Subject: kbuild: use -fmacro-prefix-map for .S sources
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a716bd7432106aed82a751409d7be851a23022ac;p=linux.git

kbuild: use -fmacro-prefix-map for .S sources

Follow-up to commit a73619a845d5 ("kbuild: use -fmacro-prefix-map to
make __FILE__ a relative path"). Assembler sources also use __FILE__
macro so this flag should be also applied to those sources.
