[PATCH 1/2] initramfs: fix clang build failure

From: Arnd Bergmann
Date: Fri Dec 04 2020 - 11:58:28 EST


From: Arnd Bergmann <arnd@xxxxxxxx>

There is only one function in init/initramfs.c that is in the .text
section, and it is marked __weak. When building with clang-12 and
the integrated assembler, this leads to a bug with recordmcount:

./scripts/recordmcount "init/initramfs.o"
Cannot find symbol for section 2: .text.
init/initramfs.o: failed

I'm not quite sure what exactly goes wrong, but I notice that this
function is only ever called from an __init function, and normally
inlined. Marking it __init as well is clearly correct and it
leads to recordmcount no longer complaining.
