But when doing so # missed to add the per-thread LDBAR update in the core_woken path of # the power9_idle_stop(). Patch fixes the same. # # Fixes: 10d91611f426 ("powerpc/64s: Reimplement book3s idle code in C") # Cc: stable@vger.kernel.org # v5.2+ # Signed-off-by: Athira Rajeev # Signed-off-by: Madhavan Srinivasan # Reviewed-by: Nicholas Piggin # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/20190702105836.26695-1-maddy@linux.vnet.ibm.com # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-ld --version # < git log --format=%s --max-count=1 f5a9e488d62360c91c5770bd55a0b40e419a71ce # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc40x_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- ppc40x_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc40x_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:194:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:65:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:331:21: note: 'pdeo' was declared here /kisskb/src/drivers/tty/serial/8250/8250_core.c: In function 'univ8250_release_irq': /kisskb/src/drivers/tty/serial/8250/8250_core.c:247:18: warning: 'i' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c:227:19: note: 'i' was declared here INFO: Uncompressed kernel (size 0x543588) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x543588) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x543588) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-5.2.0-rc2-gf5a9e488d623 Created: Sat Jul 13 01:03:43 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2670939 Bytes = 2608.34 KiB = 2.55 MiB Load Address: 00600000 Entry Point: 00601758 INFO: Uncompressed kernel (size 0x532f14) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x543588) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-5.2.0-rc2-gf5a9e488d623 Created: Sat Jul 13 01:03:44 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2671095 Bytes = 2608.49 KiB = 2.55 MiB Load Address: 00600000 Entry Point: 006019cc Image Name: Linux-5.2.0-rc2-gf5a9e488d623 Created: Sat Jul 13 01:03:44 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2639689 Bytes = 2577.82 KiB = 2.52 MiB Load Address: 00000000 Entry Point: 00000000 Completed OK # rm -rf /kisskb/build/powerpc-next_ppc40x_defconfig_powerpc-gcc4.6 # Build took: 0:00:42.986979
