2006-06-30[PATCH] pcmcia: at91_cf suspend/resume/wakeupDavid Brownell
AT91 CF updates, mostly for power management: - Add suspend/resume methods to the AT91 CF driver, disabling non-wakeup IRQs during system suspend. The card detect IRQ serves as a wakeup event source. - Convert the driver to the more-current "platform_driver" style. So inserting or removing a CF card will wake the system, unless that has been disabled by updating the sysfs file; and there will be no more warnings about spurious IRQs during suspend/resume cycles.

Remove add_mc_to_global_list(). In next patch, this function will be reimplemented with different semantics. 1 Reimplement add_mc_to_global_list() with semantics that allow the caller to determine the ID number for a mem_ctl_info structure. Then modify edac_mc_add_mc() so that the caller specifies the ID number for the new mem_ctl_info structure. Platform-specific code should be able to assign the ID numbers in a platform-specific manner. For instance, on Opteron it makes sense to have the ID of the mem_ctl_info structure match the ID of the node that the memory controller belongs to. 2 Modify callers of edac_mc_add_mc() so they use the new semantics.

2006-06-30[PATCH] Light weight event countersChristoph Lameter
The remaining counters in page_state after the zoned VM counter patches have been applied are all just for show in /proc/vmstat. They have no essential function for the VM. We use a simple increment of per cpu variables. In order to avoid the most severe races we disable preempt. Preempt does not prevent the race between an increment and an interrupt handler incrementing the same statistics counter. However, that race is exceedingly rare, we may only loose one increment or so and there is no requirement (at least not in kernel) that the vm event counters have to be accurate. In the non preempt case this results in a simple increment for each counter. For many architectures this will be reduced by the compiler to a single instruction. This single instruction is atomic for i386 and x86_64. And therefore even the rare race condition in an interrupt is avoided for both architectures in most cases. The patchset also adds an off switch for embedded systems that allows a building of linux kernels without these counters. The implementation of these counters is through inline code that hopefully results in only a single instruction increment instruction being emitted (i386, x86_64) or in the increment being hidden though instruction concurrency (EPIC architectures such as ia64 can get that done). Benefits: - VM event counter operations usually reduce to a single inline instruction on i386 and x86_64. - No interrupt disable, only preempt disable for the preempt case. Preempt disable can also be avoided by moving the counter into a spinlock. - Handling is similar to zoned VM counters. - Simple and easily extendable. - Can be omitted to reduce memory use for embedded use.

2006-06-30[PATCH] Use Zoned VM Counters for NUMA statisticsChristoph Lameter
The numa statistics are really event counters. But they are per node and so we have had special treatment for these counters through additional fields on the pcp structure. We can now use the per zone nature of the zoned VM counters to realize these. This will shrink the size of the pcp structure on NUMA systems. We will have some room to add additional per zone counters that will all still fit in the same cacheline. Bits Prior pcp size Size after patch We can add ------------------------------------------------------------------ 64 128 bytes (16 words) 80 bytes (10 words) 48 32 76 bytes (19 words) 56 bytes (14 words) 8 (64 byte cacheline) 72 (128 byte) Remove the special statistics for numa and replace them with zoned vm counters. This has the side effect that global sums of these events now show up in /proc/vmstat. Also take the opportunity to move the zone_statistics() function from page_alloc.c into vmstat.c.

2006-06-30[PATCH] zoned vm counters: conversion of nr_unstable to per zone counterChristoph Lameter
Conversion of nr_unstable to a per zone counter We need to do some special modifications to the nfs code since there are multiple cases of disposition and we need to have a page ref for proper accounting. This converts the last critical page state of the VM and therefore we need to remove several functions that were depending on GET_PAGE_STATE_LAST in order to make the kernel compile again. We are only left with event type counters in page state.

2006-06-30[PATCH] zoned vm counters: conversion of nr_writeback to per zone counterChristoph Lameter
Conversion of nr_writeback to per zone counter. This removes the last page_state counter from arch/i386/mm/pgtable.c so we drop the page_state from there.
