In a freshly extracted 2.6.23 tarball, I applied the 4 uml-*.patch files from stable-queue/review-2.6.23-2 in sequence (all applied cleanly), and then did the following: cat > mini.conf << EOF && CONFIG_BINFMT_ELF=y CONFIG_HOSTFS=y CONFIG_LBD=y CONFIG_BLK_DEV=y CONFIG_BLK_DEV_LOOP=y CONFIG_STDERR_CONSOLE=y CONFIG_UNIX98_PTYS=y CONFIG_EXT2_FS=y EOF make ARCH=um allnoconfig KCONFIG_ALLCONFIG=mini.conf Then I did: make -j 2 ARCH=um And it still breaks: CC arch/um/kernel/smp.o In file included from include/asm/arch/tlb.h:11, from include/asm/tlb.h:4, from arch/um/kernel/smp.c:8: include/asm-generic/tlb.h: In function ‘tlb_flush_mmu’: include/asm-generic/tlb.h:76: error: implicit declaration of function ‘release_pages’ include/asm-generic/tlb.h: In function ‘tlb_remove_page’: include/asm-generic/tlb.h:105: error: implicit declaration of function ‘page_cache_release’ make[1]: *** [arch/um/kernel/smp.o] Error 1 make: *** [arch/um/kernel] Error 2 make: *** Waiting for unfinished jobs....
