2010-09-14ARM: SAMSUNG: Fix on s5p_gpio_[get,set]_drvstrKukjin Kim
This patch fixes bug on gpio drive strength helper function. The offset should be like follwoing. - off = chip->chip.base - pin; + off = pin - chip->chip.base; In the s5p_gpio_get_drvstr(), the second line is unnecessary, because overwrite drvstr. drvstr = __raw_readl(reg); - drvstr = 0xffff & (0x3 << shift); And need 2bit masking before return the drvstr value. drvstr = drvstr >> shift; + drvstr &= 0x3; In the s5p_gpio_set_drvstr(), need relevant bit clear. tmp = __raw_readl(reg); + tmp &= ~(0x3 << shift); tmp |= drvstr << shift; Reported-by: Jaecheol Lee <jc.lee@samsung.com> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
2010-09-14ARM: SAMSUNG: Fix on drive strength valueKukjin Kim
This patch fixes on defined drive strength value for GPIO.

2010-09-08ARM: Ensure PTE modifications via dma_alloc_coherent are visibleRussell King
Dave Hylands reports: | We've observed a problem with dma_alloc_writecombine when the system | is under heavy load (heavy bus traffic). We've managed to reduce the | problem to the following snippet, which is run from a kthread in a | continuous loop: | | void *virtAddr; | dma_addr_t physAddr; | unsigned int numBytes = 256; | | for (;;) { | virtAddr = dma_alloc_writecombine(NULL, | numBytes, &physAddr, GFP_KERNEL); | if (virtAddr == NULL) { | printk(KERN_ERR "Running out of memory\n"); | break; | } | | /* access DMA memory allocated */ | tmp = virtAddr; | *tmp = 0x77; | | /* free DMA memory */ | dma_free_writecombine(NULL, | numBytes, virtAddr, physAddr); | | ...sleep here... | } | | By itself, the code will run forever with no issues. However, as we | increase our bus traffic (typically using DMA) then the *tmp = 0x77 | line will eventually cause a page fault. If we add a small delay (a | few microseconds) before the *tmp = 0x77, then we don't see a page | fault, even under heavy load. A dsb() is required after modifying the PTE entries to ensure that they will always be visible. Add this dsb().

2010-09-08ARM: 6359/1: ep93xx: move clock initialization earlierMika Westerberg
Commit 7cfe24947 ("ARM: AMBA: Add pclk support to AMBA bus infrastructure") changed AMBA bus to handle the PCLK automatically. However, in EP93xx clock initialization is arch_initcall which is done later than AMBA device identification. This causes amba_get_enable_pclk() to fail resulting device where UARTs are not functional. So change ep93xx_clock_init() to be postcore_initcall.

2010-09-02ARM: 6352/1: perf: fix event validationWill Deacon
The validate_event function in the ARM perf events backend has the following problems: 1.) Events that are disabled count towards the cost. 2.) Events associated with other PMUs [for example, software events or breakpoints] do not count towards the cost, but do fail validation, causing the group to fail. This patch changes validate_event so that it ignores events in the PERF_EVENT_STATE_OFF state or that are scheduled for other PMUs.

2010-09-01ARM: 6343/1: wire up fanotify and prlimit64 syscalls on ARMMikael Pettersson
The 2.6.36-rc kernel added three new system calls: fanotify_init, fanotify_mark, and prlimit64. This patch wires them up on ARM. The only non-trivial issue here is the u64 argument to sys_fanotify_mark(), but it is the 3rd argument and thus passed in r2/r3 in both kernel and user space, so it causes no problems. Tested with a 2.6.36-rc2 EABI kernel on an ixp4xx machine.
