Unused # bolted entries are stored with .esid=0 in the slb_shadow area, and # that value is now used directly as the RB input to slbmte, which means # the RB[52:63] index field is set to 0, which causes SLB entry 0 to be # cleared. # # Fix this by storing the index bits in the unused bolted entries, which # directs the slbmte to the right place. # # The SLB shadow area is also used by the hypervisor, but PAPR is okay # with that, from LoPAPR v1.1, 14.11.1.3 SLB Shadow Buffer: # # Note: SLB is filled sequentially starting at index 0 # from the shadow buffer ignoring the contents of # RB field bits 52-63 # # 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-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < git log --format=%s --max-count=1 0f52b3a00c789569d7ed822b5a6b30f59a8d4393 # < make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-next_44x_akebono_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- 44x/akebono_defconfig # make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-next_44x_akebono_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/net/Makefile:24: CC cannot link executables.
