When kernel needs to write to RW pages, the associated # segment register is then changed to Ks 0 in order to allow write # access to the kernel. # # In order to avoid having the read all segment registers when # locking/unlocking the access, some data is kept in the thread_struct # and saved on stack on exceptions. The field identifies both the # first unlocked segment and the first segment following the last # unlocked one. When no segment is unlocked, it contains value 0. # # Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 cc0bb290a0dabcdbc422fd4721e000ea115a5beb # < make -s -j 8 ARCH=powerpc O=/kisskb/build/chleroy_pmac32_defconfig+kexec_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- pmac32_defconfig # Added to kconfig configs/2006/11/29/pmac32_defconfigkexec # yes \n \| make -s -j 8 ARCH=powerpc O=/kisskb/build/chleroy_pmac32_defconfig+kexec_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- oldconfig yes: standard output: Broken pipe # make -s -j 8 ARCH=powerpc O=/kisskb/build/chleroy_pmac32_defconfig+kexec_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- In file included from /kisskb/src/sound/ppc/pmac.h:25:0, from /kisskb/src/sound/ppc/awacs.c:29: /kisskb/src/sound/ppc/awacs.c: In function 'snd_pmac_awacs_init': /kisskb/src/include/sound/control.h:223:9: warning: 'speaker_vol' may be used uninitialized in this function [-Wmaybe-uninitialized] return _snd_ctl_add_slave(master, slave, 0); ^ /kisskb/src/sound/ppc/awacs.c:886:36: note: 'speaker_vol' was declared here struct snd_kcontrol master_vol, speaker_vol; ^ /kisskb/src/kernel/futex.c: In function 'do_futex': /kisskb/src/kernel/futex.c:1662:17: warning: 'oldval' may be used uninitialized in this function [-Wmaybe-uninitialized] return oldval == cmparg; ^ /kisskb/src/kernel/futex.c:1637:6: note: 'oldval' was declared here int oldval, ret; ^ INFO: Uncompressed kernel (size 0x8f02d0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x900000) Completed OK # rm -rf /kisskb/build/chleroy_pmac32_defconfig+kexec_powerpc-gcc5 # Build took: 0:02:13.174245
