2012-07-04ARM: prima2: enable gpiolib unconditionallyArnd Bergmann1-1/+1
The pinctrl code needs GPIOLIB to be enabled, so make sure that it cannot be built otherwise. This fixes the prima2_defconfig. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Barry Song <21cnbao@gmail.com>
2012-07-02PINCTRL: SiRF: add GPIO and GPIO irq support in CSR SiRFprimaIIBarry Song3-1/+15
In SiRFprimaII, Each GPIO pin can be configured as input or output independently. If a GPIO is configured as input, it can also be enabled as an interrupt source (either edge or level triggered). These pins must be either MUXed as GPIO or other function pads.

2012-07-01ARM: 7438/1: fill possible PMD empty section gapsNicolas Pitre1-0/+74
On ARM with the 2-level page table format, a PMD entry is represented by two consecutive section entries covering 2MB of virtual space. However, static mappings always were allowed to use separate 1MB section entries. This means in practice that a static mapping may create half populated PMDs via create_mapping(). Since commit 0536bdf33f (ARM: move iotable mappings within the vmalloc region) those static mappings are located in the vmalloc area. We must ensure no such half populated PMDs are accessible once vmalloc() or ioremap() start looking at the vmalloc area for nearby free virtual address ranges, or various things leading to a kernel crash will happen.

2012-06-29powerpc: check_and_cede_processor() never cedesAnton Blanchard2-1/+6
Commit f948501b36c6 ("Make hard_irq_disable() actually hard-disable interrupts") caused check_and_cede_processor to stop working. ->irq_happened will never be zero right after a hard_irq_disable so the compiler removes the call to cede_processor completely. The bug was introduced back in the lazy interrupt handling rework of 3.4 but was hidden until recently because hard_irq_disable did nothing. This issue will eventually appear in 3.4 stable since the hard_irq_disable fix is marked stable, so mark this one for stable too.

2012-06-29powerpc/ftrace: Do not trace restore_interrupts()Steven Rostedt1-1/+1
As I was adding code that affects all archs, I started testing function tracer against PPC64 and found that it currently locks up with 3.4 kernel. I figured it was due to tracing a function that shouldn't be, so I went through the following process to bisect to find the culprit: cat /debug/tracing/available_filter_functions > t num=`wc -l t` sed -ne "1,${num}p" t > t1 let num=num+1 sed -ne "${num},$p" t > t2 cat t1 > /debug/tracing/set_ftrace_filter echo function /debug/tracing/current_tracer <failed? bisect t1, if not bisect t2> It finally came down to this function: restore_interrupts() I'm not sure why this locks up the system. It just seems to prevent scheduling from occurring. Interrupts seem to still work, as I can ping the box. But all user processes freeze. When restore_interrupts() is not traced, function tracing works fine.

2012-06-29ppc64: fix missing to check all bits of _TIF_USER_WORK_MASK in preemptTiejun Chen1-57/+40
In entry_64.S version of ret_from_except_lite, you'll notice that in the !preempt case, after we've checked MSR_PR we test for any TIF flag in _TIF_USER_WORK_MASK to decide whether to go to do_work or not. However, in the preempt case, we do a convoluted trick to test SIGPENDING only if PR was set and always test NEED_RESCHED ... but we forget to test any other bit of _TIF_USER_WORK_MASK !!! So that means that with preempt, we completely fail to test for things like single step, syscall tracing, etc... This should be fixed as the following path: - Test PR. If not set, go to resume_kernel, else continue. - If go resume_kernel, to do that original do_work. - If else, then always test for _TIF_USER_WORK_MASK to decide to do that original user_work, else restore directly.

2012-06-25ARM: dma-mapping: fix buffer chunk allocation orderMarek Szyprowski1-1/+1
IOMMU-aware dma_alloc_attrs() implementation allocates buffers in power-of-two chunks to improve performance and take advantage of large page mappings provided by some IOMMU hardware. However current code, due to a subtle bug, allocated those chunks in the smallest-to-largest order, what completely killed all the advantages of using larger than page chunks. If a 4KiB chunk has been mapped as a first chunk, the consecutive chunks are not aligned correctly to the power-of-two which match their size and IOMMU drivers were not able to use internal mappings of size other than the 4KiB (largest common denominator of alignment and chunk size). This patch fixes this issue by changing to the correct largest-to-smallest chunk size allocation sequence. Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com>

2012-06-23ARM: Orion: Fix Virtual/Physical mixup with watchdogAndrew Lunn5-2/+5
The orion watchdog is expecting to be passed the physcial address of the hardware, and will ioremap() it to give a virtual address it will use as the base address for the hardware. However, when creating the platform resource record, a virtual address was being used. Add the necassary #define's so we can pass the physical address as expected. Tested on Kirkwood and Orion5x.

2012-06-23ARM: Kirkwood: clk_register_gate_fn: add fn assignmentMarc Kleine-Budde1-0/+1
In commit: 98d9986 ARM: Kirkwood: Replace clock gating the kirkwood clock gating has been reworked. A custom variant of clock gating, that calls a custom function before gating the clock off, has been introduced. However in clk_register_gate_fn() this custom function "fn" is never assigned. This patch adds the missing fn assignment.

2012-06-23ARM: Orion5x - Restore parts of io.h, with reworkAndrew Lunn2-0/+23
Commit 4d5fc58dbe34b78157c05b319669bb3e064ba8bd (ARM: remove bunch of now unused mach/io.h files) removed the orion5x io.h. Unfortunately, this is still needed for the definition of IO_SPACE_LIMIT which overrides the default 64K. All Orion based systems have 1Mbyte of IO space per PCI[e] bus, and try to request_resource() this size. Orion5x has two such PCI buses. It is likely that the original, removed version, was broken. This version might be less broken. However, it has not been tested on hardware with a PCI card, let alone hardware with a PCI card with IO capabilities.

2012-06-22ARM: 7428/1: Prevent KALLSYM size mismatch on ARM.David Brown1-0/+2
ARM builds seem to be plagued by an occasional build error: Inconsistent kallsyms data This is a bug - please report about it Try "make KALLSYMS_EXTRA_PASS=1" as a workaround The problem has to do with alignment of some sections by the linker. The kallsyms data is built in two passes by first linking the kernel without it, and then linking the kernel again with the symbols included. Normally, this just shifts the symbols, without changing their order, and the compression used by the kallsyms gives the same result. On non SMP, the per CPU data is empty. Depending on the where the alignment ends up, it can come out as either: +-------------------+ | last text segment | +-------------------+ /* padding */ +-------------------+ <- L1_CACHE_BYTES alignemnt | per cpu (empty) | +-------------------+ __per_cpu_end: /* padding */ __data_loc: +-------------------+ <- THREAD_SIZE alignment | data | +-------------------+ or +-------------------+ | last text segment | +-------------------+ /* padding */ +-------------------+ <- L1_CACHE_BYTES alignemnt | per cpu (empty) | +-------------------+ __per_cpu_end: /* no padding */ __data_loc: +-------------------+ <- THREAD_SIZE alignment | data | +-------------------+ if the alignment satisfies both. Because symbols that have the same address are sorted by 'nm -n', the second case will be in a different order than the first case. This changes the compression, changing the size of the kallsym data, causing the build failure. The KALLSYMS_EXTRA_PASS=1 workaround usually works, but it is still possible to have the alignment change between the second and third pass. It's probably even possible for it to never reach a fixedpoint. The problem only occurs on non-SMP, when the per-cpu data is empty, and when the data segment has alignment (and immediately follows the text segments). Fix this by only including the per_cpu section on SMP, when it is not empty. Signed-off-by: David Brown <davidb@codeaurora.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-06-21ARM: OMAP4: hwmod data: Force HDMI in no-idle while enabledRicardo Neri1-0/+5
As per the OMAP4 documentation, audio over HDMI must be transmitted in no-idle mode. This patch adds the HWMOD_SWSUP_SIDLE so that omap_hwmod uses no-idle/force-idle settings instead of smart-idle mode. This is required as the DSS interface clock is used as functional clock for the HDMI wrapper audio FIFO. If no-idle mode is not used, audio could be choppy, have bad quality or not be audible at all.

2012-06-21ARM: OMAP4: clock data: add clockdomains for clocks used as main clocksPaul Walmsley1-0/+5
Until the OMAP4 code is converted to disable the use of the clock framework-based clockdomain enable/disable sequence, any clock used as a hwmod main_clk must have a clockdomain associated with it. This patch populates some clock structure clockdomain names to resolve the following warnings during kernel init: omap_hwmod: dpll_mpu_m2_ck: missing clockdomain for dpll_mpu_m2_ck. omap_hwmod: trace_clk_div_ck: missing clockdomain for trace_clk_div_ck. omap_hwmod: l3_div_ck: missing clockdomain for l3_div_ck. omap_hwmod: ddrphy_ck: missing clockdomain for ddrphy_ck.
