2012-07-27ARM: Kirkwood: Add basic device tree support for QNAP TS219.Andrew Lunn9-0/+228
The two different variants of QNAP TS devices, varying by SoC, put the GPIO keys on different GPIO lines. Hence we need two different DT board descriptions, which share the same board-ts219.c file. Signed-off-by: Andrew Lunn <[email protected]> Acked-by: Jason Cooper <[email protected]>
2012-07-27ATA: sata_mv: Add device tree supportAndrew Lunn2-0/+8
Add support for instantiating this driver from device tree, and add the necassary DT information to the kirkwood.dtsi file. This is based on previous work by Michael Walle and Jason Cooper. Signed-off-by: Andrew Lunn <[email protected]> Tested-by: Josh Coombs <[email protected]>
2012-07-27ARM: Orion: DTify the watchdog timer.Andrew Lunn2-1/+7
Add device tree support to the Orion watchdog timer, and enable its use in the kirkwood devices using device tree. Signed-off-by: Andrew Lunn <[email protected]> Acked-by: Sebastian Hesselbarth <[email protected]> Tested-by: Simon Baatz <[email protected]>
2012-07-27ARM: Orion: Add arch support needed for I2C via DT.Andrew Lunn4-0/+15
The MV64XXX I2C driver needs a clock in order to calculate the baud rate factors. So add an clk to the clk tree. Also add the base DT properties for kirkwood devices. Signed-off-by: Andrew Lunn <[email protected]> Conflicts: arch/arm/mach-kirkwood/common.c

2012-07-27ARM: Orion: DT support for IRQ and GPIO ControllersAndrew Lunn11-132/+264
Both IRQ and GPIO controllers can now be represented in DT. The IRQ controllers are setup first, and then the GPIO controllers. Interrupts for GPIO lines are placed directly after the main interrupts in the interrupt space.

2012-07-27powerpc/ftrace: Trace function graph entry before updating indexSteven Rostedt1-6/+5
As Colin Cross ported my x86 change to ARM, he also pointed out that powerpc is also behind in this fix. The commit 722b3c746953 "ftrace/graph: Trace function entry before updating index" fixes an issue with function graph tracing for x86, where if the called entry function decides not to trace interrupts, it can fail the check if an interrupt comes in just after the curr_ret_stack is updated. The solution is to call the entry function first, then update the curr_ret_stack if the entry function wants to be traced.

This updates the g5 defconfig to include nouveau instead of nvidiafb (which works much better nowadays, in fact the latter crashes on modern distros), and to set CONFIG_VT_HW_CONSOLE_BINDING without which takeover from the firmware offb by nouveau doesn't work properly (and leads to unexplained black screens for some users).

2012-07-26posix_types.h: Cleanup stale __NFDBITS and related definitionsJosh Boyer1-1/+1
Recently, glibc made a change to suppress sign-conversion warnings in FD_SET (glibc commit ceb9e56b3d1). This uncovered an issue with the kernel's definition of __NFDBITS if applications #include <linux/types.h> after including <sys/select.h>. A build failure would be seen when passing the -Werror=sign-compare and -D_FORTIFY_SOURCE=2 flags to gcc. It was suggested that the kernel should either match the glibc definition of __NFDBITS or remove that entirely. The current in-kernel uses of __NFDBITS can be replaced with BITS_PER_LONG, and there are no uses of the related __FDELT and __FDMASK defines. Given that, we'll continue the cleanup that was started with commit 8b3d1cda4f5f ("posix_types: Remove fd_set macros") and drop the remaining unused macros. Additionally, linux/time.h has similar macros defined that expand to nothing so we'll remove those at the same time.

2012-07-26powerpc/85xx: p1022ds: fix DIU/LBC switching with NAND enabledTimur Tabi1-2/+62
In order for indirect mode on the PIXIS to work properly, both chip selects need to be set to GPCM mode, otherwise writes to the chip select base addresses will not actually post to the local bus -- they'll go to the NAND controller instead. Therefore, we need to set BR0 and BR1 to GPCM mode before switching to indirect mode. Signed-off-by: Timur Tabi <[email protected]> Signed-off-by: Kumar Gala <[email protected]>
2012-07-26powerpc/85xx: p1022ds: disable the NAND flash node if video is enabledTimur Tabi1-20/+38
The Freescale P1022 has a unique pin muxing "feature" where the DIU video controller's video signals are muxed with 24 of the local bus address signals. When the DIU is enabled, the bulk of the local bus is disabled, preventing access to memory-mapped devices like NAND flash and the pixis FPGA. Therefore, if the DIU is going to be enabled, then memory-mapped devices on the localbus, like NAND flash, need to be disabled. This patch is similar to "powerpc/85xx: p1022ds: disable the NOR flash node if video is enabled", except that it disables the NAND flash node instead. This PIXIS node needs to remain enabled because it is used by platform code to switch into indirect mode. Signed-off-by: Timur Tabi <[email protected]> Signed-off-by: Kumar Gala <[email protected]>
2012-07-26powerpc/85xx: Fix sram_offset parameter typeClaudiu Manoil2-27/+16
The sram_offset parameter represents a physical address and should be of type phys_addr_t. As part of this fix, the extraction of sram_params is being cleaned-up and fixed. This patch fixes now the case when the offset value of 0xfff00000 was being rejected by the driver (returning -EINVAL), although this is a valid offset value.

2012-07-26[IA64] Redefine ATOMIC_INIT and ATOMIC64_INIT to drop the castsTony Luck1-2/+2
The following build error occured during a ia64 build with swap-over-NFS patches applied. net/core/sock.c:274:36: error: initializer element is not constant net/core/sock.c:274:36: error: (near initialization for 'memalloc_socks') net/core/sock.c:274:36: error: initializer element is not constant This is identical to a parisc build error. Fengguang Wu, Mel Gorman and James Bottomley did all the legwork to track the root cause of the problem. This fix and entire commit log is shamelessly copied from them with one extra detail to change a dubious runtime use of ATOMIC_INIT() to atomic_set() in drivers/char/mspec.c Dave Anglin says: > Here is the line in sock.i: > > struct static_key memalloc_socks = ((struct static_key) { .enabled = > ((atomic_t) { (0) }) }); The above line contains two compound literals. It also uses a designated initializer to initialize the field enabled. A compound literal is not a constant expression. The location of the above statement isn't fully clear, but if a compound literal occurs outside the body of a function, the initializer list must consist of constant expressions.

2012-07-26s390/mm: downgrade page table after fork of a 31 bit processMartin Schwidefsky4-8/+25
The downgrade of the 4 level page table created by init_new_context is currently done only in start_thread31. If a 31 bit process forks the new mm uses a 4 level page table, including the task size of 2<<42 that goes along with it. This is incorrect as now a 31 bit process can map memory beyond 2GB. Define arch_dup_mmap to do the downgrade after fork. Cc: [email protected] Signed-off-by: Martin Schwidefsky <[email protected]>
