[PATCH] SPARC64: Set g4/g5 properly in sun4v dtlb-prot handling.

2007-02-05T16:31:42Z

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.

[PATCH] SPARC64: Handle ISA devices with no 'regs' property.

2007-01-10T19:05:21Z

And this points out that the return value from isa_dev_get_resource() and the 'pregs' arg to isa_dev_get_irq() are totally unused. Based upon a patch from Richard Mortimer Signed-off-by: David S. Miller Signed-off-by: Chris Wright

[PATCH] SPARC64: Fix "mem=xxx" handling.

2007-01-10T19:05:21Z

We were not being careful enough. When we trim the physical memory areas, we have to make sure we don't remove the kernel image or initial ramdisk image ranges. Signed-off-by: David S. Miller Signed-off-by: Chris Wright

[SPARC]: Fix robust futex syscalls and wire up migrate_pages.

2006-11-06T00:51:03Z

When I added the entries for the robust futex syscall entries, I forgot to bump NR_SYSCALLS. The current situation is error-prone because NR_SYSCALLS lives in entry.S where the system call limit checks are enforced. Move the definition to asm/unistd.h in order to make this mistake much more difficult to make. And wire up sys_migrate_pages since the powerpc folks implemented the compat wrapper for us.

[SPARC64]: Fix Tomatillo/Schizo IRQ handling.

2006-10-31T03:33:33Z

The code in schizo_irq_trans_init() should set irq_data->sync_reg to the location of the SYNC register if this is Tomatillo, and set it to zero otherwise. But that is not what it is doing. As a result, non-Tomatillo systems were trying to access a non-existent register resulting in bus errors at the first PCI interrupt. Thanks to Roland Stigge for the bug report.

[PATCH] vmlinux.lds: consolidate initcall sections

2006-10-27T22:34:51Z

Add a vmlinux.lds.h helper macro for defining the eight-level initcall table, teach all the architectures to use it. This is a prerequisite for a patch which performs initcall synchronisation for multithreaded-probing.

[SPARC]: Fix bus_id[] string overflow.

2006-10-27T08:03:31Z

dp->path_component_name can be larger than ->bus_id[] so use a different naming scheme for this stuff. Noticed by Jurij Smakov. Signed-off-by: David S. Miller

[SPARC64]: Fix memory corruption in pci_4u_free_consistent().

2006-10-26T05:39:16Z

The second argument to free_npages() was being incorrectly calculated, which would thus access far past the end of the arena->map[] bitmap. Signed-off-by: David S. Miller
