2010-08-04CRIS: gpio: don't call copy_to_user()/copy_from_user() while holding spinlocksJesper Nilsson1-32/+48
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 Nilsson4-12/+6
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: GENERIC_TIME fixesJesper Nilsson4-106/+45
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>

Fix the logic while writing new date/time to the chip. The driver incorrectly wrote back register values to different registers and even with wrong mask. The patch adds clearing of the VLF register, which should be cleared if all date/time values are set.

2010-07-28dynamic debug: move ddebug_remove_module() down into free_module()Jason Baron1-1/+3
The command echo "file ec.c +p" >/sys/kernel/debug/dynamic_debug/control causes an oops. Move the call to ddebug_remove_module() down into free_module(). In this way it should be called from all error paths. Currently, we are missing the remove if the module init routine fails.
