linux/arch/tile/kernel/setup.c, branch v3.4-rc2

Merge branch 'stable' of git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile

2012-04-07T00:56:20Z

Pull arch/tile bug fixes from Chris Metcalf: "This includes Paul Gortmaker's change to fix the disintegration issues on tile, a fix to unbreak the tilepro ethernet driver, and a backlog of bugfix-only changes from internal Tilera development over the last few months. They have all been to LKML and on linux-next for the last few days. The EDAC change to MAINTAINERS is an oddity but discussion on the linux-edac list suggested I ask you to pull that change through my tree since they don't have a tree to pull edac changes from at the moment." * 'stable' of git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile: (39 commits) drivers/net/ethernet/tile: fix netdev_alloc_skb() bombing MAINTAINERS: update EDAC information tilepro ethernet driver: fix a few minor issues tile-srom.c driver: minor code cleanup edac: say "TILEGx" not "TILEPro" for the tilegx edac driver arch/tile: avoid accidentally unmasking NMI-type interrupt accidentally arch/tile: remove bogus performance optimization arch/tile: return SIGBUS for addresses that are unaligned AND invalid arch/tile: fix finv_buffer_remote() for tilegx arch/tile: use atomic exchange in arch_write_unlock() arch/tile: stop mentioning the "kvm" subdirectory arch/tile: export the page_home() function. arch/tile: fix pointer cast in cacheflush.c arch/tile: fix single-stepping over swint1 instructions on tilegx arch/tile: implement panic_smp_self_stop() arch/tile: add "nop" after "nap" to help GX idle power draw arch/tile: use proper memparse() for "maxmem" options arch/tile: fix up locking in pgtable.c slightly arch/tile: don't leak kernel memory when we unload modules arch/tile: fix bug in delay_backoff() ...

arch/tile: use proper memparse() for "maxmem" options

2012-04-02T16:13:25Z

This is more standard and avoids having to remember what units the options actually take. Signed-off-by: Chris Metcalf

arch/tile: fix a couple of comments that needed updating

Not associated with any code changes, so I'm just lumping these comment changes into a commit by themselves. Signed-off-by: Chris Metcalf

documentation: remove references to cpu_*_map.

This has been obsolescent for a while, fix documentation and misc comments. Signed-off-by: Rusty Russell

remove references to cpu_*_map in arch/

2012-03-29T05:08:30Z

This has been obsolescent for a while; time for the final push. In adjacent context, replaced old cpus_* with cpumask_*. Signed-off-by: Rusty Russell Acked-by: David S.

treewide: Convert uses of struct resource to resource_size(ptr)

2011-06-10T12:55:36Z

Several fixes as well where the +1 was missing. Done via coccinelle scripts like: @@ struct resource *ptr; @@ - ptr->end - ptr->start + 1 + resource_size(ptr) and some grep and typing. Mostly uncompiled, no cross-compilers. Signed-off-by: Joe Perches Signed-off-by: Jiri Kosina

arch/tile: tolerate disabling CONFIG_BLK_DEV_INITRD

2011-05-04T18:40:36Z

The code accidentally was relying on this configuration option being selected. Signed-off-by: Chris Metcalf

arch/tile: support 4KB page size as well as 64KB

2011-03-10T18:17:53Z

The Tilera architecture traditionally supports 64KB page sizes to improve TLB utilization and improve performance when the hardware is being used primarily to run a single application. For more generic server scenarios, it can be beneficial to run with 4KB page sizes, so this commit allows that to be specified (by modifying the arch/tile/include/hv/pagesize.h header). As part of this change, we also re-worked the PTE management slightly so that PTE writes all go through a __set_pte() function where we can do some additional validation. The set_pte_order() function was eliminated since the "order" argument wasn't being used. One bug uncovered was in the PCI DMA code, which wasn't properly flushing the specified range. This was benign with 64KB pages, but with 4KB pages we were getting some larger flushes wrong. The per-cpu memory reservation code also needed updating to conform with the newer percpu stuff; before it always chose 64KB, and that was always correct, but with 4KB granularity we now have to pay closer attention and reserve the amount of memory that will be requested when the percpu code starts allocating.

arch/tile: make glibc's sysconf(_SC_NPROCESSORS_CONF) work correctly

2010-11-24T18:42:15Z

glibc assumes that it can count /sys/devices/system/cpu/cpu* to get the number of configured cpus. For this to be valid on tile, we need to generate a "cpu" entry for all cpus, including the ones that are not currently allocated for Linux's use. Signed-off-by: Chris Metcalf

arch/tile: bomb raw_local_irq_ to arch_local_irq_

2010-11-01T19:30:42Z

This completes the tile migration to the new naming scheme for the architecture-specific irq management code. Signed-off-by: Chris Metcalf
