This # leads save_nvgprs to skip saving them, and subsequent functions and # return from interrupt will think they are saved. # # This causes kernel branch-to-garbage debugging to not have correct # registers, can also cause userspace to have its registers clobbered # after a segfault. # # Fixes: f0f558b131 ("powerpc/mm: Preserve CFAR value on SLB miss caused by access to bogus address") # Cc: Paul Mackerras <paulus@ozlabs.org> # Signed-off-by: Nicholas Piggin <npiggin@gmail.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 9c1a41149230e5e2d48c8948943306b8c0c9f242 # < make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_gamecube_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- gamecube_defconfig # make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_gamecube_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/kernel/rcu/srcutree.c: In function 'init_srcu_struct_fields': /kisskb/src/kernel/rcu/srcutree.c:127:33: warning: 'levelspread[<Uc8c0>]' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/kernel/rcu/srcutree.c:94:6: note: 'levelspread[<Uc8c0>]' 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] INFO: Uncompressed kernel (size 0x67e038) overlaps the address of the wrapper(0x600000) INFO: Fixing the link_address of wrapper to (0x700000) Completed OK # rm -rf /kisskb/build/powerpc-fixes_gamecube_defconfig_powerpc # Build took: 0:00:25.189744
