2006-06-20[ARM] 3599/1: AT91RM9200 remove global variablesAndrew Victor
Patch from Andrew Victor This patch removes some now unnecessary global variables - at91_master_clock, at91_serial_map, at91_console_port. Signed-off-by: Andrew Victor <andrew@sanpeople.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-06-20[ARM] 3607/1: AT91RM9200 misc fixesAndrew Victor
Patch from Andrew Victor This final patch includes some general fixes. 1. Link in pm.o if CONFIG_PM is enabled. [Should have been included in patch 3605/1]. 2. Use __raw_readl()/__raw_writel() when accessing System Peripheral registers. 3. Removed some unnecessary includes Signed-off-by: Andrew Victor <andrew@sanpeople.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-06-20[ARM] 3605/1: AT91RM9200 Power ManagementAndrew Victor
Patch from Andrew Victor This patch adds the core Power Management support for the AT91RM9200 processor. It will support suspend-to-RAM and standby modes. The suspend-to-RAM functionality is not 100% complete. The code that needs to be execute from the internal SRAM to restore the system is outstanding. For now we just fall through to Standby mode. The AT91-specific at91_suspend_entering_slow_clock() function will eventually be replaced by clk_must_disable() once that functionality is added to mainline clock API. Patch from David Brownell.

2006-06-08[PATCH] elevator switching raceJens Axboe
There's a race between shutting down one io scheduler and firing up the next, in which a new io could enter and cause the io scheduler to be invoked with bad or NULL data. To fix this, we need to maintain the queue lock for a bit longer. Unfortunately we cannot do that, since the elevator init requires to be run without the lock held. This isn't easily fixable, without also changing the mempool API. So split the initialization into two parts, and alloc-init operation and an attach operation. Then we can preallocate the io scheduler and related structures, and run the attach inside the lock after we detach the old one. This patch has survived 30 minutes of 1 second io scheduler switching with a very busy io load. Signed-off-by: Jens Axboe <axboe@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2006-06-05[PATCH] alpha: SMP IRQ routing fixIvan Kokshaysky
From: Ivan Kokshaysky <ink@jurassic.park.msu.ru> After removal of fixup_cpu_present_map() function Alpha ended up with an empty cpu_present_map, so secondary CPUs on SMP systems are not being started. Worse, on some platforms we route interrupts to secondary CPUs using cpu_possible_map which is still populated properly. As a result, these interrupts go nowhere so the machines like DP264 aren't able to boot even with a primary CPU. Fixed basically by s/cpu_present_mask/cpu_present_map/.
