2013-04-16KVM: ARM: Fix kvm_vm_ioctl_irq_lineAlexander Graf
Commit aa2fbe6d broke the ARM KVM target by introducing a new parameter to irq handling functions.

2013-03-18ARM: fix CONFIG_VIRT_TO_BUS handlingArnd Bergmann
887cbce0 "arch Kconfig: centralise CONFIG_ARCH_NO_VIRT_TO_BUS" and 4febd95a8 "Select VIRT_TO_BUS directly where needed" from Stephen Rothwell changed globally how CONFIG_VIRT_TO_BUS is selected, while my own a5d533ee0 "ARM: disable virt_to_bus/ virt_to_bus almost everywhere" was merged at the same time and changed which platforms select it on ARM. The result of this conflict was that we again see CONFIG_VIRT_TO_BUS on all ARM systems. This patch fixes up the problem and removes CONFIG_ARCH_NO_VIRT_TO_BUS again on ARM.

2013-03-15ARM: 7674/1: smp: Avoid dummy clockevent being preferred over real hardware ↵Santosh Shilimkar
clock-event With recent arm broadcast time clean-up from Mark Rutland, the dummy broadcast device is always registered with timer subsystem. And since the rating of the dummy clock event is very high, it may be preferred over a real clock event. This is a change in behavior from past and not an intended one. So reduce the rating of the dummy clock-event so that real clock-event device is selected when available.

2013-03-15ARM: i.MX35: enable MAX clockSascha Hauer
The i.MX35 has two bits per clock gate which are decoded as follows: 0b00 -> clock off 0b01 -> clock is on in run mode, off in wait/doze 0b10 -> clock is on in run/wait mode, off in doze 0b11 -> clock is always on The reset value for the MAX clock is 0b10. The MAX clock is needed by the SoC, yet unused in the Kernel, so the common clock framework will disable it during late init time. It will only disable clocks though which it detects as being turned on. This detection is made depending on the lower bit of the gate. If the reset value has been altered by the bootloader to 0b11 the clock framework will detect the clock as turned on, yet unused, hence it will turn it off and the system locks up. This patch turns the MAX clock on unconditionally making the Kernel independent of the bootloader. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

Fix regression introduced by commit d2323cf773 ("onewire: w1-gpio: add ext_pullup_enable pin in platform data") which added a gpio entry to the platform data, but did not add the required initialisers to the board files using it. Consequently, the driver would request gpio 0 at probe, which could break other uses of the corresponding pin. On AT91 requesting gpio 0 changes the pin muxing for PIOA0, which, for instance, breaks SPI0 on at91sam9g20.

2013-03-12ARM: 7670/1: fix the memset fixNicolas Pitre
Commit 455bd4c430b0 ("ARM: 7668/1: fix memset-related crashes caused by recent GCC (4.7.2) optimizations") attempted to fix a compliance issue with the memset return value. However the memset itself became broken by that patch for misaligned pointers. This fixes the above by branching over the entry code from the misaligned fixup code to avoid reloading the original pointer. Also, because the function entry alignment is wrong in the Thumb mode compilation, that fixup code is moved to the end. While at it, the entry instructions are slightly reworked to help dual issue pipelines.

2013-03-12mfd: ab8500: Kill "reg" property from bindingArnd Bergmann
The ab8500 device is a child of the prcmu device, which is a memory mapped bus device, whose children are addressable using physical memory addresses, not using mailboxes, so a mailbox number in the ab8500 node cannot be parsed by DT. Nothing uses this number, since it was only introduced as part of the failed attempt to clean up prcmu mailbox handling, and we can simply remove it.

2013-03-11xen: arm: mandate EABI and use generic atomic operations.Ian Campbell
Rob Herring has observed that c81611c4e96f "xen: event channel arrays are xen_ulong_t and not unsigned long" introduced a compile failure when building without CONFIG_AEABI: /tmp/ccJaIZOW.s: Assembler messages: /tmp/ccJaIZOW.s:831: Error: even register required -- `ldrexd r5,r6,[r4]' Will Deacon pointed out that this is because OABI does not require even base registers for 64-bit values. We can avoid this by simply using the existing atomic64_xchg operation and the same containerof trick as used by the cmpxchg macros. However since this code is used on memory which is shared with the hypervisor we require proper atomic instructions and cannot use the generic atomic64 callbacks (which are based on spinlocks), therefore add a dependency on !GENERIC_ATOMIC64. Since we already depend on !CPU_V6 there isn't much downside to this. While thinking about this we also observed that OABI has different struct alignment requirements to EABI, which is a problem for hypercall argument structs which are shared with the hypervisor and which must be in EABI layout. Since I don't expect people to want to run OABI kernels on Xen depend on CONFIG_AEABI explicitly too (although it also happens to be enforced by the !GENERIC_ATOMIC64 requirement too).

2013-03-08arm: plat-orion: fix address decoding when > 4GB is usedThomas Petazzoni
During the system initialization, the orion_setup_cpu_mbus_target() function reads the SDRAM address decoding registers to find out how many chip-selects of SDRAM have been enabled, and builds a small array with one entry per chip-select. This array is then used by device drivers (XOR, Ethernet, etc.) to configure their own address decoding windows to the SDRAM. However, devices can only access the first 32 bits of the physical memory. Even though LPAE is not supported for now, some Marvell boards are now showing up with 8 GB of RAM, configured using two SDRAM address decoding windows: the first covering the first 4 GB, the second covering the last 4 GB. The array built by orion_setup_cpu_mbus_target() has therefore two entries, and device drivers try to set up two address decoding windows to the SDRAM. However, in the device registers for the address decoding, the base address is only 32 bits, so those two windows overlap each other, and the devices do not work at all. This patch makes sure that the array built by orion_setup_cpu_mbus_target() only contains the SDRAM decoding windows that correspond to the first 4 GB of the memory. To do that, it ignores the SDRAM decoding windows for which the 4 low-order bits are not zero (the 4 low-order bits of the base register are used to store bits 32:35 of the base address, so they actually indicate whether the base address is above 4 GB). This patch allows the newly introduced armada-xp-gp board to properly operate when it is mounted with more than 4 GB of RAM. Without that, all devices doing DMA (for example XOR and Ethernet) do not work at all.

2013-03-08arm: mvebu: Reduce reg-io-width with UARTsHeikki Krogerus
Setting the reg-io-width to 1 byte represents more accurate description of the HW. This will fix an issue where UART driver causes kernel panic during bootup. Gregory CLEMENT traced the issue to autoconfig() in 8250.c, where the existence of FIFO is checked from UART_IIR register. The register is now read as 32-bit value as the reg-io-width is set to 4-bytes. The retuned value seems to contain bogus data for bits 31:8, causing the issue.
