2010-08-04CRIS: gpio: don't call copy_to_user()/copy_from_user() while holding spinlocksJesper Nilsson
copy_to_user()/copy_from_user() must not be used with spinlocks held. Move locks inside each case so we have better control of when the locks are held. Also, since we use spinlocks, we don't need to hold the BKL, so remove it. Reported-by: Kulikov Vasiliy <segooon@gmail.com> Signed-off-by: Jesper Nilsson <jesper.nilsson@axis.com>

2010-08-04cris: autoconvert trivial BKL users to private mutexJesper Nilsson
All these files use the big kernel lock in a trivial way to serialize their private file operations, typically resulting from an earlier semi-automatic pushdown from VFS. None of these drivers appears to want to lock against other code, and they all use the BKL as the top-level lock in their file operations, meaning that there is no lock-order inversion problem. Consequently, we can remove the BKL completely, replacing it with a per-file mutex in every case. Using a scripted approach means we can avoid typos. file=$1 name=$2 if grep -q lock_kernel ${file} ; then if grep -q 'include.*linux.mutex.h' ${file} ; then sed -i '/include.*<linux\/smp_lock.h>/d' ${file} else sed -i 's/include.*<linux\/smp_lock.h>.*$/include <linux\/mutex.h>/g' ${file} fi sed -i ${file} \ -e "/^#include.*linux.mutex.h/,$ { 1,/^\(static\|int\|long\)/ { /^\(static\|int\|long\)/istatic DEFINE_MUTEX(${name}_mutex); } }" \ -e "s/\(un\)*lock_kernel\>[ ]*()/mutex_\1lock(\&${name}_mutex)/g" \ -e '/[ ]*cycle_kernel_lock();/d' else sed -i -e '/include.*\<smp_lock.h\>/d' ${file} \ -e '/cycle_kernel_lock()/d' fi Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Jesper Nilsson <jesper.nilsson@axis.com>

2010-08-04CRIS: invoke oom-killer from page faultJesper Nilsson

2010-08-04CRIS: GENERIC_TIME fixesJesper Nilsson
GENERIC_TIME was not functional for CRIS, giving random backward time jumps. For CRISv32 implement a new clocksource using the free running counter and ditch the arch_gettimeoffset. The random time jumps still existed, but turned out to be the write_seqlock which was missing around our do_timer() call. So switch over to GENERIC_TIME using the clocksource for CRISv32. CRISv10 doesn't have the free running counter needed for the clocksource trick, but we can still use GENERIC_TIME with arch_gettimeoffset. Unfortunately, there were problems in using the prescaler register to timer0 for the gettimeoffset calculation, so it is now ignored, making our resolution worse by the tune of 40usec (0.4%) worst case. At the same time, clean up some formatting and use NSEC_PER_SEC instead of 1000000000. Signed-off-by: Jesper Nilsson <jesper.nilsson@axis.com>
2010-07-27time: Kill off CONFIG_GENERIC_TIMEJohn Stultz
Now that all arches have been converted over to use generic time via clocksources or arch_gettimeoffset(), we can remove the GENERIC_TIME config option and simplify the generic code.

2010-06-09arch: Implement local64_tPeter Zijlstra
On 64bit, local_t is of size long, and thus we make local64_t an alias. On 32bit, we fall back to atomic64_t. (architecture can provide optimized 32-bit version) (This new facility is to be used by perf events optimizations.)
