Subject: [PATCH] kbuild: remove unused OBJSIZE
Date: Fri, 23 Oct 2020 13:57:32 +0200	[thread overview]
Message-ID: <patch.git-ef02981ce9bc.your-ad-here.call-01603453662-ext-3714@work.hours> (raw)

The "size" tool has been solely used by s390 to enforce .bss section usage
restrictions in early startup code. Since commit 980d5f9ab36b ("s390/boot:
enable .bss section for compressed kernel") and commit 2e83e0eb85ca
("s390: clean .bss before running uncompressed kernel") these restrictions
have been lifted for the decompressor and uncompressed kernel and the
size tool is now unused.

 Currently, the integrated assembler is disabled by default. You can pass
 ``LLVM_IAS=1`` to enable it.
