2006-06-29[PATCH] genirq MSI fixesIngo Molnar
This is a fixed up and cleaned up replacement for genirq-msi-fixes.patch, which should solve the i386 4KSTACKS problem. I also added Ben's idea of pushing the __do_IRQ() check into generic_handle_irq(). I booted this with MSI enabled, but i only have MSI devices, not MSI-X devices. I'd still expect MSI-X to work now. irqchip migration helper: call __do_IRQ() if a descriptor is attached to an irqtype-style controller. This also fixes MSI-X IRQ handling on i386 and x86_64.

2006-06-29[PATCH] genirq: rename desc->handler to desc->chipIngo Molnar
This patch-queue improves the generic IRQ layer to be truly generic, by adding various abstractions and features to it, without impacting existing functionality. While the queue can be best described as "fix and improve everything in the generic IRQ layer that we could think of", and thus it consists of many smaller features and lots of cleanups, the one feature that stands out most is the new 'irq chip' abstraction. The irq-chip abstraction is about describing and coding and IRQ controller driver by mapping its raw hardware capabilities [and quirks, if needed] in a straightforward way, without having to think about "IRQ flow" (level/edge/etc.) type of details. This stands in contrast with the current 'irq-type' model of genirq architectures, which 'mixes' raw hardware capabilities with 'flow' details. The patchset supports both types of irq controller designs at once, and converts i386 and x86_64 to the new irq-chip design. As a bonus side-effect of the irq-chip approach, chained interrupt controllers (master/slave PIC constructs, etc.) are now supported by design as well. The end result of this patchset intends to be simpler architecture-level code and more consolidation between architectures. We reused many bits of code and many concepts from Russell King's ARM IRQ layer, the merging of which was one of the motivations for this patchset. This patch: rename desc->handler to desc->chip. Originally i did not want to do this, because it's a big patch. But having both "desc->handler", "desc->handle_irq" and "action->handler" caused a large degree of confusion and made the code appear alot less clean than it truly is. I have also attempted a dual approach as well by introducing a desc->chip alias - but that just wasnt robust enough and broke frequently. So lets get over with this quickly. The conversion was done automatically via scripts and converts all the code in the kernel. This renaming patch is the first one amongst the patches, so that the remaining patches can stay flexible and can be merged and split up without having some big monolithic patch act as a merge barrier.

2006-06-29[S390] virtual cpu accounting vs. machine checks.Martin Schwidefsky
If a machine checks interrupts the external or the i/o interrupt handler before they have completed the cpu time calculations, the accounting goes wrong. After the cpu returned from the machine check handler to the interrupted interrupt handler, a negative cpu time delta can occur. If the accumulated cpu time in lowcore is small enough this value can get negative as well. The next jiffy interrupt will pick up that negative value, shift it by 12 and add the now huge positive value to the cpu time of the process. To solve this the machine check handler is modified not to change any of the timestamps in the lowcore if the machine check interrupted kernel context.

2006-06-29[S390] console_unblank woes.Martin Schwidefsky
The software watchdog calls machine_restart from a timer function. The s390 machine_restart calls console_unblank to flush the console output. This is needed for panic to get the panic message printed. If console_unblank is called in interrupt a BUG is triggered in acquire_console_sem. That makes the software watchdog panic instead of restarting the machine. To get around this problem the call to console_unblank is made conditionally on !in_interrupt() || oops_in_progress.

2006-06-28[ARM] nommu: remove fault-armv, mmap and mm-armv files from nommu buildRussell King
Remove fault-armv.o, mmap.o and mm-armv.o from uclinux builds - these are concerned with MMU-ful operations, and as such are redundant for uclinux. Since this also removes iotable_init() and iotable_init() is used extensively in the platform support files, just make it a no-op. Based upon a couple of patches by Hyok. Signed-off-by: Hyok S.

2006-06-28[ARM] Remove TABLE_SIZE, and several unused function prototypesRussell King
TABLE_SIZE is never used in arch/arm/mm/init.c. create_memmap_holes(), memtable_init, and setup_io_desc() no longer exist in the kernel. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-06-28[ARM] nommu: Provide a simple flush_dcache_page implementationRussell King
nommu doesn't require a complex flush_dcache_page implementation like the MMU-ful CPUs do, so provide a simplified version in nommu.c and omit flush.c from the build as appropriate. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
