| * fbdev: move logo externs to header fileGeert Uytterhoeven2009-06-162-13/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now we have __initconst, we can finally move the external declarations for the various Linux logo structures to <linux/linux_logo.h>. James' ack dates back to the previous submission (way to long ago), when the logos were still __initdata, which caused failures on some platforms with some toolchain versions.

| * page allocator: do not check NUMA node ID when the caller knows the node is ↵Mel Gorman2009-06-161-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | valid Callers of alloc_pages_node() can optionally specify -1 as a node to mean "allocate from the current node". However, a number of the callers in fast paths know for a fact their node is valid. To avoid a comparison and branch, this patch adds alloc_pages_exact_node() that only checks the nid with VM_BUG_ON(). Callers that know their node is valid are then converted.

| * time: move PIT_TICK_RATE to linux/timex.hArnd Bergmann2009-06-161-7/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PIT_TICK_RATE is currently defined in four architectures, but in three different places. While linux/timex.h is not the perfect place for it, it is still a reasonable replacement for those drivers that traditionally use asm/timex.h to get CLOCK_TICK_RATE and expect it to be the PIT frequency. Note that for Alpha, the actual value changed from 1193182UL to 1193180UL. This is unlikely to make a difference, and probably can only improve accuracy. There was a discussion on the correct value of CLOCK_TICK_RATE a few years ago, after which every existing instance was getting changed to 1193182. According to the specification, it should be 1193181.818181...

| * | ps3: Replace direct file operations by callbackGeert Uytterhoeven2009-06-152-63/+82
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the FLASH database is updated by the kernel using file operations, meant for userspace only. While this works for us because copy_{from,to}_user() on powerpc can handle kernel pointers, this is unportable and a bad example. Replace the file operations by callbacks, registered by the ps3flash driver.

| * | powerpc: Add compiler memory barrier to mtmsr macroPaul Mackerras2009-06-152-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On 32-bit non-Book E, local_irq_restore() turns into just mtmsr(), which doesn't currently have a compiler memory barrier. This means that accesses to memory inside a local_irq_save/restore section, or a spin_lock_irqsave/spin_unlock_irqrestore section on UP, can be reordered by the compiler to occur outside that section. To fix this, this adds a compiler memory barrier to mtmsr for both 32-bit and 64-bit. Having a compiler memory barrier in mtmsr makes sense because it will almost always be changing something about the context in which memory accesses are done, so in general we don't want memory accesses getting moved from one side of an mtmsr to the other. With the barrier in mtmsr(), some of the explicit barriers in hw_irq.h are now redundant, so this removes them.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 28794d34 ("powerpc/kconfig: Kill PPC_MULTIPLATFORM"), added CONFIG_PPC_OF_BOOT_TRAMPOLINE to control the buliding of prom_init.o However the Makefile still unconditionally builds prom_init_check, the script that checks prom_init.o for symbol usage, and so in turn prom_init.o is still always being built. (it's not linked though) So surround all the prom_init_check logic with an ifeq block testing if CONFIG_PPC_OF_BOOT_TRAMPOLINE is set.

This disables the option for the single board configs, as it isn't used by anything for these boards.

| * | | | | powerpc: Add support for swiotlb on 32-bitBecky Bruce2009-06-098-2/+226
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch includes the basic infrastructure to use swiotlb bounce buffering on 32-bit powerpc. It is not yet enabled on any platforms. Probably the most interesting bit is the addition of addr_needs_map to dma_ops - we need this as a dma_op because the decision of whether or not an addr can be mapped by a device is device-specific.
