2007-12-08[IA64] SGI Altix : fix bug in sn_io_late_init()Mike Habeck1-6/+5
When initializing pci_controller->node to point to the closest node we need to take into consideration that a PIC PCI Bridge ASIC can be connected to a headless/memless node just like the TIOCP and TIOCE Bridge ASICs Signed-off-by: Mike Habeck <habeck@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

2007-12-08[IA64] export copy_page() to modulesAndrew Morton3-3/+6
With the unionfs patch applied I get ERROR: "copy_page" [fs/unionfs/unionfs.ko] undefined! the other architectures (some, at least) export copy_page() so I guess ia64 should also do so. To do this we need to move the copy_page() functions out of lib.a and into built-in.o and add the EXPORT_SYMBOL().

2007-12-07[AVR32] Fix wrong pt_regs in critical exception handlerHaavard Skinnemoen1-2/+2
It's not like it really matters at this point since the system is dying anyway, but handle_critical pushes too few registers on the stack so the register dump, which makes the register dump look a bit strange. This patch fixes it. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
2007-12-07[AVR32] Fix copy_to_user_page() breakageHaavard Skinnemoen1-10/+10
The current implementation of copy_to_user_page() gives "vaddr" to the cache instruction when trying to sync the icache with the dcache. If vaddr does not exist in the TLB, the CPU will silently abort the operation, which may result in the caches staying out of sync. To fix this, pass the "dst" parameter to flush_icache_range() instead -- we know this is valid because we just wrote to it. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
2007-12-07[AVR32] Follow the rules when dealing with the OCD systemHaavard Skinnemoen4-227/+323
The current debug trap handling code does a number of things that are illegal according to the AVR32 Architecture manual. Most importantly, it may try to schedule from Debug Mode, thus clearing the D bit, which can lead to "undefined behaviour". It seems like this works in most cases, but several people have observed somewhat unstable behaviour when debugging programs, including soft lockups. So there's definitely something which is not right with the existing code. The new code will never schedule from Debug mode, it will always exit Debug mode with a "retd" instruction, and if something not running in Debug mode needs to do something debug-related (like doing a single step), it will enter debug mode through a "breakpoint" instruction. The monitor code will then return directly to user space, bypassing its own saved registers if necessary (since we don't actually care about the trapped context, only the one that came before.) This adds three instructions to the common exception handling code, including one branch. It does not touch super-hot paths like the TLB miss handler.

2007-12-07[AVR32] Clean up OCD register usageHaavard Skinnemoen5-33/+35
Generate a new set of OCD register definitions in asm/ocd.h and rename __mfdr() and __mtdr() to ocd_read() and ocd_write() respectively. The bitfield definitions are a lot more complete now, and they are entirely based on bit numbers, not masks. This is because OCD registers are frequently accessed from assembly code, where bit numbers are a lot more useful (can be fed directly to sbr, bfins, etc.) Bitfields that consist of more than one bit have two definitions: _START, which indicates the number of the first bit, and _SIZE, which indicates the number of bits. These directly correspond to the parameters taken by the bfextu, bfexts and bfins instructions. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>

The cleanup 09cadedbdc01f1a4bea1f427d4fb4642eaa19da9 broke the oprofile configuration for MIPS by allowing oprofile support to be built for kernel models where oprofile doesn't have a chance in hell to work. Just a dependecy list on a number of architectures is - surprise - broken and should as per past discussions probably in most considered to be broken in most cases.

2007-12-06[POWERPC] Fix hardware IRQ time accounting problem.Tony Breeds1-1/+1
The commit fa13a5a1f25f671d084d8884be96fc48d9b68275 (sched: restore deterministic CPU accounting on powerpc), unconditionally calls update_process_tick() in system context. In the deterministic accounting case this is the correct thing to do. However, in the non-deterministic accounting case we need to not do this, since doing this results in the time accounted as hardware irq time being artificially elevated. Also this collapses 2 consecutive '#ifdef CONFIG_VIRT_CPU_ACCOUNTING' checks in time.h into one for neatness.
