* | [PATCH] genirq: rename desc->handler to desc->chipIngo Molnar2006-06-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

UNPROFILE_OBJS mustn't be listed in USER_OBJS but are compiled as such. I've also verified that unprofile didn't work in the current form, because we set _c_flags directly (using CFLAGS and not USER_CFLAGS, which is wrong), which is normally used by c_flags, but we also override c_flags for all USER_OBJS, and there we don't call unprofile. Instead it only worked for unmap.o, the only one which wasn't a USER_OBJ. We need to set c_flags (which is not a public Kbuild API) to clear a lot of compilation flags like -nostdinc which Kbuild forces on everything. *) Rather than $(CFLAGS_$(notdir $@)), which expands to CFLAGS_anObj.s when building "anObj.s", use $(CFLAGS_$(*F).o) which always accesses CFLAGS_anObj.o, like done by Kbuild. *) Make c_flags apply to all targets having the same basename, rather than listing .s, .i, .lst and .o, with the use (which I tested) of $(USER_OBJS:.o=.%): c_flags = ... and of - $(obj)/unmap.c: _c_flags = ... + $(obj)/unmap.%: _c_flags = ...

| | | | | | | | | | Clean up the jmpbuf code. Since softints, we no longer use sig_setjmp, so the UML_SIGSETJMP wrapper now has a misleading name. Also, I forgot to change the buffers from sigjmp_buf to jmp_buf.

* [PATCH] uml: MADV_REMOVE fixesJeff Dike2006-04-19
| | | | | | | | | | | | | MADV_REMOVE fixes - change the test mapping to be MAP_SHARED instead of MAP_PRIVATE, as MADV_REMOVE on MAP_PRIVATE maps won't work. Also, use the kernel's definition of MADV_REMOVE instead of hardcoding it if there isn't a libc definition.

* [PATCH] uml: make 64-bit COW files compatible with 32-bit onesPaolo 'Blaisorblade' Giarrusso2006-04-19
| | | | | | | | | | | | | | This is the minimal fix to make 64-bit UML binaries create 32-bit compatible COW files and read them. I've indeed tested that current code doesn't do this - the code gets SIGFPE for a division by a value read at the wrong place, where 0 is found.

* [PATCH] uml: avoid warnings for diffent names for an unsigned quadwordPaolo 'Blaisorblade' Giarrusso2006-04-11
| | | | | | | | | | | | | | Since on some 64-bit systems __u64 is rightfully defined to unsigned long and GCC recognizes anyway unsigned long and unsigned long long as different, fix some types back to being unsigned long long to avoid warnings and errors (for prototype mismatch) on those systems.

* [PATCH] uml: local_irq_save, not local_save_flagsPaolo 'Blaisorblade' Giarrusso2006-04-11
| | | | | | | | | | | The call to local_save_flags seems bogus since it is followed by local_irq_restore, and it's intended to lock the list from concurrent mconsole_interrupt invocations.

* [PATCH] uml: fix big stack userPaolo 'Blaisorblade' Giarrusso2006-04-11
| | | | | | | | | | | | | | | | Switch this proc from storing 4k of data (a whole path) on the stack to keeping it on the heap. Maybe it's not called in process context but only in early boot context (where in UML you have a normal process stack on the host) but just to be safe, fix it. While at it some little readability simplifications.

* [PATCH] uml: fix failure path after conversionPaolo 'Blaisorblade' Giarrusso2006-04-11
| | | | | | | | | | | | | | | Little fix for error paths in this code. - Some bug come from conversion to os-Linux (open() doesn't follow the kernel -errno return convention, while the old code called os_open_file() which followed it). This caused the wrong return code to be printed. - Then be more precise about what happened and do some whitespace fixes.
