mn10300/misalignment: Use SIGSEGV SEGV_MAPERR to report a failed user copy

2018-01-12T20:23:36+00:00

Setting si_code to 0 is the same a setting si_code to SI_USER which is definitely not correct. With si_code set to SI_USER si_pid and si_uid will be copied to userspace instead of si_addr. Which is very wrong. So fix this by using a sensible si_code (SEGV_MAPERR) for this failure.

mn10300: migrate exception table users off module.h and onto extable.h

2017-01-24T17:41:46+00:00

These files were only including module.h for exception table related functions. We've now separated that content out into its own file "extable.h" so now move over to that and avoid all the extra header content in module.h that we don't really need to compile these files.

Replace with globally

2016-12-24T19:46:01+00:00

This was entirely automated, using the script by Al: PATT='^[[:blank:]]*#[[:blank:]]*include[[:blank:]]*' sed -i -e "s!$PATT!#include !" \ $(git grep -l "$PATT"|grep -v ^include/linux/uaccess.h) to do the replacement at the end of the merge window.

mn10300: add cc clobbers to asm statements

2010-01-11T17:34:10+00:00

gcc 4.2.1 for MN10300 is more agressive than the older gcc in reordering/moving other insns between an insn that sets flags and an insn that uses those flags. This leads to trouble with asm statements which are missing an explicit "cc" clobber. This patch adds the explicit "cc" clobber to asm statements which do indeed clobber the condition flags.

headers: smp_lock.h redux

2009-07-12T19:22:34+00:00

* Remove smp_lock.h from files which don't need it (including some headers!) * Add smp_lock.h to files which do need it * Make smp_lock.h include conditional in hardirq.h It's needed only for one kernel_locked() usage which is under CONFIG_PREEMPT This will make hardirq.h inclusion cheaper for every PREEMPT=n config (which includes allmodconfig/allyesconfig, BTW) Signed-off-by: Alexey Dobriyan Signed-off-by: Linus Torvalds

MN10300: Don't do misalignment handling for userspace

Don't do misalignment handling for userspace misalignment faults: just generate an appropriate SIGBUS instead. Signed-off-by: David Howells Signed-off-by: Linus Torvalds
