* [MIPS] IP22: Fix hang due to messing with timer interrupt handlerThomas Bogendoerfer2007-10-17

* [MIPS] Probe for usability of cp0 compare interrupt.Ralf Baechle2007-10-17
| | | | | | | | | Some processors offer the option of using the interrupt on which normally the count / compare interrupt would be signaled as a normal interupt pin. Previously this required some ugly hackery for each system which is much easier done by a quick and simple probe. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
* [MIPS] SYNC emulation for MIPS I processorsMaciej W. Rozycki2007-10-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Userland, including the C library and the dynamic linker, is keen to use the SYNC instruction, even for "generic" MIPS I binaries these days. Which makes it less than useful on MIPS I processors. This change adds the emulation, but as our do_ri() infrastructure was not really prepared to take yet another instruction, I have rewritten it and its callees slightly as follows. Now there is only a single place a possible signal is thrown from. The place is at the end of do_ri(). The instruction word is fetched in do_ri() and passed down to handlers. The handlers are called in sequence and return a result that lets the caller decide upon further processing. If the result is positive, then the handler has picked the instruction, but a signal should be thrown and the result is the signal number. If the result is zero, then the handler has successfully simulated the instruction. If the result is negative, then the handler did not handle the instruction; to make it more obvious the calls do not follow the usual 0/-Exxx result convention they now return -1 instead of -EFAULT. The calculation of the return EPC is now at the beginning. The reason is it is easier to handle it there as emulation callees may modify a register and an instruction may be located in delay slot of a branch whose result depends on the register. It has to be undone if a signal is to be raised, but it is not a problem as this is the slow-path case, and both actions are done in single places now rather than the former being scattered through emulation handlers. The part of do_cpu() being covered follows the changes to do_ri(). Signed-off-by: Maciej W. Rozycki <macro@linux-mips.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org> ---

| * | | [POWERPC] Add 1TB workaround for PA6TOlof Johansson2007-10-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PA6T has a bug where the slbie instruction does not honor the large segment bit. As a result, we have to always use slbia when switching context. We don't have to worry about changing the slbie's during fault processing, since they should never be replacing one VSID with another using the same ESID. I.e. there's no risk for inserting duplicate entries due to a failed slbie of the old entry. So as long as we clear it out on context switch we should be fine.

It turns out SLAB has a 2 second per cpu timer that causes this. After switching to SLUB I see some nice 4 second sleeps which is the limit on this POWER6 box (the decrementer ticks at 512MHz): slept 4.19 sec slept 4.19 sec slept 4.19 sec slept 4.19 sec slept 3.96 sec slept 3.80 sec slept 2.99 sec Since SLUB is now the default and some powerpc defconfigs already enable it, lets enable SLUB across the board for consistency. While doing this I also noticed that the maple defconfig has SLAB debugging enabled which is sure to make your box nice and slow. Fix that too.

There are no plans to do anything about this piece of code and it does not fit anywhere anymore, so it is not just a matter of maintenance or the lack of. There are still some bits that might be added to the new lkkbd.c driver based on the old code, and the embedded hardware documentation which is otherwise quite hard to get hold of might be useful to keep too.

* | | remove include/asm-*/ipc.hAdrian Bunk2007-10-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All asm/ipc.h files do only #include <asm-generic/ipc.h>. This patch therefore removes all include/asm-*/ipc.h files and moves the contents of include/asm-generic/ipc.h to include/linux/ipc.h.

* | | add-vmcore: add a prefix "VMCOREINFO_" to the vmcoreinfo macrosKen'ichi Ohmichi2007-10-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a prefix "VMCOREINFO_" to the vmcoreinfo macros. Old vmcoreinfo macros were defined as generic names SYMBOL/SIZE/OFFSET /LENGTH/CONFIG, and it is impossible to grep for them. So these names should be changed.

It creates a small dumpfile by filtering unnecessary pages for the analysis. To distinguish unnecessary pages, it needs a vmlinux file including the debugging information. These days, the debugging package becomes a huge file, and it is hard to install it into each system. To solve the problem, kdump developers discussed it at lkml and kexec-ml. As the result, we reached the conclusion that necessary information for dump filtering (called "vmcoreinfo") should be embedded into the first kernel file and it should be accessed through /proc/vmcore during the second kernel. (http://www.uwsg.iu.edu/hypermail/linux/kernel/0707.0/1806.html) Dan Aloni created the patch set for the above implementation. (http://www.uwsg.iu.edu/hypermail/linux/kernel/0707.1/1053.html) And I updated it for multi architectures and memory models.
