| * [POWERPC] Pass per-file CFLAGs for platform specific op codesJosh Boyer2007-05-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * [POWERPC] Make sure device node type/name is not NULL on hot-added nodesBenjamin Herrenschmidt2007-05-17
| | | | | | | | | | | | | | | | | | | | | | Our device-tree unflattening code makes sure the name and type fields of a device-node are not NULL. However, the code for dynamically adding devices nodes which is used for pSeries hotplug for example didn't do it, potentially causing crashes in some code that assume it can always do things like strcmp on those.

| * [POWERPC] Small fixes for the Ebony device treeDavid Gibson2007-05-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * [POWERPC] Fix IO space on PCI buses created from of_platformBenjamin Herrenschmidt2007-05-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * [POWERPC] Fix bug adding properties with flatdevtree.c's ft_set_prop()David Gibson2007-05-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

* | Slab allocators: define common size limitationsChristoph Lameter2007-05-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

So add a small set of interfaces to request API versions and query current settings. This allows us to fix some bugs in the hypervisor console: 1) If we can negotiate API group CORE of at least major 1 minor 1 we can use con_read and con_write which can improve console performance quite a bit. 2) When we do a console write request, we should hold the spinlock around the whole request, not a byte at a time. What would happen is that it's easy for output from different cpus to get mixed with each other. 3) Use consistent udelay() based polling, udelay(1) each loop with a limit of 1000 polls to handle stuck hypervisor console.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Get rid of the notifier list and call the kprobes code directly if compiled in. This mirrors the changes that recently went into powerpc, s390 and sparc64. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Tony Luck <tony.luck@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Building with GCC 4.2, I get the following error: CC arch/ia64/kernel/mca.o arch/ia64/kernel/mca.c:275: error: __ksymtab_ia64_mlogbuf_finish causes a section type conflict This is because ia64_mlogbuf_finish is both declared static and exported. Fix by removing the export (which is unneeded now). Signed-off-by: Martin Michlmayr <tbm@cyrius.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

| * | [IA64] kdump on INIT needs multi-nodes sync-up (v.2)Jay Lan2007-05-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current implementation of kdump on INIT events would enter kdump processing on DIE_INIT_MONARCH_ENTER and DIE_INIT_SLAVE_ENTER events. Thus, the monarch cpu would go ahead and boot up the kdump On SN shub2 systems, this out-of-sync situation causes some slave cpus on different nodes to enter POD. This patch moves kdump entry points to DIE_INIT_MONARCH_LEAVE and DIE_INIT_SLAVE_LEAVE. It also sets kdump_in_progress variable in the DIE_INIT_MONARCH_PROCESS event to not dump all active stack traces to the console in the case of kdump. I have tested this patch on an SN machine and a HP RX2600. Signed-off-by: Jay Lan <jlan@sgi.com> Acked-by: Zou Nan hai <nanhai.zou@intel.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
