Subject: [PATCH 5.4] powerpc: Use always instead of always-y in for crtsavres.o
Date: Fri, 26 Jan 2024 10:37:02 -0700	[thread overview]
Message-ID: <20240126-5-4-fix-lib-powerpc-backport-v1-1-2c110ed18b1d@kernel.org> (raw)

This commit is for linux-5.4.y only, it has no direct upstream
equivalent.

Prior to commit 5f2fb52fac15 ("kbuild: rename hostprogs-y/always to
hostprogs/always-y"), always-y did not exist, making the backport of
mainline commit 1b1e38002648 ("powerpc: add crtsavres.o to always-y
instead of extra-y") to linux-5.4.y as commit 245da9eebba0 ("powerpc:
add crtsavres.o to always-y instead of extra-y") incorrect, breaking the
build with linkers that need crtsavres.o:

  ld.lld: error: cannot open arch/powerpc/lib/crtsavres.o: No such file or directory

Backporting the aforementioned kbuild commit is not suitable for stable
due to its size and number of conflicts, so transform the always-y usage
to an equivalent form using always, which resolves the build issues.

Fixes: 245da9eebba0 ("powerpc: add crtsavres.o to always-y instead of extra-y")
