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/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux-gcc --version # < /opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux-ld --version # < git log --format=%s --max-count=1 cc0bb290a0dabcdbc422fd4721e000ea115a5beb # < make -s -j 10 ARCH=mips O=/kisskb/build/chleroy_mips-defconfig_mipsel CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- defconfig # make -s -j 10 ARCH=mips O=/kisskb/build/chleroy_mips-defconfig_mipsel CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- FIT description: Linux 5.0.0-gcc0bb290a0da Created: Wed Mar 6 11:07:10 2019 Image 0 (kernel@0) Description: Linux 5.0.0-gcc0bb290a0da Created: Wed Mar 6 11:07:10 2019 Type: Kernel Image Compression: gzip compressed Data Size: 4504087 Bytes = 4398.52 KiB = 4.30 MiB Architecture: MIPS OS: Linux Load Address: 0x80100000 Entry Point: 0x80856370 Hash algo: sha1 Hash value: 1403842db038727b92c30e5db510b3a68e2b7468 Image 1 (fdt@boston) Description: img,boston Device Tree Created: Wed Mar 6 11:07:10 2019 Type: Flat Device Tree Compression: uncompressed Data Size: 3793 Bytes = 3.70 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 4799f50d688573234da6e9d7701234d394759ef4 Image 2 (fdt@ni169445) Description: NI 169445 device tree Created: Wed Mar 6 11:07:10 2019 Type: Flat Device Tree Compression: uncompressed Data Size: 1871 Bytes = 1.83 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 51b89b31605ee62038c8468c429af091dfc75ec7 Image 3 (fdt@xilfpga) Description: MIPSfpga (xilfpga) Device Tree Created: Wed Mar 6 11:07:10 2019 Type: Flat Device Tree Compression: uncompressed Data Size: 2708 Bytes = 2.64 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 63d058b780f65e22da30f0a183433765f1807f1d Default Configuration: 'conf@default' Configuration 0 (conf@default) Description: Generic Linux kernel Kernel: kernel@0 Configuration 1 (conf@boston) Description: Boston Linux kernel Kernel: kernel@0 FDT: fdt@boston Configuration 2 (conf@ni169445) Description: NI 169445 Linux Kernel Kernel: kernel@0 FDT: fdt@ni169445 Configuration 3 (conf@xilfpga) Description: MIPSfpga Linux kernel Kernel: kernel@0 FDT: fdt@xilfpga Completed OK # rm -rf /kisskb/build/chleroy_mips-defconfig_mipsel # Build took: 0:03:01.340720
