Subject: [PATCH] sparc: vdso: clean-up vdso Makefile
Date: Wed, 12 Sep 2018 12:39:13 +0900 [thread overview]
Message-ID: <1536723553-21287-1-git-send-email-yamada.masahiro@socionext.com> (raw)
arch/sparc/vdso/Makefile is a replica of arch/x86/entry/vdso/Makefile.
Clean-up the Makefile in the same way as I did for x86:
- Remove unnecessary export
- Put the generated linker script to $(obj)/ instead of $(src)/
- Simplify cmd_vdso2c
The corresponding x86 commits are:
- 61615faf0a89 ("x86/build/vdso: Remove unnecessary export in Makefile")
- 1742ed2088cc ("x86/build/vdso: Put generated linker scripts to $(obj)/")
- c5fcdbf15523 ("x86/build/vdso: Simplify 'cmd_vdso2c'")
