alpha: silence 'const' warning in sys_marvel.c

2012-05-02T19:54:06Z

warning: passing argument 1 of 'pci_find_capability' discards 'const' qualifier from pointer target type Signed-off-by: Matt Turner

alpha: properly define get/set_rtc_time on Marvel/SMP

2012-05-02T19:54:05Z

The marvel_get_rtc_time and marvel_set_rtc_time are static, but they're available through Marvel's machine vector. Reported-by: Raúl Porcel Signed-off-by: Matt Turner

alpha: VGA_HOSE depends on VGA_CONSOLE

2012-05-02T19:54:05Z

arch/alpha/kernel/console.c:locate_and_init_vga uses vga_con, causing build failures if VGA_CONSOLE was not set and MARVEL, TITAN, DP264, or GENERIC alpha system types were set. Reported-by: Raúl Porcel Signed-off-by: Matt Turner

alpha: fix build failures from system.h dismemberment

2012-04-13T17:15:16Z

commit ec2212088c42ff7d1362629ec26dda4f3e8bdad3 "Disintegrate asm/system.h for Alpha" combined with commit b4816afa3986704d1404fc48e931da5135820472 "Move the asm-generic/system.h xchg() implementation to asm-generic/cmpxchg.h" introduced the concept of asm/cmpxchg.h but the alpha arch never got one. Fork the cmpxchg content out of the asm/atomic.h file to create one. Some minor whitespace fixups were done on the block of code that created the new file.

Merge branch 'akpm' (Andrew's patch-bomb)

2012-04-05T22:30:34Z

Merge batch of fixes from Andrew Morton: "The simple_open() cleanup was held back while I wanted for laggards to merge things. I still need to send a few checkpoint/restore patches. I've been wobbly about merging them because I'm wobbly about the overall prospects for success of the project. But after speaking with Pavel at the LSF conference, it sounds like they're further toward completion than I feared - apparently davem is at the "has stopped complaining" stage regarding the net changes. So I need to go back and re-review those patchs and their (lengthy) discussion." * emailed from Andrew Morton : (16 patches) memcg swap: use mem_cgroup_uncharge_swap fix backlight: add driver for DA9052/53 PMIC v1 C6X: use set_current_blocked() and block_sigmask() MAINTAINERS: add entry for sparse checker MAINTAINERS: fix REMOTEPROC F: typo alpha: use set_current_blocked() and block_sigmask() simple_open: automatically convert to simple_open() scripts/coccinelle/api/simple_open.cocci: semantic patch for simple_open() libfs: add simple_open() hugetlbfs: remove unregister_filesystem() when initializing module drivers/rtc/rtc-88pm860x.c: fix rtc irq enable callback fs/xattr.c:setxattr(): improve handling of allocation failures fs/xattr.c:listxattr(): fall back to vmalloc() if kmalloc() failed fs/xattr.c: suppress page allocation failure warnings from sys_listxattr() sysrq: use SEND_SIG_FORCED instead of force_sig() proc: fix mount -t proc -o AAA

alpha: use set_current_blocked() and block_sigmask()

2012-04-05T22:25:51Z

As described in e6fa16ab9c1e ("signal: sigprocmask() should do retarget_shared_pending()") the modification of current->blocked is incorrect as we need to check for shared signals we're about to block. Also, use the new helper function introduced in commit 5e6292c0f28f ("signal: add block_sigmask() for adding sigmask to current->blocked") which centralises the code for updating current->blocked after successfully delivering a signal and reduces the amount of duplicate code across architectures. In the past some architectures got this code wrong, so using this helper function should stop that from happening again.

Merge branch 'for-linus' of git://git.linaro.org/people/mszyprowski/linux-dma-mapping

2012-04-05T00:13:43Z

Pull DMA mapping branch from Marek Szyprowski: "Short summary for the whole series: A few limitations have been identified in the current dma-mapping design and its implementations for various architectures. There exist more than one function for allocating and freeing the buffers: currently these 3 are used dma_{alloc, free}_coherent, dma_{alloc,free}_writecombine, dma_{alloc,free}_noncoherent. For most of the systems these calls are almost equivalent and can be interchanged. For others, especially the truly non-coherent ones (like ARM), the difference can be easily noticed in overall driver performance. Sadly not all architectures provide implementations for all of them, so the drivers might need to be adapted and cannot be easily shared between different architectures. The provided patches unify all these functions and hide the differences under the already existing dma attributes concept. The thread with more references is available here: http://www.spinics.net/lists/linux-sh/msg09777.html These patches are also a prerequisite for unifying DMA-mapping implementation on ARM architecture with the common one provided by dma_map_ops structure and extending it with IOMMU support. More information is available in the following thread: http://thread.gmane.org/gmane.linux.kernel.cross-arch/12819 More works on dma-mapping framework are planned, especially in the area of buffer sharing and managing the shared mappings (together with the recently introduced dma_buf interface: commit d15bd7ee445d "dma-buf: Introduce dma buffer sharing mechanism"). The patches in the current set introduce a new alloc/free methods (with support for memory attributes) in dma_map_ops structure, which will later replace dma_alloc_coherent and dma_alloc_writecombine functions." People finally started piping up with support for merging this, so I'm merging it as the last of the pending stuff from the merge window. Looks like pohmelfs is going to wait for 3.5 and more external support for merging. * 'for-linus' of git://git.linaro.org/people/mszyprowski/linux-dma-mapping: common: DMA-mapping: add NON-CONSISTENT attribute common: DMA-mapping: add WRITE_COMBINE attribute common: dma-mapping: introduce mmap method common: dma-mapping: remove old alloc_coherent and free_coherent methods Hexagon: adapt for dma_map_ops changes Unicore32: adapt for dma_map_ops changes Microblaze: adapt for dma_map_ops changes SH: adapt for dma_map_ops changes Alpha: adapt for dma_map_ops changes SPARC: adapt for dma_map_ops changes PowerPC: adapt for dma_map_ops changes MIPS: adapt for dma_map_ops changes X86 & IA64: adapt for dma_map_ops changes common: dma-mapping: introduce generic alloc() and free() methods

Pull cpumask cleanups from Rusty Russell: "(Somehow forgot to send this out; it's been sitting in linux-next, and if you don't want it, it can sit there another cycle)" I'm a sucker for things that actually delete lines of code. Fix up trivial conflict in arch/arm/kernel/kprobes.c, where Rusty fixed a user of &cpu_online_map to be cpu_online_mask, but that code got deleted by commit b21d55e98ac2 ("ARM: 7332/1: extract out code patch function from kprobes"). * tag 'for-linus' of git://github.com/rustyrussell/linux: cpumask: remove old cpu_*_map. documentation: remove references to cpu_*_map. drivers/cpufreq/db8500-cpufreq: remove references to cpu_*_map. remove references to cpu_*_map in arch/
