2009-04-23davinci: major rework of clock, PLL, PSC infrastructureKevin Hilman
This is a significant rework of the low-level clock, PLL and Power Sleep Controller (PSC) implementation for the DaVinci family. The primary goal is to have better modeling if the hardware clocks and features with the aim of DVFS functionality. Highlights: - model PLLs and all PLL-derived clocks - model parent/child relationships of PLLs and clocks - convert to new clkdev layer - view clock frequency and refcount via /proc/davinci_clocks Special thanks to significant contributions and testing by David Brownell.

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.

2009-04-17Get rid of final remnants of include/asm-$(ARCH)Linus Torvalds
This renames include/asm-h8300/timer.h into arch/h8300/include/asm: it was left over just because that file had been created in the -mm tree before the whole h8300 header subdirectory had been moved, and then got merged in the old location afterwards. (See commits e0b0f9e4ead2468f84c26332ec42b118e76af572: "h8300: update timer handler - new files" and 758db3f2118703a1e36374dae5d58bed963e7e0d: "[h8300] move include/asm-h8300 to arch/h8300/include/asm" for details).

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.

2009-04-16x86: UV BAU distribution and payload MMRsCliff Wickman
This patch correctly sets BAU memory mapped registers to point to the sending activation descriptor table and target payload table. The "Broadcast Assist Unit" is used for TLB shootdown in UV. The memory mapped registers that point to sending and receiving memory structures contain node numbers. In one case the __pa() function did not provide the node id of memory on blade zero in configurations where that id is nonzero. In another case, it was assumed that memory was allocated on the local node. That assumption is not true in a configuration in which the node has no memory. Tested on the UV hardware simulator.
