In the rare case where kernel find all the # 8 primary hash slot occupied by bolted entries, this can result in hash page # table insert failure for bolted entries. Avoid this by using the secondary hash # group. # # This is different from what kernel does for the non-bolted mapping. With # non-bolted entries kernel will try secondary before removing an existing entry # from hash page table group. With bolted prefer primary hash group and hence # try to insert the page table entry by removing a slot from primary before trying # the secondary hash group. # # Signed-off-by: Aneesh Kumar K.V # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/20191024093542.29777-3-aneesh.kumar@linux.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 d78d5dace5398b542fd5a21b50db6e88ce7d392e # < make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc5200_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- mpc5200_defconfig # make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc5200_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:204:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/base/regmap/regmap.c: In function 'regmap_raw_read': /kisskb/src/drivers/base/regmap/regmap.c:2591:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/base/regmap/regmap.c: In function '_regmap_raw_write': /kisskb/src/drivers/base/regmap/regmap.c:1852:6: warning: 'ret' 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:338:21: note: 'pdeo' was declared here /kisskb/src/sound/soc/soc-pcm.c: In function 'soc_pcm_trigger': /kisskb/src/sound/soc/soc-pcm.c:1074:5: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/sound/soc/soc-pcm.c: In function 'soc_pcm_bespoke_trigger': /kisskb/src/sound/soc/soc-pcm.c:1092:9: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/usb/core/devio.c: In function 'async_completed': /kisskb/src/drivers/usb/core/devio.c:625:23: warning: 'errno' may be used uninitialized in this function [-Wuninitialized] INFO: Uncompressed kernel (size 0x6f5754) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) INFO: Uncompressed kernel (size 0x6f5754) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) INFO: Uncompressed kernel (size 0x6f5754) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) INFO: Uncompressed kernel (size 0x6e50d8) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) Image Name: Linux-5.4.0-rc2-gd78d5dace539 Created: Mon Oct 28 22:30:42 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3519576 Bytes = 3437.09 KiB = 3.36 MiB Load Address: 00700000 Entry Point: 00700278 Image Name: Linux-5.4.0-rc2-gd78d5dace539 Created: Mon Oct 28 22:30:42 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3519806 Bytes = 3437.31 KiB = 3.36 MiB Load Address: 00700000 Entry Point: 00700278 Image Name: Linux-5.4.0-rc2-gd78d5dace539 Created: Mon Oct 28 22:30:42 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3519829 Bytes = 3437.33 KiB = 3.36 MiB Load Address: 00700000 Entry Point: 00700278 Image Name: Linux-5.4.0-rc2-gd78d5dace539 Created: Mon Oct 28 22:30:42 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3489943 Bytes = 3408.15 KiB = 3.33 MiB Load Address: 00000000 Entry Point: 00000000 Completed OK # rm -rf /kisskb/build/powerpc-next_mpc5200_defconfig_powerpc-gcc4.6 # Build took: 0:01:07.670949
