2013-05-06Merge branch 'late/clksrc' into late/cleanupArnd Bergmann353-4947/+15263
There is no reason to keep the clksrc cleanups separate from the other cleanups, and this resolves some merge conflicts. Conflicts: arch/arm/mach-spear/spear13xx.c drivers/irqchip/Makefile

This is support for the ARM Chromebook, originally scheduled as a "late" pull request. Since it's already late now, we can combine this into the existing next/dt2 branch. * late/dt: ARM: exynos: dts: cros5250: add EC device ARM: dts: Add sbs-battery for exynos5250-snow ARM: dts: Add i2c-arbitrator bus for exynos5250-snow ARM: dts: Add chip-id controller node on Exynos4/5 SoC ARM: EXYNOS: Create virtual I/O mapping for Chip-ID controller using device tree

2013-05-06parisc: use long branch in fork_like macroJohn David Anglin1-1/+2
The "b" branch instruction used in the fork_like macro only can handle 17-bit pc-relative offsets. This fails with an out of range offset with some .config files.

2013-05-06parisc: fix partly 16/64k PAGE_SIZE bootHelge Deller6-25/+52
This patch fixes partly PAGE_SIZEs of 16K or 64K by adjusting the assembler PTE lookup code and the assembler TEMPALIAS code. Furthermore some data alignments for PAGE_SIZE have been limited to 4K (or less) to not waste too much memory with greater page sizes. As a side note, the palo loader can (currently) only handle up to 10 ELF segments which is fixed with tighter aligning as well. My testings indicated that the ldci command in the sba iommu coding needed adjustment by the PAGE_SHIFT value and that the I/O PDIR Page size was only set to 4K for my machine (C3000). All this fixes partly the boot, but there are still quite some caching problems left. Examples are e.g. the symbios logic driver which is failing: sym0: <896> rev 0x7 at pci 0000:00:0f.0 irq 69 sym0: PA-RISC Firmware, ID 7, Fast-40, SE, parity checking CACHE TEST FAILED: DMA error (dstat=0x81).sym0: CACHE INCORRECTLY CONFIGURED. and the tulip network driver which doesn't seem to work correctly either: Sending BOOTP requests .net eth0: Setting full-duplex based on MII#1 link partner capability of 05e1 ..... timed out! Beside those kernel fixes glibc will need fixes too to be able to handle >4K page sizes. Signed-off-by: Helge Deller <[email protected]>

2013-05-06autofs - remove autofs dentry mount checkDavid Jeffery1-9/+0
When checking if an autofs mount point is busy it isn't sufficient to only check if it's a mount point. For example, if the mount of an offset mountpoint in a tree is denied for this host by its export and the dentry becomes a process working directory the check incorrectly returns the mount as not in use at expire. This can happen since the default when mounting within a tree is nostrict, which means ingnore mount fails on mounts within the tree and continue. The nostrict option is meant to allow mounting in this case.

When unloading the driver that drives an EISA board, a message similar to the following one is displayed: Trying to free nonexistent resource <0000000000013000-000000000001301f> Then an user is unable to reload the driver because the resource it requested in the previous load hasn't been freed.

2013-05-06net: frag, fix race conditions in LRU list maintenanceKonstantin Khlebnikov2-2/+4
This patch fixes race between inet_frag_lru_move() and inet_frag_lru_add() which was introduced in commit 3ef0eb0db4bf92c6d2510fe5c4dc51852746f206 ("net: frag, move LRU list maintenance outside of rwlock") One cpu already added new fragment queue into hash but not into LRU. Other cpu found it in hash and tries to move it to the end of LRU. This leads to NULL pointer dereference inside of list_move_tail(). Another possible race condition is between inet_frag_lru_move() and inet_frag_lru_del(): move can happens after deletion. This patch initializes LRU list head before adding fragment into hash and inet_frag_lru_move() doesn't touches it if it's empty. I saw this kernel oops two times in a couple of days.

2013-05-06powerpc/pci: Support per-aperture memory offsetBenjamin Herrenschmidt10-104/+54
The PCI core supports an offset per aperture nowadays but our arch code still has a single offset per host bridge representing the difference betwen CPU memory addresses and PCI MMIO addresses. This is a problem as new machines and hypervisor versions are coming out where the 64-bit windows will have a different offset (basically mapped 1:1) from the 32-bit windows. This fixes it by using separate offsets. In the long run, we probably want to get rid of that intermediary struct pci_controller and have those directly stored into the pci_host_bridge as they are parsed but this will be a more invasive change.

2013-05-06powerpc/cell/iommu: Improve error message for missing nodeBenjamin Herrenschmidt1-1/+1
Some devices don't have a correct node ID and thus can't be attached to an iommu. The message displayed by the iommu code isn't very useful if you don't have a device-tree node as it tries to print the device-tree path but not the struct device name. Improve this by printing the device name as well. Signed-off-by: Benjamin Herrenschmidt <[email protected]>
2013-05-06powerpc/cell/spufs: Fix status attribute permissionBenjamin Herrenschmidt1-1/+1
We are registering the attribute with permission 0644 but it doesn't have a store callback, which causes WARN_ON's during boot. Fix the permission. Signed-off-by: Benjamin Herrenschmidt <[email protected]>
2013-05-06irqdomain: Allow quiet failure modeBenjamin Herrenschmidt2-6/+28
Some interrupt controllers refuse to map interrupts marked as "protected" by firwmare. Since we try to map everyting in the device-tree on some platforms, we end up with a lot of nasty WARN's in the boot log for what is a normal situation on those machines. This defines a specific return code (-EPERM) from the host map() callback which cause irqdomain to fail silently. MPIC is updated to return this when hitting a protected source printing only a single line message for diagnostic purposes. Signed-off-by: Benjamin Herrenschmidt <[email protected]>

git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-next Pull MFD update from Samuel Ortiz: "For 3.10 we have a few new MFD drivers for: - The ChromeOS embedded controller which provides keyboard, battery and power management services. This controller is accessible through i2c or SPI. - Silicon Laboratories 476x controller, providing access to their FM chipset and their audio codec. - Realtek's RTS5249, a memory stick, MMC and SD/SDIO PCI based reader. - Nokia's Tahvo power button and watchdog device. This device is very similar to Retu and is thus supported by the same code base. - STMicroelectronics STMPE1801, a keyboard and GPIO controller supported by the stmpe driver. - ST-Ericsson AB8540 and AB8505 power management and voltage converter controllers through the existing ab8500 code. Some other drivers got cleaned up or improved. In particular: - The Linaro/STE guys got the ab8500 driver in sync with their internal code through a series of optimizations, fixes and improvements. - The AS3711 and OMAP USB drivers now have DT support. - The arizona clock and interrupt handling code got improved. - The wm5102 register patch and boot mechanism also got improved." * tag 'mfd-3.10-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-next: (104 commits) mfd: si476x: Don't use 0bNNN mfd: vexpress: Handle pending config transactions mfd: ab8500: Export ab8500_gpadc_sw_hw_convert properly mfd: si476x: Fix i2c warning mfd: si476x: Add header files and Kbuild plumbing mfd: si476x: Add chip properties handling code mfd: si476x: Add the bulk of the core driver mfd: si476x: Add commands abstraction layer mfd: rtsx: Support RTS5249 mfd: retu: Add Tahvo support mfd: ucb1400: Pass ucb1400-gpio data through ac97 bus mfd: wm8994: Add some OF properties mfd: wm8994: Add device ID data to WM8994 OF device IDs input: Export matrix_keypad_parse_of_params() mfd: tps65090: Add compatible string for charger subnode mfd: db8500-prcmu: Support platform dependant device selection mfd: syscon: Fix warnings when printing resource_size_t of: Add stub of_get_parent for non-OF builds mfd: omap-usb-tll: Convert to devm_ioremap_resource() mfd: omap-usb-host: Convert to devm_ioremap_resource() ...

2013-05-06powerpc/pseries: Perform proper max_bus_speed detectionKleber Sacilotto de Souza5-0/+70
On pseries machines the detection for max_bus_speed should be done through an OpenFirmware property. This patch adds a function to perform this detection and a hook to perform dynamic adding of the function only for pseries. This is done by overwriting the weak pcibios_root_bridge_prepare function which is called by pci_create_root_bus().

The following patch implements a new PAPR change which allows the OS to force the use of 32 bit MSIs, regardless of what the PCI capabilities indicate. This is required for some devices that advertise support for 64 bit MSIs but don't actually support them.
