2012-12-13microblaze: Fix intc_enable_or_unmask functionMichal Simek
Intc_enable_or_unmask() is called at the last stage of handle_level_irq(). This function enables the irq first (Write INTC.SIE) and clear ISR next (Write INTC.IAR). This would create problems that processor will get into a new interrupt as soon as SIE is written because the previous level interrupt has been captured by INTC. If the description bring some puzzles, here is the details of how interrupt is handled for MicroBlaze after Interrupt signal is detected: 1. disable INTC (INTC.CIE = 1) 2. Acknowledge INTC (INTC.IAR = 1) 3. gets into interrupt source's handler, for example, timer's handler 4. Timer is interrupt handler acknowledge Timer Interrupt Status (Timer.TCSR0[23] = 1), and return 5. Enable INTC (INTC.SIE = 1) 6. Acknowledge INTC (INTC.IAR = 1) INTC continue to capture source inputs even if INTC is disabled (INTC.IER == 1). So between the gap of step 2 and step 3, the level interrupt from source makes INTC captures a new interrupt and thus the INTC.ISR = 1 during step 3, 4, and 5. When INTC is enabled in step 5, INTC's interrupt output will go high immediately. In summary, the driver should issue step 6 before step 5. Signed-off-by: Michal Simek <michal.simek@xilinx.com>

2012-12-13microblaze: uaccess.h: Fix timerfd syscallMichal Simek
__pu_val must be volatile to ensure that the value is not lost. It was causing the problem with timerfd syscall where using inline asm at the end of function call doesn't save u64 bit value to the stack. In comparison both cases you can find out this fragment where you can see the first part which is saved u64 value to stack and then using it in __put_user_asm_8 macro. Origin broken implementation misses the first two swi instructions. swi r22, r1, 28 /* missing without volatile */ swi r23, r1, 32 ... addik r4, r1, 28 lwi r3, r4, 0 swi r3, r25, 0 lwi r3, r4, 4 swi r3, r25, 4 addk r3, r0, r0 NOTE: Moving __put_val initialization after declaration has not impact on this bug. It is just coding style issue. Signed-off-by: Michal Simek <monstr@monstr.eu>

2012-12-13OMAPDSS: fix TV-out issue with DSI PLLTomi Valkeinen
Commit 0e8276ef75f5c7811b038d1d23b2b42c16efc5ac (OMAPDSS: DPI: always use DSI PLL if available) made dpi.c use DSI PLL for its clock. This works fine, for DPI, but has a nasty side effect on OMAP3: On OMAP3 the same clock is used for DISPC fclk and LCD output. Thus, after the above patch, DSI PLL is used for DISPC and LCD output. If TV-out is used, the TV-out needs DISPC. And if DPI is turned off, the DSI PLL is also turned off, disabling DISPC. For this to work, we'd need proper DSS internal clock handling, with refcounts, which is a non-trivial project. This patch fixes the issue for now by disabling the use of DSI PLL for DPI on OMAP3.

2012-12-13mtd: block2mtd: throttle writes by calling balance_dirty_pages_ratelimited.NeilBrown
If you create a block2mtd device that is larger than main memory, and write to all of it, then lots of pages will be dirtied but they will never be flushed out as nothing calls any variant of balance_dirty_pages.

2012-12-13mtd: nand: gpmi: reset BCH earlier, too, to avoid NAND startup problemsWolfram Sang
It could happen (1 out of 100 times) that NAND did not start up correctly after warm rebooting, so the kernel could not find the UBI or DMA timed out due to a stalled BCH. When resetting BCH together with GPMI, the issue could not be observed anymore (after 10000+ reboots). We probably need the consistent state already before sending any command to NAND, even when no ECC is needed. I chose to keep the extra reset for BCH when changing the flash layout to be on the safe side.

2012-12-13usb: gadget: dummy: fix enumeration with g_multiSebastian Andrzej Siewior
If we do have endpoints named like "ep-a" then bEndpointAddress is counted internally by the gadget framework. If we do have endpoints named like "ep-1" then bEndpointAddress is assigned from the digit after "ep-". If we do have both, then it is likely that after we used up the "generic" endpoints we will use the digits and thus assign one bEndpointAddress to multiple endpoints. This theory can be proofed by using the completely enabled g_multi. Without this patch, the mass storage won't enumerate and times out because it shares endpoints with RNDIS. This patch also adds fills up the endpoints list so we have in total endpoints 1 to 15 in + out available while some of them are restricted to certain types like BULK or ISO. Without this change the nokia gadget won't load because the system does not provide enough (BULK) endpoints but it did before ep-a - ep-f were removed.

2012-12-13Blackfin: Annotate strncpy_from_user src parameter with __userLars-Peter Clausen
The src parameter of strncpy_from_user is supposed to take a string from userspace, so it should be annotated with __user. Doing so fixes the following and similar warnings from sparse: kernel/sys.c:491:51: warning: incorrect type in argument 2 (different address spaces) kernel/sys.c:491:51: expected char const *src kernel/sys.c:491:51: got void [noderef] <asn:1>*arg kernel/sys.c:2061:54: warning: incorrect type in argument 2 (different address spaces) kernel/sys.c:2061:54: expected char const *src kernel/sys.c:2061:54: got char [noderef] <asn:1>*<noident> Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Bob Liu <lliubbo@gmail.com>

Optimize RAID6 recovery functions to take advantage of the 256-bit YMM integer instructions introduced in AVX2. The patch was tested and benchmarked before submission. However hardware is not yet released so benchmark numbers cannot be reported. Acked-by: "H.

2012-12-13md: Update checkpoint of resync/recovery based on time.majianpeng
md will current only only checkpoint recovery or resync ever 1/16th of the device size. As devices get larger this can become a long time an so a lot of work that might need to be duplicated after a shutdown. So add a time-based checkpoint. Every 5 minutes limits the amount of duplicated effort to at most 5 minutes, and has almost zero impact on performance.
