa3c ("efi: Iterate over efi.memmap in for_each_efi_memory_desc()")
884f4f66ffd6 ("efi: Remove global 'memmap' EFI memory map")
from the tip tree.
I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging. You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.
