2011-05-16arm: orion: Use generic irq chipThomas Gleixner3-117/+45
The core interrupt chip is a straight forward conversion. The gpio chip is implemented with two instances of the irq_chip_type which can be switched with the irq_set_type function. That allows us to use the generic callbacks and avoids the conditionals in them. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Nicolas Pitre <nico@fluxnic.net>

2011-05-11ARM: GIC: Convert GIC library to use the IO relaxed operationsSantosh Shilimkar1-24/+30
The GIC register accesses today make use of readl()/writel() which prove to be very expensive when used along with mandatory barriers. This mandatory barriers also introduces an un-necessary and expensive l2x0_sync() operation. On Cortex-A9 MP cores, GIC IO accesses from CPU are direct and doesn't go through L2X0 write buffer. A DSB before writel_relaxed() in gic_raise_softirq() is added to be compliant with the Barrier Litmus document - the mailbox scenario.

2011-05-11ARM: gic: use handle_fasteoi_irq for SPIsWill Deacon1-16/+16
Currently, the gic uses handle_level_irq for handling SPIs (Shared Peripheral Interrupts), requiring active interrupts to be masked at the distributor level during IRQ handling. On a virtualised system, only the CPU interfaces are virtualised in hardware. Accesses to the distributor must be trapped by the hypervisor, adding latency to the critical interrupt path in Linux. This patch modifies the GIC code to use handle_fasteoi_irq for handling interrupts, which only requires us to signal EOI to the CPU interface when handling is complete. Cascaded IRQ handling is also updated to use the chained IRQ enter/exit functions to honour the flow control of the parent chip. Note that commit 846afbd1 ("GIC: Dont disable INT in ack callback") broke cascading interrupts by forgetting to add IRQ masking. This is no longer an issue because the unmask call is now unnecessary. Tested on Versatile Express and Realview EB (1176 w/ cascaded GICs).

Commit a626ca6a6564 ("vm: fix vm_pgoff wrap in stack expansion") fixed the case of an expanding mapping causing vm_pgoff wrapping when you had downward stack expansion. But there was another case where IA64 and PA-RISC expand mappings: upward expansion. This fixes that case too.

2011-05-10Don't lock guardpage if the stack is growing upMikulas Patocka3-15/+37
Linux kernel excludes guard page when performing mlock on a VMA with down-growing stack. However, some architectures have up-growing stack and locking the guard page should be excluded in this case too. This patch fixes lvm2 on PA-RISC (and possibly other architectures with up-growing stack). lvm2 calculates number of used pages when locking and when unlocking and reports an internal error if the numbers mismatch. [ Patch changed fairly extensively to also fix /proc/<pid>/maps for the grows-up case, and to move things around a bit to clean it all up and share the infrstructure with the /proc bits.

Despite the fixes in 548f245ba6a31 (drm/i915: fix per-pipe reads after "cleanup"), we missed one neighbouring read that was mistakenly replaced with the reg value in 9db4a9c (drm/i915: cleanup per-pipe reg usage).
