This patch fixes that. # # Without this patch the SLB rebolt code overwirtes the 1st entry of # kernel linear mapping and causes SLB recovery to fail. # # Fixes: e7e81847478b ("powerpc/64s: move machine check SLB flushing to mm/slb.c") # Signed-off-by: Mahesh Salgaonkar <mahesh@linux.vnet.ibm.com> # Signed-off-by: Nicholas Piggin <npiggin@gmail.com> # Reviewed-by: Nicholas Piggin <npiggin@gmail.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < git log --format=%s --max-count=1 7312bd0c205dc9e6e30128ef9243d7bc8ba1187d # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_allmodconfig+4K_PAGES_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n CONFIG_MODULE_SIG=n CONFIG_SAMPLES=n CONFIG_PPC_4K_PAGES=y CONFIG_PPC_64K_PAGES=n # yes \n \| make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_allmodconfig+4K_PAGES_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- oldconfig yes: standard output: Broken pipe yes: write error # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_allmodconfig+4K_PAGES_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/net/Makefile:24: CC cannot link executables.
