Subject[PATCH] MIPS: vmlinuz: Fix compiler intrinsics location and build directly
Date
Since commit "MIPS: use generic GCC library routines from lib/", MIPS
now uses the generic lib/ashldi3.c, but bswapsi.c still comes from
arch/mips/lib. The rules for including these into vmlinuz need updating
to reflect these locations.
Both objects need to be built with different CFLAGS for inclusion to
vmlinuz rather than simply including the object built for the main
kernel image. But the copy of the source C file can be avoided by simply
calling cmd,cc_o_c to build the object from the source directly. This
also removes the need for the .gitignore file to ignore the copied
files, and the extra-y rule to clean them.
