* SLUB: CONFIG_LARGE_ALLOCS must consider MAX_ORDER limitChristoph Lameter2007-05-15
| | | | | | | | | | | Take MAX_ORDER into consideration when determining KMALLOC_SHIFT_HIGH. Otherwise we may run into a situation where we attempt to create general slabs larger than MAX_ORDER.

* Remove cpu hotplug defines for __INIT & __INITDATAPrarit Bhargava2007-05-15
| | | | | | | | | | | | | | | | | | After examining what was checked in and the code base I discovered that most of 86c0baf123e474b6eb404798926ecf62b426bf3a wasn't necessary anymore.... So here's a patch that reverts the last part of that changeset: Revert part of 86c0baf123e474b6eb404798926ecf62b426bf3a. The kernel has moved forward to a state where the original change is not necessary. After porting forward, this final version of the patch was applied and broke non-x86 architectures.

* alpha: fix hard_smp_processor_id compile errorSimon Horman2007-05-15

* nommu: add ioremap_page_range()Paul Mundt2007-05-15
| | | | | | | | | | | | | | | | lib/ioremap.c is presently only built in if CONFIG_MMU is set. While this is reasonable, platforms that support both CONFIG_MMU=y or n need to be able to call in to this regardless. As none of the current nommu platforms do anything special with ioremap(), we assume that it's always successful. This fixes the SH-4 build with CONFIG_MMU=n.

* fix epoll single pass code and add wait-exclusive flagDavide Libenzi2007-05-15
| | | | | | | | | | | | | | | Fixes the epoll single pass code. During the unlocked event delivery (to userspace) code, the poll callback can re-issue new events, and we must receive them correctly. Since we loop in a lockless fashion, we want to be O(nready), and we don't want to flash on/off the spinlock for every event, we have the poll callback to use a secondary list to queue events while we're inside the event delivery loop. The rw_semaphore has been turned into a mutex. This patch also adds the wait-exclusive flag, as suggested by Davi Arnaut.

* Revert "ipmi: add new IPMI nmi watchdog handling"Linus Torvalds2007-05-14
| | | | | | | | | | | | | | | | | | This reverts commit f64da958dfc83335de1d2bef9d3868f30feb4e53. Andi Kleen is unhappy with the changes, and they really do not seem worth it. IPMI could use DIE_NMI_IPI instead of the new callback, even though that ends up having its own set of problems too, mainly because the IPMI code cannot really know the NMI was from IPMI or not. Manually fix up conflicts in arch/x86_64/kernel/traps.c and drivers/char/ipmi/ipmi_watchdog.c.

We only use the dir argument to update the policy count for that direction. Since the user can supply any value for dir, this can corrupt our policy count. I know this is the problem because a few days ago I was deleting policies by hand using indicies and accidentally typed in the wrong direction. It still deleted the policy and at the time I thought that was cool. In retrospect it isn't such a good idea :) I decided against letting it delete the policy anyway just in case we ever remove the connection between indicies and direction.
