2010-12-17ARM: mach-shmobile: INTC interrupt priority level demux fixMagnus Damm
Fix interrupt priority level handling on SH-Mobile ARM. SH-Mobile ARM platforms using multiple interrupt priority levels need this patch to fix a potential dead lock that may occur if multiple interrupts with different levels are pending simultaneously. The default INTC configuration is to use the same priority level for all interrupts, so this issue does not trigger by default. It is however common for board code to override the interrupt priority for certain interrupt sources depending on the application. Without this fix such boards may lock up. In detail, this patch updates the INTC code in entry-macro.S to make sure that the INTLVLA register gets set as expected. To trigger this bug modify the board specific code to adjust the interrupt priority level for the ethernet chip. After changing the priority level simply use flood ping to drown the board with interrupts. This patch applies to INTCA-based processors such as sh7372, sh7377 and sh7372. GIC-based processors are not affected. Suitable for v2.6.37-rc and stable from v2.6.34 to v2.6.36.

2010-12-17block: max hardware sectors limit wrapperMike Snitzer
Implement blk_limits_max_hw_sectors() and make blk_queue_max_hw_sectors() a wrapper around it. DM needs this to avoid setting queue_limits' max_hw_sectors and max_sectors directly. dm_set_device_limits() now leverages blk_limits_max_hw_sectors() logic to establish the appropriate max_hw_sectors minimum (PAGE_SIZE). Fixes issue where DM was incorrectly setting max_sectors rather than max_hw_sectors (which caused dm_merge_bvec()'s max_hw_sectors check to be ineffective).

2010-12-17block: Deprecate QUEUE_FLAG_CLUSTER and use queue_limits insteadMartin K. Petersen
When stacking devices, a request_queue is not always available. This forced us to have a no_cluster flag in the queue_limits that could be used as a carrier until the request_queue had been set up for a metadevice. There were several problems with that approach. First of all it was up to the stacking device to remember to set queue flag after stacking had completed. Also, the queue flag and the queue limits had to be kept in sync at all times. We got that wrong, which could lead to us issuing commands that went beyond the max scatterlist limit set by the driver. The proper fix is to avoid having two flags for tracking the same thing. We deprecate QUEUE_FLAG_CLUSTER and use the queue limit directly in the block layer merging functions. The queue_limit 'no_cluster' is turned into 'cluster' to avoid double negatives and to ease stacking. Clustering defaults to being enabled as before. The queue flag logic is removed from the stacking function, and explicitly setting the cluster flag is no longer necessary in DM and MD.

2010-12-16PCI: Update MCP55 quirk to not affect non HyperTransport variantsNeil Horman
I wrote this quirk awhile ago to properly setup MCP55 chips on hypertransport busses so that interrupts reached whatever cpu happend to boot the kdump kernel. while that works well, it was recently shown to me that a a non-hypertransport variant of the MCP55 exists, and on those system the register that this quirk manipulates causes hangs if you write to it. Since the quirk was only meant to handle errors found on MCP55 chips that have a HT interface, this patch adds a filter to make sure the chip is an HT capable before making the needed register adjustment. This lets the broken MCP55s work with kdump while not breaking the non-HT variants. Resolves https://bugzilla.kernel.org/show_bug.cgi?id=23952 Tested successfully by the reporter and myself.

2010-12-16MIPS: LD/SD o32 macro GAS fix updateMaciej W. Rozycki
I am about to commit: http://sourceware.org/ml/binutils/2010-10/msg00033.html that fixes a problem with the LD/SD macro currently implemented by GAS for the o32 ABI in an inconsistent way. This is best illustrated with a simple program, which I'm copying here from the message above for easier reference: $ cat ld.s ld $5,32767($4) ld $5,32768($4) This gets assebled into the following output: $ mips-linux-as -32 -mips3 -o ld.o ld.s $ mips-linux-objdump -d ld.o ld.o: file format elf32-tradbigmips Disassembly of section .text: 00000000 <.text>: 0: dc857fff ld a1,32767(a0) 4: 3c010001 lui at,0x1 8: 00810821 addu at,a0,at c: 8c258000 lw a1,-32768(at) 10: 8c268004 lw a2,-32764(at) ... Oops! The GAS fix makes the macro behave in a consistent way and pairs of LW/SW instructions to be output as appropriate regardless of the size of the offset associated with the address used. The machine instruction is still available, but to reach it macros have to be disabled first. This has a side effect of requiring the use of a machine-addressable memory operand. As some platforms require 64-bit operations for accesses to some I/O registers LD/SD instructions are used in a couple of places in Linux regardless of the ABI selected. Here's a fix for some pieces of code affected I've been able to track down. The fix should be backwards compatible with all supported binutils releases in existence and can be used as a reference for any other places or off-tree code. The use of the "R" constraint guarantees a machine-addressable operand. Signed-off-by: Maciej W.

Use nvram_getenv function, which is in mainline and use an include instead of an extra function declaration. et0macaddr contains the mac address in text from like 00:11:22:33:44:55. We have to parse it before adding it into macaddr. nvram_parse_macaddr will be merged into asm/mach-bcm47xx/nvram.h through the MIPS git tree and will be available soon.

2010-12-16MIPS: Fix CP0 COUNTER clockevent raceKevin Cernekee
Consider the following test case: write_c0_compare(read_c0_count()); Even if the counter doesn't increment during execution, this might not generate an interrupt until the counter wraps around. The CPU may perform the comparison each time CP0 COUNT increments, not when CP0 COMPARE is written. If mips_next_event() is called with a very small delta, and CP0 COUNT increments during the calculation of "cnt += delta", it is possible that CP0 COMPARE will be written with the current value of CP0 COUNT. If this is detected, the function should return -ETIME, to indicate that the interrupt might not have actually gotten scheduled.

2010-12-16MIPS: Separate two consecutive loads in memset.STony Wu
partial_fixup is used in noreorder block. Separating two consecutive loads can save one cycle on processors with GPR intrelock and can fix load-use on processors that need a load delay slot. Also do so for fwd_fixup. [Ralf: Only R2000/R3000 class processors are lacking the the load-user interlock and even some of those got it retrofitted. With R2000/R3000 being fairly uncommon these days the impact of this bug should be minor.] Signed-off-by: Tony Wu <tung7970@gmail.com> To: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/1768/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
