2007-05-21sh: sr.bl toggling around idle sleep.Paul Mundt
As pointed out by Saito-san, without the sr.bl manipulation we can occasionally hit delays in the idle loop due to interrupt handling, so ensure that interrupts are blocked before going to sleep. At the same time, we throw in TIF_POLLING_NRFLAG for the !hlt_counter case (primarily used by the ST-40 parts). Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2007-05-21sh: revert addition of page fault notifiersChristoph Hellwig
Just at the time you added them on sh we're removing them from other architectures. As there's no user yet this patch just removes them completely. Once you actually have a kprobes patch it should follow the direct call to kprobes_fault_handler model that powerpc, s390 and sparc64 employ in 2.6.22-rc1 and that I'm updating other architectures to.

2007-05-17Revert "[PATCH] x86: Drop cc-options call for all options supported in gcc 3.2+"Linus Torvalds
This reverts commit c8fdd247255a3a027cd9f66dcf93e6847d1d2f85. It turns out the kernel was correct, and the gcc complaint was a gcc bug. The preferred stack boundary is expressed not in bytes, but in the the log2() of the preferred boundary, so "-mpreferred-stack-boundary=2" is in fact exactly what we want, but a gcc that is compiled for x86-64 will consider it an error (because the 64-bit calling sequence says that the stack should be 16-byte aligned) even if we are then using "-m32" to generate 32-bit code.

2007-05-17Slab allocators: define common size limitationsChristoph Lameter
Currently we have a maze of configuration variables that determine the maximum slab size. Worst of all it seems to vary between SLAB and SLUB. So define a common maximum size for kmalloc. For conveniences sake we use the maximum size ever supported which is 32 MB. We limit the maximum size to a lower limit if MAX_ORDER does not allow such large allocations. For many architectures this patch will have the effect of adding large kmalloc sizes. x86_64 adds 5 new kmalloc sizes. So a small amount of memory will be needed for these caches (contemporary SLAB has dynamically sizeable node and cpu structure so the waste is less than in the past) Most architectures will then be able to allocate object with sizes up to MAX_ORDER. We have had repeated breakage (in fact whenever we doubled the number of supported processors) on IA64 because one or the other struct grew beyond what the slab allocators supported. This will avoid future issues and f.e. avoid fixes for 2k and 4k cpu support. CONFIG_LARGE_ALLOCS is no longer necessary so drop it. It fixes sparc64 with SLAB.

2007-05-17[POWERPC] Pass per-file CFLAGs for platform specific op codesJosh Boyer
As a result of compiling all of the wrapper files for every platform now, the kernel build can fail for toolchains that don't support various op codes by default. An example of this building a 7xx platform with the ELD4.0 toolchain, is below: /tmp/ccYjhJoL.s: Assembler messages: /tmp/ccYjhJoL.s:42: Error: Unrecognized opcode: `mtdcr' /tmp/ccYjhJoL.s:43: Error: Unrecognized opcode: `mfdcr' make[1]: *** [arch/powerpc/boot/44x.o] Error 1 The following patch introduces additional CFLAGS for the 4xx specific files and fixes the kernel compile.

Our device-tree unflattening code makes sure the name and type fields of a device-node are not NULL.

2007-05-17[POWERPC] Small fixes for the Ebony device treeDavid Gibson
This patch corrects a number of minor errors in the Ebony device tree: - Missing (given as 0) cache sizes are added to the CPU node - device_type properties are removed from nodes which don't have a reasonably well defined device_type binding. This does require a very small code change to locate the busses to be probed for of_platform devices by 'compatible' instead of 'device_type'. - A node is added for the SRAM controller - The unit address of the small-flash node is adjusted to correctly reflect the reg property. - device_type values for the MAL and ZMII are updated to reflected more up-to-date versions of the binding. - An incorrect offset in the partition map for the large-flash node is corrected. - Some redundant values, already commented out are removed entirely.

2007-05-17[POWERPC] Fix IO space on PCI buses created from of_platformBenjamin Herrenschmidt
This changes the way of_platform_pci creates PCI host bridges such that it uses request_phb_iospace() for mapping the IO ports, instead of using the dynamic hotplug stuff. That guarantees the IO space stays within the 2GB limit and thus doesn't break half of the legacy drivers around. Fixes a couple of warnings due to missing IO space while at it.

2007-05-17[POWERPC] Fix bug adding properties with flatdevtree.c's ft_set_prop()David Gibson
ft_set_prop() from flatdevtree.c in the zImage wrapper will either replace an existing property in the flat device tree, or add a new property definiion if the given property isn't present. However, when adding properties, it adds the property definition immediately before the node's END_NODE tag, potentially after any subnode definitions for the node. This confuses the kernel flat tree parser in prom.c which assumes that all property definitions for a node come before all subnode definitions. This patch corrects ft_set_prop() so that it adds new properties before the first subnode, instead of before the END_NODE tag.
