* writeback: make balance_dirty_pages() gradually back more offJens Axboe2009-09-211-1/+10
| | | | | | | | | Currently it just sleeps for a very short time, just 1 jiffy. If we keep looping in there, continually delay for a little longer of up to 100msec in total. That was the old limit for congestion wait. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
* writeback: don't use schedule_timeout() without setting runstateJens Axboe2009-09-211-1/+1

| | | | | | | | | | | | | | | | | | | | | | | | | | This patch converts the ar7_wdt driver to become a platform driver. The AR7 SoC specific identification and base register calculation is performed by the board code, therefore we no longer need to have access to ar7_chip_id. We also remove the reboot notifier code to use the platform shutdown method as Wim suggested. Signed-off-by: Florian Fainelli <florian@openwrt.org> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
| * [WATCHDOG] fix book E watchdog to take WDIOC_SETTIMEOUT arg in secondsChris Friesen2009-09-181-4/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The WDIOC_SETTIMEOUT argument is supposed to be a "seconds" value. However, the book E wdt currently treats it as a "period" which is interpreted in a board-specific way. This patch allows the user to pass in a "seconds" value and the driver will set the smallest timeout that is at least as large as specified by the user. It's been tested on e500 hardware and works as expected. The patch only modifies the CONFIG_FSL_BOOKE case, the CONFIG_4xx case is left unmodified as I don't have any hardware to test it on.

It's rather worrying that the code got submitted without a system call table, which evidently means that it got zero testing. Since the system call table has a different layout from the old one (which was modeled after the mips-o32 one), I also try to fix the entry.S path to use it. In the modified calling conventions, all system call arguments are passed as registers r4 through r9, instead of r4 through r7 plus stack for the fifth and sixth argument. This matches what other architectures to when they normally pass arguments on the stack. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
