| | | * | ia64: dma_alloc_coherent always use GFP_DMAFUJITA Tomonori2008-09-081-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes dma_alloc_coherent use GFP_DMA at all times. This is necessary for swiotlb, which requires the callers to set up the gfp flags properly. swiotlb_alloc_coherent tries to allocate pages with the gfp flags. If the allocated memory isn't fit for dev->coherent_dma_mask, swiotlb_alloc_coherent reserves some of the swiotlb memory area, which is precious resource. So the callers need to set up the gfp flags properly. This patch means that other IA64 IOMMUs' dma_alloc_coherent also use GFP_DMA. These IOMMUs (e.g. SBA IOMMU) don't need GFP_DMA since they can map a memory to any address. But IA64's GFP_DMA is large, generally drivers allocate small memory with dma_alloc_coherent only at startup. So I chose the simplest way to set up the gfp flags for swiotlb.

* | | | | [IA64] Put the space for cpu0 per-cpu area into .data sectionTony Luck2008-09-291-0/+3
|/ / / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Initial fix for making sure that we can access percpu variables in all C code (commit: 10617bbe84628eb18ab5f723d3ba35005adde143) inadvertantly allocated the memory in the "percpu" section of the vmlinux ELF executable. This confused kexec/dump. Signed-off-by: Tony Luck <tony.luck@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | bte.h expects a #define of L1_CACHE_MASK which is currently only in bte.c.

* | | | [IA64] fix compile failure with non modular buildsJames Bottomley2008-09-102-1/+27
| |_|/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Broke the non modular builds by moving an essential function into modules.c. Fix this by moving it out again and into asm/sections.h as an inline. To do this, the definitions of struct fdesc and struct got_val have been lifted out of modules.c and put in asm/elf.h where they belong.

* | | lib: Correct printk %pF to work on all architecturesJames Bottomley2008-09-091-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It was introduced by "vsprintf: add support for '%pS' and '%pF' pointer formats" in commit 0fe1ef24f7bd0020f29ffe287dfdb9ead33ca0b2. However, the current way its coded doesn't work on parisc64. For two reasons: 1) parisc isn't in the #ifdef and 2) parisc has a different format for function descriptors Make dereference_function_descriptor() more accommodating by allowing architecture overrides. I put the three overrides (for parisc64, ppc64 and ia64) in arch/kernel/module.c because that's where the kernel internal linker which knows how to deal with function descriptors sits.

* | | [IA64] Fix __{in,out}s{w,l} to handle unaligned dataJames Bottomley2008-08-251-4/+6
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | Some ia64 systems produce several repeats of kernel messages like this: kernel unaligned access to 0xe000000644220466, ip=0xa000000100516fa1 This was tracked to ide code using the __cmd[] field in "struct request" via the __outsw() function. __cmd[] is a char array, so is not guaranteed to be properly aligned when accessed as words.

* | kexec jump: rename KEXEC_CONTROL_CODE_SIZE to KEXEC_CONTROL_PAGE_SIZEHuang Ying2008-08-151-1/+1
|/ | | | | | | | | | | | | | | | | | Rename KEXEC_CONTROL_CODE_SIZE to KEXEC_CONTROL_PAGE_SIZE, because control page is used for not only code on some platform. For example in kexec jump, it is used for data and stack too.

* [IA64] Move include/asm-ia64 to arch/ia64/include/asmTony Luck2008-08-01185-0/+29363
After moving the the include files there were a few clean-ups: 1) Some files used #include <asm-ia64/xyz.h>, changed to <asm/xyz.h> 2) Some comments alerted maintainers to look at various header files to make matching updates if certain code were to be changed. Updated these comments to use the new include paths. 3) Some header files mentioned their own names in initial comments. Just deleted these self references.
