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/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 e13e7cd4c0c1cc9984d9b6a8663e10d76b53f2aa # < make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_83xx_mpc832x_mds_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- 83xx/mpc832x_mds_defconfig # make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_83xx_mpc832x_mds_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/kernel/futex.c: In function 'do_futex': /kisskb/src/kernel/futex.c:1658:17: warning: 'oldval' may be used uninitialized in this function [-Wmaybe-uninitialized] return oldval == cmparg; ^ /kisskb/src/kernel/futex.c:1633:6: note: 'oldval' was declared here int oldval, ret; ^ INFO: Uncompressed kernel (size 0x52663c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x515f24) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-5.2.0-rc2-ge13e7cd4c0c1 Created: Wed Jun 26 00:24:37 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2617632 Bytes = 2556.28 KiB = 2.50 MiB Load Address: 00600000 Entry Point: 00600294 Image Name: Linux-5.2.0-rc2-ge13e7cd4c0c1 Created: Wed Jun 26 00:24:37 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2588222 Bytes = 2527.56 KiB = 2.47 MiB Load Address: 00000000 Entry Point: 00000000 Completed OK # rm -rf /kisskb/build/powerpc-fixes_83xx_mpc832x_mds_defconfig_powerpc-gcc5 # Build took: 0:00:23.369979
