A single larx/stcx. works fine, no need for the less # efficient cmpxchg sequence. # # Then remove the memory barriers from the operation. There is a # requirement for TLB flushing to load mm_cpumask after the store # that reduces pte permissions, which is moved into the TLB flush # code. # # 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 c8635bc26fc137c218cba3b48a834a667e3ac790 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_40x_obs600_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- 40x/obs600_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_40x_obs600_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/arch/powerpc/mm/fault.c: In function '__do_page_fault': /kisskb/src/arch/powerpc/mm/fault.c:520:3: error: implicit declaration of function 'fault_in_pages_readable' [-Werror=implicit-function-declaration] cc1: all warnings being treated as errors /kisskb/src/scripts/Makefile.build:312: recipe for target 'arch/powerpc/mm/fault.o' failed make[2]: * [arch/powerpc/mm/fault.o] Error 1 make[2]: * Waiting for unfinished jobs.... /kisskb/src/Makefile:1060: recipe for target 'arch/powerpc/mm' failed make[1]: * [arch/powerpc/mm] Error 2 make[1]: * Waiting for unfinished jobs.... /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] Makefile:146: recipe for target 'sub-make' failed make: * [sub-make] Error 2 Command 'make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_40x_obs600_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/powerpc-next_40x_obs600_defconfig_powerpc # Build took: 0:00:10.039541
