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-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux-gcc --version # < git log --format=%s --max-count=1 c8635bc26fc137c218cba3b48a834a667e3ac790 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_allmodconfig+ppc64le_ppc64le CROSS_COMPILE=/opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux- allmodconfig # Added to kconfig CONFIG_CPU_LITTLE_ENDIAN=y # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # yes \n \| make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_allmodconfig+ppc64le_ppc64le CROSS_COMPILE=/opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux- oldconfig yes: standard output: Broken pipe yes: write error # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_allmodconfig+ppc64le_ppc64le CROSS_COMPILE=/opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux- In file included from /kisskb/src/include/linux/io.h:25:0, from /kisskb/src/include/linux/of_address.h:7, from /kisskb/src/drivers/ata/ahci_qoriq.c:18: /kisskb/src/drivers/ata/ahci_qoriq.c: In function 'ahci_qoriq_hardreset': /kisskb/src/arch/powerpc/include/asm/io.h:160:2: warning: 'px_is' may be used uninitialized in this function [-Wmaybe-uninitialized] __asm__ __volatile__("sync;"#insn"%U0%X0 %1,%0" \ ^ /kisskb/src/drivers/ata/ahci_qoriq.c:86:14: note: 'px_is' was declared here u32 px_cmd, px_is, px_val; ^ In file included from /kisskb/src/include/linux/io.h:25:0, from /kisskb/src/include/linux/of_address.h:7, from /kisskb/src/drivers/ata/ahci_qoriq.c:18: /kisskb/src/arch/powerpc/include/asm/io.h:160:2: warning: 'px_cmd' may be used uninitialized in this function [-Wmaybe-uninitialized] __asm__ __volatile__("sync;"#insn"%U0%X0 %1,%0" \ ^ /kisskb/src/drivers/ata/ahci_qoriq.c:86:6: note: 'px_cmd' was declared here u32 px_cmd, px_is, px_val; ^ WARNING: vmlinux.o(.text+0x3664): Section mismatch in reference from the variable __boot_from_prom to the function .init.text:prom_init() The function __boot_from_prom() references the function __init prom_init().
