If the virtual mode handler is # reached, it will lock and restore the AMR. # # Fixes: 890274c2dc4c0 ("powerpc/64s: Implement KUAP for Radix MMU") # Cc: Russell Currey <ruscur@russell.cc> # 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 # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-ld --version # < git log --format=%s --max-count=1 e13e7cd4c0c1cc9984d9b6a8663e10d76b53f2aa # < make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_powerpc-allnoconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- allnoconfig # make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_powerpc-allnoconfig_powerpc-gcc4.6 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:194:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] Completed OK # rm -rf /kisskb/build/powerpc-fixes_powerpc-allnoconfig_powerpc-gcc4.6 # Build took: 0:00:08.896252
