* [IA64] increase .data.patch offsetAndrew Morton2007-12-07

| * [AVR32] Fix wrong pt_regs in critical exception handlerHaavard Skinnemoen2007-12-07
| | | | | | | | | | | | | | | | | | 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>
| * [AVR32] Fix copy_to_user_page() breakageHaavard Skinnemoen2007-12-07
| | | | | | | | | | | | | | | | | | | | | | | | 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>
| * [AVR32] Follow the rules when dealing with the OCD systemHaavard Skinnemoen2007-12-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * [AVR32] Clean up OCD register usageHaavard Skinnemoen2007-12-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| * [POWERPC] Fix hardware IRQ time accounting problem.Tony Breeds2007-12-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
