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 # Signed-off-by: Michael Ellerman # < /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 80 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc6xx_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- ppc6xx_defconfig # make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc6xx_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /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/kernel/cgroup/cgroup-v1.c: In function 'cgroup1_mount': /kisskb/src/kernel/cgroup/cgroup-v1.c:1268:20: warning: 'root' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/sound/ppc/awacs.c: In function 'snd_pmac_awacs_init': /kisskb/src/include/sound/control.h:220:2: warning: 'speaker_vol' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/sound/ppc/awacs.c:886:36: note: 'speaker_vol' was declared here /kisskb/src/drivers/dma-buf/reservation.c: In function 'reservation_object_add_shared_fence': /kisskb/src/drivers/dma-buf/reservation.c:225:6: warning: 'k' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/nfsd/nfs4xdr.c: In function 'nfsd4_encode_components_esc': /kisskb/src/fs/nfsd/nfs4xdr.c:2043:9: warning: 'str' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/input/joystick/analog.c:176:2: warning: #warning Precise timer not defined for this architecture.
