2005-09-10kbuild: fix generic asm-offsets.h supportSam Ravnborg
iThis fixes a bug where the generated asm-offsets.h file was saved in the source tree even with make O=. Thanks to Stephen Rothwell <sfr@canb.auug.org.au> for the report. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2005-09-10kbuild: add objectifySam Ravnborg
Use foo := $(call objectify, $(foo)) to prefix $(foo) with $(obj)/ unless $(foo) is an absolute path. For now no in-tree users - soon to come. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2005-09-10[PATCH] uml: avoid already done dirtyingPaolo 'Blaisorblade' Giarrusso
The PTE returned from handle_mm_fault is already marked as dirty and accessed if needed. Also, since this is not set with set_pte() (which sets NEWPAGE and NEWPROT as needed), this wouldn't work anyway. This version has been updated and fixed, thanks to some feedback from Jeff Dike.

2005-09-10[PATCH] uml: fix fault handler on writePaolo 'Blaisorblade' Giarrusso
The UML fault handler was recently changed to enforce PROT_NONE protections, by requiring VM_READ or VM_EXEC on VMA's. However, by mistake, things were changed such that VM_READ is always checked, also on write faults; so a VMA mapped with only PROT_WRITE is not readable (unless it's prefaulted with MAP_POPULATE or with a write), which is different from i386. Discovered while testing remap_file_pages protection support. Signed-off-by: Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-09-10[PATCH] uml: inline mk_pte and various friendsPaolo 'Blaisorblade' Giarrusso
Turns out that, for UML, a *lot* of VM-related trivial functions are not inlined but rather normal functions. In other sections of UML code, this is justified by having files which interact with the host and cannot therefore include kernel headers, but in this case there's no such justification. I've had to turn many of them to macros because of missing declarations. While doing this, I've decided to reuse some already existing macros.

2005-09-10[PATCH] x86_64 linker script cleanups for debug sectionsPaolo 'Blaisorblade' Giarrusso
Use the new macros for x86_64 too. Note that the current scripts includes different definitions; more exactly, it only contains part of the DWARF2 sections and the .comment one from Stabs. Shouldn't be a problem, anyway. Cc: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-09-10[PATCH] i386 / uml: add dwarf sections to static link scriptPaolo 'Blaisorblade' Giarrusso
Inside the linker script, insert the code for DWARF debug info sections. This may help GDB'ing a Uml binary. Actually, it seems that ld is able to guess what I added correctly, but normal linker scripts include this section so it should be correct anyway adding it. On request by Sam Ravnborg <sam@ravnborg.org>, I've added it to asm-generic/vmlinux.lds.s. I've also moved there the stabs debug section, used the new macro in i386 linker script and added DWARF debug section to that. In the truth, I've not been able to verify the difference in GDB behaviour after this change (I've seen large improvements with another patch). This may depend on my binutils version, older one may have worse defaults. However, this section is present in normal linker script, so add it at least for the sake of cleanness.

2005-09-10[PATCH] ppc32: support hotplug cpu on powermacsPaul Mackerras
This allows cpus to be off-lined on 32-bit SMP powermacs. When a cpu is off-lined, it is put into sleep mode with interrupts disabled. It can be on-lined again by asserting its soft-reset pin, which is connected to a GPIO pin. With this I can off-line the second cpu in my dual G4 powermac, which means that I can then suspend the machine (the suspend/resume code refuses to suspend if more than one cpu is online, and making it cope with multiple cpus is surprisingly messy).

2005-09-10[PATCH] ppc32: Kill init on unhandled synchronous signalsPaul Mackerras
This is a patch that I have had in my tree for ages. If init causes an exception that raises a signal, such as a SIGSEGV, SIGILL or SIGFPE, and it hasn't registered a handler for it, we don't deliver the signal, since init doesn't get any signals that it doesn't have a handler for. But that means that we just return to userland and generate the same exception again immediately. With this patch we print a message and kill init in this situation. This is very useful when you have a bug in the kernel that means that init doesn't get as far as executing its first instruction. :) Without this patch the system hangs when it gets to starting the userland init; with it you at least get a message giving you a clue about what has gone wrong.
