But we haven't supported that in a long time, and these # days the 'type' argument is a purely historical artifact. # # A discussion about extending 'user_access_begin()' to do the range # checking resulted this patch, because there is no way we're going to # move the old VERIFY_xyz interface to that model. And it's best done at # the end of the merge window when I've done most of my merges, so let's # just get this done once and for all. # # This patch was mostly done with a sed-script, with manual fix-ups for # the cases that weren't of the trivial 'access_ok(VERIFY_xyz' form. # # There were a couple of notable cases: # # - csky still had the old "verify_area()" name as an alias. # # - the iter_iov code had magical hardcoded knowledge of the actual # values of VERIFY_{READ,WRITE} (not that they mattered, since nothing # really used it) # # - microblaze used the type argument for a debug printout # # but other than those oddities this should be a total no-op patch. # # I tried to fix up all architectures, did fairly extensive grepping for # access_ok() uses, and the changes are trivial, but I may have missed # something. Any missed conversion should be trivially fixable, though. # # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux-gcc --version # < /opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux-ld --version # < git log --format=%s --max-count=1 96d4f267e40f9509e8a66e2b39e8b95655617693 # < make -s -j 8 ARCH=sparc64 O=/kisskb/build/linus_sparc64-allmodconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_HAVE_FTRACE_MCOUNT_RECORD=n # Added to kconfig CONFIG_SAMPLES=n # Added to kconfig CONFIG_MODULE_SIG=n # yes \n \| make -s -j 8 ARCH=sparc64 O=/kisskb/build/linus_sparc64-allmodconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- oldconfig yes: standard output: Broken pipe # make -s -j 8 ARCH=sparc64 O=/kisskb/build/linus_sparc64-allmodconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- <stdin>:1336:2: warning: #warning syscall rseq not implemented [-Wcpp] /kisskb/src/drivers/input/joystick/analog.c:172:2: warning: #warning Precise timer not defined for this architecture.
