The patch titled Subject: mips: fix vdso32 build, again has been removed from the -mm tree. Its filename was mips-add-support-for-generic-vdso-fix.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Arnd Bergmann <arnd@xxxxxxxx> Subject: mips: fix vdso32 build, again The generic vdso support adds the same #if hack in two places, asm/vdso/vdso.h and config-n32-o32-env.c, but only the second is actually used. The result lacks the BUILD_VDSO32_64 macro, and that triggers a build error: ./include/linux/page-flags-layout.h:95:2: error: #error "Not enough bits in page flags" Move the macro into the other place, and remove the duplicated bits.
