2009-04-23OMAP2/3 GPTIMER: allow system tick GPTIMER to be changed in board-*.c filesPaul Walmsley
Add a function omap2_gp_clockevent_set_gptimer() for board-*.c files to use in .init_irq functions to configure the system tick GPTIMER. Practical choices at this point are GPTIMER1 or GPTIMER12. Both of these timers are in the WKUP powerdomain, and so are unaffected by chip power management. GPTIMER1 can use sys_clk as a source, for applications where a high-resolution timer is more important than power management. GPTIMER12 has the special property that it has the secure 32kHz oscillator as its source clock, which may be less prone to glitches than the off-chip 32kHz oscillator. But on HS devices, it may not be available for Linux use. It appears that most boards are fine with GPTIMER1, but BeagleBoard should use GPTIMER12 when using a 32KiHz timer source, due to hardware bugs in revisions B4 and below. Modify board-omap3beagle.c to use GPTIMER12. This patch originally used a Kbuild config option to select the GPTIMER, but was changed to allow this to be specified in board-*.c files, per Tony's request. Kalle Vallo <kalle.valo@nokia.com> found a bug in an earlier version of this patch - thanks Kalle. Tested on Beagle rev B4 ES2.1, with and without CONFIG_OMAP_32K_TIMER, and 3430SDP.

2009-04-23ARM: OMAP2/3: GPIO: do not attempt to wake-enableKevin Hilman
The GPIO IRQ enable/disable path attempts to also enable IRQ wake support for the parent GPIO bank IRQ as well. However, since there is no 'set_wake' hook for the bank IRQs, these calls will always fail. Also, since the enable will fail on the suspend path, the disable on the resume path will trigger unbalanced enable/disable warnings. This was discovered in the suspend/resume path on OMAP3/Beagle using the gpio-keys driver which disables/re-enables GPIO IRQ wakeups in the suspend/resume path.

2009-04-23ARM: OMAP: Fix for possible race condition in omap_free_dma()Santosh Shilimkar
Fix the possible race condition in omap_free_dma(). Function omap_free_dma() sets the dev_id = -1 and then accesses the channel afterwards to clear it. But setting the dev_id=-1 makes the channel available for allocation again. So it is possible someone else can grab it and results are unpredictable. To avod this DMA channle is cleared first and then the dev_id = -1 is set. Thanks to McNeil, Sean <sean.mcneil@ti.com> for ointing out this issue.

2009-04-21FRV: Fix the section attribute on UP DECLARE_PER_CPU()David Howells
In non-SMP mode, the variable section attribute specified by DECLARE_PER_CPU() does not agree with that specified by DEFINE_PER_CPU(). This means that architectures that have a small data section references relative to a base register may throw up linkage errors due to too great a displacement between where the base register points and the per-CPU variable. On FRV, the .h declaration says that the variable is in the .sdata section, but the .c definition says it's actually in the .data section. The linker throws up the following errors: kernel/built-in.o: In function `release_task': kernel/exit.c:78: relocation truncated to fit: R_FRV_GPREL12 against symbol `per_cpu__process_counts' defined in .data section in kernel/built-in.o kernel/exit.c:78: relocation truncated to fit: R_FRV_GPREL12 against symbol `per_cpu__process_counts' defined in .data section in kernel/built-in.o To fix this, DECLARE_PER_CPU() should simply apply the same section attribute as does DEFINE_PER_CPU(). However, this is made slightly more complex by virtue of the fact that there are several variants on DEFINE, so these need to be matched by variants on DECLARE.

2009-04-21frv: insert PCI root bus resources for the MB93090 devel motherboardDavid Howells
Insert PCI root bus resources for the FRV-based MB93090 development kit motherboard. This is required because the CPU's window onto the PCI bus address space is considerably smaller than the CPU's full address space and non-PCI devices lie outside of the PCI window that we might want to access. Without this patch, the PCI root bus uses the platform-level bus resources, and these are then confined to the PCI window, thus making platform_device_add() reject devices outside of this window.

2009-04-17x86, PAT: Remove page granularity tracking for vm_insert_pfn mapsPallipadi, Venkatesh
This change resolves the problem of too many single page entries in pat_memtype_list and "freeing invalid memtype" errors with i915, reported here: http://marc.info/?l=linux-kernel&m=123845244713183&w=2 Remove page level granularity track and untrack of vm_insert_pfn. memtype tracking at page granularity does not scale and cleaner approach would be for the driver to request a type for a bigger IO address range or PCI io memory range for that device, either at mmap time or driver init time and just use that type during vm_insert_pfn. This patch just removes the track/untrack of vm_insert_pfn. That means we will be in same state as 2.6.28, with respect to these APIs. Newer APIs for the drivers to request a memtype for a bigger region is coming soon.
