2013-05-31drm, agpgart: Use pgprot_writecombine for AGP maps and make the MTRR optionalAndy Lutomirski
I'm not sure I understand the intent of the previous behavior. mmap on /dev/agpgart and DRM_AGP maps had no cache flags set, so they would be fully cacheable. But the DRM code (most of the time) would add a write-combining MTRR that would change the effective memory type to WC. The new behavior just requests WC explicitly for all AGP maps. If there is any code out there that expects cacheable access to the AGP aperture (because the drm driver doesn't request an MTRR or because it's using /dev/agpgart directly), then it will now end up with a UC or WC mapping, depending on the architecture and PAT availability. But cacheable access to the aperture seems like it's asking for trouble, because, AIUI, the aperture is an alias of RAM.

2013-05-31drm: Update drm_addmap and drm_mmap to use PAT WC instead of MTRRsAndy Lutomirski
Previously, DRM_FRAME_BUFFER mappings, as well as DRM_REGISTERS mappings with DRM_WRITE_COMBINING set, resulted in an unconditional MTRR being added but the actual mappings being created as UC-. Now these mappings have the MTRR added only if needed, but they will be mapped with pgprot_writecombine. The non-WC DRM_REGISTERS case now uses pgprot_noncached instead of hardcoding the bit twiddling. The DRM_AGP case is unchanged for now.

2013-05-31drm (ast, cirrus, mgag200, nouveau, savage, vmwgfx): Remove drm_mtrr_{add, del}Andy Lutomirski
This replaces drm_mtrr_{add,del} with arch_phys_wc_{add,del}. The interface is simplified (because the base and size parameters to drm_mtrr_del never did anything), and it no longer adds MTRRs on systems that don't need them.

2013-05-31Add arch_phys_wc_{add, del} to manipulate WC MTRRs if neededAndy Lutomirski
Several drivers currently use mtrr_add through various #ifdef guards and/or drm wrappers. The vast majority of them want to add WC MTRRs on x86 systems and don't actually need the MTRR if PAT (i.e. ioremap_wc, etc) are working. arch_phys_wc_add and arch_phys_wc_del are new functions, available on all architectures and configurations, that add WC MTRRs on x86 if needed (and handle errors) and do nothing at all otherwise. They're also easier to use than mtrr_add and mtrr_del, so the call sites can be simplified. As an added benefit, this will avoid wasting MTRRs and possibly warning pointlessly on PAT-supporting systems.

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus Jonathan writes: First round of IIO fixes for the 3.10 cycle. The usual mixed bag of little fixes. 1) A fix for mxs-lradc having missed out on some global abi changes that and hence being unable to start up buffered output. 2) Clean up error handling in tsl2x7x 3) A build fix for some of the dac drivers when they have spi master support built in, but i2c support build as a module. 4) Add a missing disable after a oneshot capture to the st sensor core. 5) Exynos adc driver took a novel an incorrect route to get at its private data store.
2013-05-22iio: exynos_adc: fix wrong structure extration in suspend and resumeNaveen Krishna Chatradhi
The exynos_adc device structure was wrongly extracted from the dev* correcting the same. Using the regular conversion of struct device* -> struct platform_device* -> struct exynos_adc* seems wrong. Instead we should be doing struct device* -> struct iio_dev* -> struct exynos_adc* Signed-off-by: Naveen Krishna Chatradhi <ch.naveen@samsung.com> Reviewed-by: Doug Anderson <dianders@chromium.org> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

2013-05-22iio: dac: Fix build error when CONFIG_SPI_MASTER=y && CONFIG_I2C=mAxel Lin
This patch fixes below build error when CONFIG_SPI_MASTER=y && CONFIG_I2C=m: drivers/built-in.o: In function `ad5064_i2c_write': drivers/iio/dac/ad5064.c:608: undefined reference to `i2c_master_send' drivers/built-in.o: In function `ad5064_i2c_register_driver': drivers/iio/dac/ad5064.c:646: undefined reference to `i2c_register_driver' drivers/built-in.o: In function `ad5064_i2c_unregister_driver': drivers/iio/dac/ad5064.c:651: undefined reference to `i2c_del_driver' make: *** [vmlinux] Error 1 When CONFIG_I2C=m, meaning we can't build the drivers in with I2C support. Thus don't allow the drivers to be compiled as built-in when CONFIG_I2C=m. The real fix though is to break the driver apart into a SPI part, an I2C part and a common part. But that's something for 3.11 while this is something for 3.10/stable.

2013-05-22mm: Fix virt_to_page() warningRalf Baechle
virt_to_page() is typically implemented as a macro containing a cast so that it will accept both pointers and unsigned long without causing a warning. But MIPS virt_to_page() uses virt_to_phys which is a function so passing an unsigned long will cause a warning: CC mm/page_alloc.o mm/page_alloc.c: In function ‘free_reserved_area’: mm/page_alloc.c:5161:3: warning: passing argument 1 of ‘virt_to_phys’ makes pointer from integer without a cast [enabled by default] arch/mips/include/asm/io.h:119:100: note: expected ‘const volatile void *’ but argument is of type ‘long unsigned int’ All others users of virt_to_page() in mm/ are passing a void *.

2013-05-22MIPS: N64: Wire getdents64(2)Aron Xu
As a relatively new ABI, N64 only had getdents syscall while other modern architectures have getdents64. This was noticed when Python 3.3 shifted to the latter one for aarch64. [ralf@linux-mips.org: The history of getdents64 is a little complicated. Commit 1a1d77dd589de5a567fa95e36aa6999c704ceca4 [Merge with 2.4.0-test7.] added N64 getdents(2) to arch/mips64/kernel/scall_64.S as syscall 5213, then dropped again in 578720675c44e54e8aa7c68f6dce59ed37ce3d3b [Overhaul of the 64-bit syscall interface.
