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/i386-linux/bin/i386-linux-gcc --version # < git log --format=%s --max-count=1 95edc4da89c32317b6ce22c90cb4793d3646565d # < make -s -j 48 ARCH=i386 O=/kisskb/build/powerpc-next_i386_defconfig_i386 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/i386-linux/bin/i386-linux- i386_defconfig # make -s -j 48 ARCH=i386 O=/kisskb/build/powerpc-next_i386_defconfig_i386 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/i386-linux/bin/i386-linux- CONFIG_CC_STACKPROTECTOR_AUTO: -fstack-protector available but compiler is broken: disabling /kisskb/src/arch/x86/kernel/e820.c: In function 'e820__setup_pci_gap': /kisskb/src/arch/x86/kernel/e820.c:652:2: warning: 'gapstart' may be used uninitialized in this function [-Wuninitialized] In file included from /kisskb/src/include/linux/pkeys.h:6:0, from /kisskb/src/arch/x86/kernel/fpu/core.c:15: /kisskb/src/arch/x86/include/asm/mmu_context.h: In function 'arch_vma_access_permitted': /kisskb/src/arch/x86/include/asm/mmu_context.h:333:2: error: implicit declaration of function 'vma_pkey' [-Werror=implicit-function-declaration] cc1: some warnings being treated as errors /kisskb/src/scripts/Makefile.build:324: recipe for target 'arch/x86/kernel/fpu/core.o' failed make[4]: * [arch/x86/kernel/fpu/core.o] Error 1 /kisskb/src/scripts/Makefile.build:583: recipe for target 'arch/x86/kernel/fpu' failed make[3]: * [arch/x86/kernel/fpu] Error 2 make[3]: * Waiting for unfinished jobs.... /kisskb/src/arch/x86/kernel/apic/io_apic.c: In function 'mp_map_pin_to_irq': /kisskb/src/arch/x86/kernel/apic/io_apic.c:1033:6: warning: 'irq' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/kernel/rcu/srcutree.c: In function 'init_srcu_struct_fields': /kisskb/src/kernel/rcu/srcutree.c:146:32: warning: 'levelspread[<U5780>]' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/kernel/rcu/srcutree.c:94:6: note: 'levelspread[<U5780>]' was declared here /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/sound/hda/hdac_regmap.c: In function 'hda_reg_write': /kisskb/src/sound/hda/hdac_regmap.c:282:16: warning: 'err' 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] In file included from /kisskb/src/include/linux/pkeys.h:6:0, from /kisskb/src/mm/mprotect.c:27: /kisskb/src/arch/x86/include/asm/mmu_context.h: In function 'arch_vma_access_permitted': /kisskb/src/arch/x86/include/asm/mmu_context.h:333:2: error: implicit declaration of function 'vma_pkey' [-Werror=implicit-function-declaration] cc1: some warnings being treated as errors /kisskb/src/scripts/Makefile.build:324: recipe for target 'mm/mprotect.o' failed make[2]: * [mm/mprotect.o] Error 1 make[2]: * Waiting for unfinished jobs....
