It's an entirely # historical artifact, and long long long ago used to actually read the # segment selector valueof '%ds' on x86. # # Which in the kernel is always KERNEL_DS. # # Inspired by a patch from Jann Horn that just did this for a very small # subset of users (the ones in fs/), along with Al who suggested a script. # I then just took it to the logical extreme and removed all the remaining # gunk. # # Roughly scripted with # # git grep -l '(get_ds())' -- :^tools/ \| xargs sed -i 's/(get_ds())/(KERNEL_DS)/' # git grep -lw 'get_ds' -- :^tools/ \| xargs sed -i '/^#define get_ds()/d' # # plus manual fixups to remove a few unusual usage patterns, the couple of # inline function cases and to fix up a comment that had become stale. # # The 'get_ds()' function remains in an x86 kvm selftest, since in user # space it actually does something relevant. # # Inspired-by: Jann Horn <jannh@google.com> # Inspired-by: Al Viro <viro@zeniv.linux.org.uk> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-gcc --version # < /opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-ld --version # < git log --format=%s --max-count=1 736706bee3298208343a76096370e4f6a5c55915 # < make -s -j 80 ARCH=arm64 O=/kisskb/build/linus_arm64-allmodconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- allmodconfig # make -s -j 80 ARCH=arm64 O=/kisskb/build/linus_arm64-allmodconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- arch/arm64/Makefile:27: ld does not support --fix-cortex-a53-843419; kernel may be susceptible to erratum arch/arm64/Makefile:40: LSE atomics not supported by binutils In file included from /kisskb/src/include/asm-generic/bug.h:18:0, from /kisskb/src/arch/arm64/include/asm/bug.h:37, from /kisskb/src/include/linux/bug.h:5, from /kisskb/src/include/linux/mmdebug.h:5, from /kisskb/src/include/linux/mm.h:9, from /kisskb/src/drivers/dma/imx-dma.c:14: /kisskb/src/drivers/dma/imx-dma.c: In function 'imxdma_sg_next': /kisskb/src/include/linux/kernel.h:846:29: warning: comparison of distinct pointer types lacks a cast (!!(sizeof((typeof(x) )1 == (typeof(y) )1))) ^ /kisskb/src/include/linux/kernel.h:860:4: note: in expansion of macro '__typecheck' (__typecheck(x, y) && __no_side_effects(x, y)) ^ /kisskb/src/include/linux/kernel.h:870:24: note: in expansion of macro '__safe_cmp' __builtin_choose_expr(__safe_cmp(x, y), \ ^ /kisskb/src/include/linux/kernel.h:879:19: note: in expansion of macro '__careful_cmp' #define min(x, y) __careful_cmp(x, y, <) ^ /kisskb/src/drivers/dma/imx-dma.c:288:8: note: in expansion of macro 'min' now = min(d->len, sg_dma_len(sg)); ^ In file included from /kisskb/src/include/linux/rwsem.h:16:0, from /kisskb/src/include/linux/notifier.h:15, from /kisskb/src/include/linux/clk.h:17, from /kisskb/src/drivers/tty/serial/sh-sci.c:24: /kisskb/src/drivers/tty/serial/sh-sci.c: In function 'sci_submit_rx': /kisskb/src/include/linux/spinlock.h:279:3: warning: 'flags' may be used uninitialized in this function [-Wmaybe-uninitialized] _raw_spin_unlock_irqrestore(lock, flags); \ ^ /kisskb/src/drivers/tty/serial/sh-sci.c:1338:16: note: 'flags' was declared here unsigned long flags; ^ Completed OK # rm -rf /kisskb/build/linus_arm64-allmodconfig_arm64-gcc5.4 # Build took: 0:15:20.286204
