2006-12-07[ARM] 3983/2: remove unused argument to __bug()Nicolas Pitre1-2/+2
It appears that include/asm-arm/bug.h requires include/linux/stddef.h for the definition of NULL. It seems that stddef.h was always included indirectly in most cases, and that issue was properly fixed a while ago. Then commit 5047f09b56d0bc3c21aec9cb16de60283da645c6 incorrectly reverted change from commit ff10952a547dad934d9ed9afc5cf579ed1ccb53a (bad dwmw2) and the problem recently resurfaced. Because the third argument to __bug() is never used anyway, RMK suggested getting rid of it entirely instead of readding #include <linux/stddef.h> which this patch does.

2006-12-07[IA64] Fix DISCONTIGMEM without VIRTUAL_MEM_MAPMatthew Wilcox1-6/+5
make allnoconfig currently fails to build because it selects DISCONTIGMEM without VIRTUAL_MEM_MAP. I see no particular reason this combination ought to fail, so I fixed it by: - Including memory_model.h in all circumstances, except when both DISCONTIGMEM and VIRTUAL_MEM_MAP are enabled. - Defining ia64_pfn_valid() to 1 unless VIRTUAL_MEM_MAP is enabled Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: Tony Luck <tony.luck@intel.com>
2006-12-07[PATCH] Add support for type argument in PAL_GET_PSTATEVenkatesh Pallipadi1-2/+7
PAL_GET_PSTATE accepts a type argument to return different kinds of frequency information. Refer: Intel Itanium®Architecture Software Developer's Manual - Volume 2: System Architecture, Revision 2.2 (http://developer.intel.com/design/itanium/manuals/245318.htm) Add the support for type argument and use Instantaneous frequency in the acpi driver. Also fix a bug, where in return value of PAL_GET_PSTATE was getting compared with 'control' bits instead of 'status' bits.

2006-12-07Add "run_scheduled_work()" workqueue functionLinus Torvalds1-0/+1
This allows workqueue users to run just their own pending work, rather than wait for the whole workqueue to finish running. This solves the deadlock with networking libphy that was due to other workqueue entries possibly needing a lock that was held by the routine that wanted to flush its own work. It's not wonderful: if you absolutely need to synchronize with the work function having been executed, any user strictly speaking should have its own completion tracking logic, since when we run things explicitly by hand, the generic workqueue layer can no longer help us synchronize. Also, this is strictly only usable for work that has been scheduled without any delayed timers. You can not mix the new interface with schedule_delayed_work(). But it's better than what we had currently. Acked-by: Maciej W. Rozycki <macro@linux-mips.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-12-07[ARM] 3995/1: iop13xx: add iop13xx supportDan Williams14-0/+1078
The iop348 processor integrates an Xscale (XSC3 512KB L2 Cache) core with a Serial Attached SCSI (SAS) controller, multi-ported DDR2 memory controller, 3 Application Direct Memory Access (DMA) controllers, a 133Mhz PCI-X interface, a x8 PCI-Express interface, and other peripherals to form a system-on-a-chip RAID subsystem engine. The iop342 processor replaces the SAS controller with a second Xscale core for dual core embedded applications. The iop341 processor is the single core version of iop342. This patch supports the two Intel customer reference platforms iq81340mc for external storage and iq81340sc for direct attach (HBA) development.

2006-12-07[PATCH] IPMI: Fix BT long busyCorey Minyard1-2/+6
The IPMI BT subdriver has been patched to survive "long busy" timeouts seen during firmware upgrades and resets. The patch never returns the HOSED state, synthesizes response messages with meaningful completion codes, and recovers gracefully when the hardware finishes the long busy. The subdriver now issues a "Get BT Capabilities" command and properly uses those results. More informative completion codes are returned on error from transaction starts; this logic was propogated to the KCS and SMIC subdrivers. Finally, indent and other style quirks were normalized.

2006-12-07[PATCH] IPMI: Add maintenance modeCorey Minyard3-0/+57
Some commands and operations on a BMC can cause the BMC to "go away" for a while. This can cause the automatic flag processing and other things of that nature to timeout and generate annoying logs, or possibly cause other bad things to happen when in firmware update mode. Add detection of those commands (cold reset, warm reset, and any firmware command) and turns off automatic processing for 30 seconds. It also add a manual override either way.

Remove the ki_retried member from struct kiocb. I think the idea was bounced around a while back, but Arnaldo pointed out another reason that we should dig it up when he pointed out that the last cacheline of struct kiocb only contains 4 bytes. By removing the debugging member, we save more than the 8 byte on 64 bit machines.

2006-12-07[PATCH] Kexec / Kdump: Unify elf note codeMagnus Damm1-0/+1
The elf note saving code is currently duplicated over several architectures. This cleanup patch simply adds code to a common file and then replaces the arch-specific code with calls to the newly added code. The only drawback with this approach is that s390 doesn't fully support kexec-on-panic which for that arch leads to introduction of unused code.

Pass struct dev pointer to dma_cache_sync() dma_cache_sync() is ill-designed in that it does not have a struct device pointer argument which makes proper support for systems that consist of a mix of coherent and non-coherent DMA devices hard.

2006-12-07[PATCH] fs: reorder some 'struct inode' fields to speedup i_size manipulationsEric Dumazet1-4/+4
On 32bits SMP platforms, 64bits i_size is protected by a seqcount (i_size_seqcount). When i_size is read or written, i_size_seqcount is read/written as well, so it make sense to group these two fields together in the same cache line. This patch moves i_size_seqcount next to i_size, and also moves i_version to let offsetof(struct inode, i_size) being 0x40 instead of 0x3c (for 32bits platforms). For 64 bits platforms, i_size_seqcount doesnt exist, and the move of a 'long i_version' should not introduce a new hole because of padding.
