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 120 ARCH=powerpc O=/kisskb/build/powerpc-next_83xx_mpc8313_rdb_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- 83xx/mpc8313_rdb_defconfig # make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-next_83xx_mpc8313_rdb_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/drivers/tty/serial/8250/8250_core.c: In function 'univ8250_release_irq': /kisskb/src/drivers/tty/serial/8250/8250_core.c:251:18: warning: 'i' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c:231:19: note: 'i' was declared here INFO: Uncompressed kernel (size 0x587c2c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-4.16.0-rc4-g95edc4d Created: Tue Apr 10 04:40:32 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2790813 Bytes = 2725.40 kB = 2.66 MB Load Address: 00000000 Entry Point: 00000000 Completed OK # rm -rf /kisskb/build/powerpc-next_83xx_mpc8313_rdb_defconfig_powerpc # Build took: 0:00:23.603700
