This change moves enabling these interrupts # earlier covering the function get_user(). While at this, lets check # for kernel mode and crash as this interrupt should not have been # triggered from the kernel context. # # Signed-off-by: Anshuman Khandual <khandual@linux.vnet.ibm.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < git log --format=%s --max-count=1 95edc4da89c32317b6ce22c90cb4793d3646565d # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc885_ads_defconfig+HUGETLB_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- mpc885_ads_defconfig # Added to kconfig CONFIG_HUGETLBFS=y # yes \n \| make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc885_ads_defconfig+HUGETLB_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- oldconfig yes: standard output: Broken pipe yes: write error # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc885_ads_defconfig+HUGETLB_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/arch/powerpc/mm/slice.c: In function 'slice_get_unmapped_area': /kisskb/src/arch/powerpc/mm/slice.c:655:2: error: implicit declaration of function 'need_extra_context' [-Werror=implicit-function-declaration] /kisskb/src/arch/powerpc/mm/slice.c:656:3: error: implicit declaration of function 'alloc_extended_context' [-Werror=implicit-function-declaration] cc1: all warnings being treated as errors /kisskb/src/scripts/Makefile.build:324: recipe for target 'arch/powerpc/mm/slice.o' failed make[2]: * [arch/powerpc/mm/slice.o] Error 1 make[2]: * Waiting for unfinished jobs.... /kisskb/src/Makefile:1051: recipe for target 'arch/powerpc/mm' failed make[1]: * [arch/powerpc/mm] Error 2 make[1]: * Waiting for unfinished jobs.... /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:183:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/mm/hugetlb.c: In function 'alloc_pool_huge_page': /kisskb/src/mm/hugetlb.c:1439:5: warning: 'page' may be used uninitialized in this function [-Wuninitialized] make[1]: * wait: No child processes.
