The current code uses multiple if statements for demultiplexing the different interrupt sources. Additionally, the MISC interrupt controller has 32 interrupt sources and the current code does not handles all of them. Get rid of the if statements and process all interrupt sources in a loop to fix these issues.

GPIO function selection is not working on the AR934x SoCs because the offset of the function selection register is different on those. Add a helper routine which returns the correct register address based on the SoC type, and use that in the 'ath79_gpio_function_*' routines.

Doing calibrate delay on a hardware thread will be inaccurate since it depends on the load on other threads in the core. It will also slow down the boot process when done for 128 hardware threads. Switch to a pre-computed loops per jiffy based on the core frequency. The value is computed based on the core frequency and roughly matches the value calculated by calibrate_delay().

The XLR/XLS/XLP PIC has a 8 countdown timers which run at the PIC frequencey. One of these can be used as a clocksource to provide timestamps that is common across cores. This can be used in place of the count/compare clocksource which is per-CPU. On XLR/XLS PIC registers are 32-bit, so we just use the lower 32-bits of the PIC counter. On XLP, the whole 64-bit can be used. Provide common macros and functions for PIC timer registers on XLR/XLS and XLP, and use them to register a PIC clocksource.

Rename function xlp_enable_pci_bswap() to xlp_config_pci_bswap(), which is a better description for its functionality. When compiled in big-endian mode, xlp_config_pci_bswap() will configure the PCIe links to byteswap. In little-endian mode, no swap configuration is needed for the PCIe controller, and the function is empty.

Provide functions ack_c0_eirr(), set_c0_eimr(), clear_c0_eimr() and read_c0_eirr_and_eimr() that do the EIMR and EIRR operations and update the interrupt handling code to use these functions. Also, use the EIMR register functions to mask interrupts in the irq code. The 64-bit interrupt request and mask registers (EIRR and EIMR) are accessed when the interrupts are off, and the common operations are to set or clear a bit in these registers. Using the 64-bit c0 access functions for these operations is not optimal in 32-bit, because it will disable/restore interrupts and split/join the 64-bit value during each register access.

Pull ARM fixes from Russell King: "I was going to hold these off until v3.8 was out, and send them with a stable tag, but as everyone else is pushing much bigger fixes which Linus is accepting, let's save people from the hastle of having to patch v3.8 back into working or use a stable kernel. Looking at the diffstat, this really is high value for its size; this is miniscule compared to how the -rc6 to tip diffstat currently looks. So, four patches in this set: - Punit Agrawal reports that the kernel no longer boots on MPCore due to a new assumption made in the GIC code which isn't true of earlier GIC designs. This is the biggest change in this set. - Punit's boot log also revealed a bunch of WARN_ON() dumps caused by the DT-ification of the GIC support without fixing up non-DT Realview - which now sees a greater number of interrupts than it did before. - A fix for the DMA coherent code from Marek which uses the wrong check for atomic allocations; this can result in spinlock lockups or other nasty effects. - A fix from Will, which will affect all Android based platforms if not applied (which use the 2G:2G VM split) - this causes particularly 'make' to misbehave unless this bug is fixed." * 'fixes' of git://git.linaro.org/people/rmk/linux-arm: ARM: 7641/1: memory: fix broken mmap by ensuring TASK_UNMAPPED_BASE is aligned ARM: DMA mapping: fix bad atomic test ARM: realview: ensure that we have sufficient IRQs available ARM: GIC: fix GIC cpumask initialization

Tsirkin. 7) Don't leak socket reference counts and ubufs in vhost-net driver, from Jason Wang. 8) vmxnet3 driver gets it's initial carrier state wrong, fix from Neil Horman. 9) Protect against USB networking devices which spam the host with 0 length frames, from Bjørn Mork. 10) Prevent neighbour overflows in ipv6 for locally destined routes, from Marcelo Ricardo. This is the best short-term fix for this, a longer term fix has been implemented in net-next. 11) L2TP uses ipv4 datagram routines in it's ipv6 code, whoops. This mistake is largely because the ipv6 functions don't even have some kind of prefix in their names to suggest they are ipv6 specific. From Tom Parkin. 12) Check SYN packet drops properly in tcp_rcv_fastopen_synack(), from Yuchung Cheng. 13) Fix races and TX skb freeing bugs in via-rhine's NAPI support, from Francois Romieu and your's truly. 14) Fix infinite loops and divides by zero in TCP congestion window handling, from Eric Dumazet, Neal Cardwell, and Ilpo Järvinen. 15) AF_PACKET tx ring handling can leak kernel memory to userspace, fix from Phil Sutter. 16) Fix error handling in ipv6 GRE tunnel transmit, from Tommi Rantala. 17) Protect XEN netback driver against hostile frontend putting garbage into the rings, don't leak pages in TX GOP checking, and add proper resource releasing in error path of xen_netbk_get_requests(). From Ian Campbell. 18) SCTP authentication keys should be cleared out and released with kzfree(), from Daniel Borkmann. 19) L2TP is a bit too clever trying to maintain skb->truesize, and ends up corrupting socket memory accounting to the point where packet sending is halted indefinitely. Just remove the adjustments entirely, they aren't really needed. From Eric Dumazet. 20) ATM Iphase driver uses a data type with the same name as the S390 headers, rename to fix the build.
