The arm26 version of this had become horribly out of date. this is a sideways-port of the arm32 version, dropping the unwanted stuff and adjusted for arm26 compatability. Signed-off-by:

This diff effects a restructuring of arm26s directory layout. A number of files can now move to more logical locations, since there are no machine specific directories anymore. Signed-off-by:

This pulls in the execve changes made in arm32. Also, drops some old arm32 power management stuff thats no longer relevant in process.c. Signed-off-by:

This removes some unneeded definitions and makes the naming used within the file more consistent. Also adds some macros to make it easier to see how the interrupt handler is structured. The assembled output is identical to the original. Signed-off-by:

- Updates to makefiles required by the other changes in this patchset. - Also add some entries to the linker scripts. The linker scripts really ought to be merged into one script but that will have to wait. - Add a comment for building xipImages Update the compiler flags used to build arm26 so gcc 3.4 doesnt barf.

Add x86_64 support for Jack Steiner's SLIT sysfs patch Make Jack's code compile on x86-64 and add x86-64 low level support to save the SLIT pointer and a node_distance() implementation. Requires the previous SRAT patch. Signed-off-by:

Add SLIT (inter node distance) information to sysfs. [This is Jack's patch that he submitted on l-k. I'm submitting it for him because I need it for my x86-64 followon SLIT patch. Hope I don't stomp onto his toes with that one. If you already merged it please ignore] From: Jack Steiner Here is an update patch to externalize the SLIT information. I think I have encorporated all the comments that were posted previously) For example: # cd /sys/devices/system # find . ./node ./node/node5 ./node/node5/distance ./node/node5/numastat ./node/node5/meminfo ./node/node5/cpumap # cat ./node/node0/distance 10 20 64 42 42 22 # cat node/*/distance 10 20 64 42 42 22 20 10 42 22 64 84 64 42 10 20 22 42 42 22 20 10 42 62 42 64 22 42 10 20 22 84 42 62 20 10 Signed-off-by:Jack Steiner <steiner@sgi.com> Signed-off-by:

Allow to configure more CPUs and nodes. With clustered mode and AMD's big flat APIC mode there is no reason anymore to limit the max number of CPUs to 8. Increase the limit to 256 for now, which is the current APIC limit. Untested for now. Also increase the max number of nodes to 64. Remove the MAXNODE define and replace it with MAX_NUMNODES everywhere or the constant if the hardware limits the number of nodes. Also remove some obsolete comments. Signed-off-by:

Scheduler support for AMD CMP AMD dual core looks like HT but isn't really. Hide it from the scheduler. This works around problems with the domain scheduler. Also probably gives slightly better scheduling and disables SMT nice which is harmful on dual core. We still display it like HT in /proc/cpuinfo. This is to make it appear the same to license managers so that they count dual cores only as a single physical CPU. Signed-off-by:

Add SRAT NUMA discovery to x86-64. Previously the NUMA nodes on Opteron systems were directly read from the hardware registers of the northbridge. This version also supports reading it from the more generic ACPI SRAT table. This allows to support NUMA on all kinds of systems and in general gives more flexibility, but needs a bit of BIOS support. This implementation was not done before because the SRAT specification had a bad license from Microsoft that didn't allow to implement it on other OS. Now that ACPI 3.0 is released and SRAT is part of it that isn't a concern anymore. One side effect of this is that holes not described in SRAT (e.g. usually the 640K DOS and 4GB PCI memory holes) will not included in the nodes and won't get mem_map entries allocated. This may have side effects for some drivers. Some support for handling dual core AMD CPUs is included. SLIT parsing is done in a later patch. Depends on earlier patches to split up the ACPI boot parsing and to add better CMP support on x86-64. Can be disabled with numa=noacpi Signed-off-by:

Split ACPI boot table parsing Split ACPI boot table parsing into two parts. First a acpi_boot_table_init() call that initializes the basic ACPI table parsing machinery and discovers the RSDP, and then another call to actually parse the various boot tables. This is needed for a followon patch that implements SRAT support, because nodes need to be set up before the other ACPI tables can be parsed. On x86-64 I moved the early initialization very early because that is needed for the SRAT parser. On i386 it should be a nop. Signed-off-by:

Handle NX correctly in pageattr Second attempt to try to fix an long standing NX bug in change_page_attr. Hopefully this version will be better. The kernel text mapping aliases part of the physical memory and needs its caching attributes changed too. But when doing this one has to be very careful to handle the NX bit correctly. A previous slightly different version of this broke the X server on some RH systems. I hope this version will be better, but if you have X server problems please revert this one. Signed-off-by:

Remove duplicated FAKE_STACK_FRAME macro. FAKE_STACK_FRAME macro is defined twice. The one that gets used is in arch/x86_64/kernel/entry.S, and is slightly different codewise, although should have the same end result (uses pushq rather than addq %rsp + movq and has the extra dwarf annotations).
