arch: tile: re-use kbasename() helper

2013-09-30T14:34:46Z

kbasename() returns the filename part of a pathname. Signed-off-by: Andy Shevchenko

tile: ensure interrupts disabled for preempt_schedule_irq()

2013-09-27T20:09:43Z

When coming from a page fault (for example), interrupts might be enabled as we enter the code to return from interrupt. Cc: stable@vger.kernel.org Signed-off-by: Chris Metcalf

tile: change lock initalization in hardwall

2013-09-27T20:09:38Z

hardwall used __SPIN_LOCK_INITIALIZER directly instead of the preferred __SPIN_LOCK_UNLOCKED. This also has the benefit that it will compile when applying the preempt-rt patch series. Signed-off-by: Henrik Austad Signed-off-by: Chris Metcalf

tile: remove stray blank space

2013-09-16T19:47:32Z

The compat sys_llseek() definition addition added a bogus space on an otherwise-blank line. Signed-off-by: Chris Metcalf

tile: remove stale arch/tile/kernel/futex_64.S

2013-09-13T15:15:24Z

This should have been removed with commit 47d632f9f8f3, but it was overlooked. Signed-off-by: Chris Metcalf

tile: remove HUGE_VMAP dead code

2013-09-13T15:15:24Z

A config option to allow a variant vmap() using huge pages that was never upstreamed had some bits of code related to it scattered around the tile architecture; the config option was removed downstream and this commit cleans up the scattered evidence of it from the upstream as well.

Pull Tile arch updates from Chris Metcalf: "These changes bring in a bunch of new functionality that has been maintained internally at Tilera over the last year, plus other stray bits of work that I've taken into the tile tree from other folks. The changes include some PCI root complex work, interrupt-driven console support, support for performing fast-path unaligned data fixups by kernel-based JIT code generation, CONFIG_PREEMPT support, vDSO support for gettimeofday(), a serial driver for the tilegx on-chip UART, KGDB support, more optimized string routines, support for ftrace and kprobes, improved ASLR, and many bug fixes. We also remove support for the old TILE64 chip, which is no longer buildable" * git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile: (85 commits) tile: refresh tile defconfig files tile: rework tile PCI RC: make default consistent DMA mask 32-bit tile: add null check for kzalloc in tile/kernel/setup.c tile: make __write_once a synonym for __read_mostly tile: remove support for TILE64 tile: use asm-generic/bitops/builtin-*.h tile: eliminate no-op "noatomichash" boot argument tile: use standard tile_bundle_bits type in traps.c tile: simplify code referencing hypervisor API addresses tile: change to in comments tile: mark pcibios_init() as __init tile: check for correct compiler earlier in asm-offsets.c tile: use standard 'generic-y' model for tile: use asm-generic version of tile PCI RC: add comment about "PCI hole" problem tile: remove DEBUG_EXTRA_FLAGS kernel config option tile: add virt_to_kpte() API and clean up and document behavior tile: support FRAME_POINTER tile: support reporting Tilera hypervisor statistics ...

tile PCI RC: make default consistent DMA mask 32-bit

2013-09-03T18:53:37Z

This change sets the PCI devices' initial DMA capabilities conservatively and promotes them at the request of the driver, as opposed to assuming advanced DMA capabilities. The old design runs the risk of breaking drivers that assume default capabilities. Signed-off-by: Chris Metcalf

tile: add null check for kzalloc in tile/kernel/setup.c

2013-09-03T18:53:34Z

Should check the return value of kzalloc first to avoid the null pointer. Then can dereference the non-null pointer to access the fields of struct resource. Signed-off-by: Wang Sheng-Hui Signed-off-by: Chris Metcalf
