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 10 ARCH=powerpc O=/kisskb/build/chleroy_ps3_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ps3_defconfig # make -s -j 10 ARCH=powerpc O=/kisskb/build/chleroy_ps3_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- WARNING: modpost: Found 1 section mismatch(es).
