2007-02-17[ARM] 4186/1: iop: remove cp6_enable/disable routinesDan Williams
This functionality is replaced by cp6_trap Signed-off-by: Dan Williams <dan.j.williams@intel.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-02-17[ARM] 4185/2: entry: introduce get_irqnr_preamble and arch_ret_to_userDan Williams
get_irqnr_preamble allows machines to take some action before entering the get_irqnr_and_base loop. On iop we enable cp6 access. arch_ret_to_user is added to the userspace return path to allow individual architectures to take actions, like disabling coprocessor access, before the final return to userspace. Per Nicolas Pitre's note, there is no need to cp_wait on the return to user as the latency to return is sufficient.

2007-02-14[ARM] 4184/1: iop: cp6 access handler (undef_hook)Dan Williams
Enable svc access to cp6 via an undefined instruction hook. Do not enable access for usr code. This patch also makes iop13xx select PLAT_IOP, this requires a small change to drivers/i2c/busses/i2c-iop3xx.c. Per Lennert Buytenhek's note, the cp6 trap routine is moved to arch/arm/plat-iop Per Nicolas Pitre's note, the cp_wait is skipped since the latency to return to the faulting function is longer than cp_wait.

2007-02-14[ARM] 4183/1: do_undefinstr: read svc undefined instructions with svc privilegesDan Williams
do_undefinstr currently does not expect undefined instructions in kernel code, since it always uses get_user() to read the instruction. Dereference the 'pc' pointer directly in the SVC case. Per Nicolas Pitre's note, kernel code is never in thumb mode. Signed-off-by: Dan Williams <dan.j.williams@intel.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-02-14[ARM] 4182/1: iop3xx: fix the ioremap implementation to not remap static rangesDan Williams
Implement a custom ioremap implementation for iop3xx. This saves establishing new mappings. It also cleans up the PCI IO resource to be a physical address rather than a virtual address as Russell pointed out on the original iop13xx port.

2007-02-06[ARM] Move processor_modes[] to .../process.cRussell King
bad_mode() currently prints the mode which caused the exception, and then causes an oops dump to be printed which again displays this information (since the CPSR in the struct pt_regs is correct.) This leads to processor_modes[] being shared between traps.c and process.c with a local declaration of it. We can clean this up by moving processor_modes[] to process.c and removing the duplication, resulting in processor_modes[] becoming static. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2007-02-03[PATCH] kexec: Avoid migration of already disabled irqs (ia64)Magnus Damm
This patch fixes up ia64 kexec support for HP rx2620 hardware. It does this by skipping migration of already disabled irqs. This is most likely a problem on other ia64 platforms as well, but I've only been able to reproduce it on one machine so far. The full story is that handle_bad_irq() gets invoked before starting the new kernel without this patch. This seems to happen when fixup_irqs() calls generic_handle_irq() on already migrated (and disabled) irqs. So by avoiding migration of disabled irqs we stay away of handle_bad_irq(). The code has been tested on three different ia64 machines, all with good results. It is possible to trigger the same bug by offlining a processor using echo 0 > /sys/devices/system/cpu/cpuX/online.

2007-02-02Revert "[PATCH] fix typo in geode_configre()@cyrix.c"Linus Torvalds
This reverts commit e4f0ae0ea63caceff37a13f281a72652b7ea71ba. It's not wrong, but it's not right either, and everybody seems to agree that the right fix is probably to do the ccr3 write after the ccr4 one (and that we also should clean it up a bit). And after that we need to really validate that all the bits that we write to ccr4 actually do work. The old 2.6.19 code was insane, and basically didn't change ccr4 at all (even though it certainly looks like it was the *intent* to do so). So let's revert the change that may fix things, just because it's not what was actually ever tested when the code was written, even if it _was_ the intent. There's a discussion on http://lkml.org/lkml/2007/1/9/63 that was started by the patch that now gets reverted, and that discussion may well contain the proper long-term fix.

2007-02-01[PATCH] __crc_... is intended to be absoluteAl Viro
i386 boot/compressed/relocs checks for absolute symbols and warns about unexpected ones. If you build with modversions, you get ~2500 warnings about __crc_<symbol>. These suckers are really absolute symbols - we do _not_ want to modify them on relocation. They are generated by genksyms - EXPORT_... generates a weak alias, then genksyms produces an ld script with __crc_<symbol> = <checksum> and it's fed to ld to produce the final object file. Their only use is to match kernel and module at modprobe time; they _must_ be absolute. boot/compressed/relocs has a whitelist of known absolute symbols, but it doesn't know about __crc_... stuff. As the result, we get shitloads of false positives on any ld(1) version. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2007-01-30[PATCH] i386: In assign_irq_vector look at all vectors before giving upEric W. Biederman
When the world was a simple and static place setting up irqs was easy. It sufficed to allocate a linux irq number and a find a free cpu vector we could receive that linux irq on. In those days it was a safe assumption that any allocated vector was actually in use so after one global pass through all of the vectors we would have none left. These days things are much more dynamic with interrupt controllers (in the form of MSI or MSI-X) appearing on plug in cards and linux irqs appearing and disappearing. As these irqs come and go vectors are allocated and freed, invalidating the ancient assumption that all allocated vectors stayed in use forever. So this patch modifies the vector allocator to walk through every possible vector before giving up, and to check to see if a vector is in use before assigning it. With these changes we stop leaking freed vectors and it becomes possible to allocate and free irq vectors all day long. This changed was modeled after the vector allocator on x86_64 where this limitation has already been removed. In essence we don't update the static variables that hold the position of the last vector we allocated until have successfully allocated another vector. This allows us to detect if we have completed one complete scan through all of the possible vectors. Acked-by: Auke Kok <auke-jan.h.kok@intel.com> Signed-off-by: Eric W.

2007-01-26[SPARC64]: Set g4/g5 properly in sun4v dtlb-prot handling.David S. Miller
Mirror the logic in the sun4u handler, we have to update both registers even when we branch out to window fault fixup handling. The way it works is that if we are in etrap processing a fault already, g4/g5 holds the original fault information. If we take a window spill fault while doing etrap, then we put the window spill fault info into g4/g5 and this is what the top-level fault handler ends up processing first. Then we retry the originally faulting instruction, and process the original fault at that time. This is all necessary because of how constrained the trap registers are in these code paths. These cases trigger very rarely, so even if there is some performance implication it's doesn't happen very often. In fact the rarity is why it took so long to trigger and find this particular bug.

2007-01-26Fix Maple PATA IRQ assignment.David Woodhouse
On the Maple board, the AMD8111 IDE is in legacy mode... except that it appears on IRQ 20 instead of IRQ 15. For drivers/ide this was handled by the architecture's "pci_get_legacy_ide_irq()" function, but in libata we just hard-code the numbers 14 and 15. This patch provides asm-powerpc/libata-portmap.h which maps the IRQ as appropriate, having added a pci_dev argument to the ATA_{PRIM,SECOND}ARY_IRQ macros. There's probably a better way to do this -- especially if we observe that the _only_ case in which this seemingly-generic "pci_get_legacy_ide_irq()" function returns anything other than 14 and 15 for primary and secondary respectively is the case of the AMD8111 on the Maple board -- couldn't we handle that with a special case in the pata_amd driver, or perhaps with a PCI quirk for Maple to switch it into native mode during early boot and assign resources properly?

This patch fixes core dumps to include the vDSO vma, which is left out now. It removes the special-case core writing macros, which were not doing the right thing for the vDSO vma anyway. Instead, it uses VM_ALWAYSDUMP in the vma; there is no need for the fixmap page to be installed. It handles the CONFIG_COMPAT_VDSO case by making elf_core_dump use the fake vma from get_gate_vma after real vmas in the same way the /proc/PID/maps code does. This changes core dumps so they no longer include the non-PT_LOAD phdrs from the vDSO. I made the change to add them in the first place, but in turned out that nothing ever wanted them there since the advent of NT_AUXV. It's cleaner to leave them out, and just let the phdrs inside the vDSO image speak for themselves.

2007-01-26[PATCH] Fix CONFIG_COMPAT_VDSORoland McGrath
I wouldn't mind if CONFIG_COMPAT_VDSO went away entirely. But if it's there, it should work properly. Currently it's quite haphazard: both real vma and fixmap are mapped, both are put in the two different AT_* slots, sysenter returns to the vma address rather than the fixmap address, and core dumps yet are another story. This patch makes CONFIG_COMPAT_VDSO disable the real vma and use the fixmap area consistently. This makes it actually compatible with what the old vdso implementation did.

2007-01-25[ARM] 4111/1: Allow VFP to work with thread migration on SMPCatalin Marinas
The current lazy saving of the VFP registers is no longer possible with thread migration on SMP. This patch implements a per-CPU vfp-state pointer and the saving of the VFP registers at every context switch. The registers restoring is still performed in a lazy way.
