[SPARC64]: Implement pci_resource_to_user()

2007-12-27T03:33:46+00:00

This makes libpciaccess able to mmap() resources of the
device properly.

[SPARC64]: Fix OOPS in dma_sync_*_for_device()

2007-12-20T09:29:45+00:00

I included these operations vector cases for situations
where we never need to do anything, the entries aren't
filled in by any implementation, so we OOPS trying to
invoke NULL pointer functions.

Really make them NOPs, to fix the bug.

[SPARC64]: Fix two kernel linear mapping setup bugs.

2007-12-13T14:13:38+00:00

This was caught and identified by Greg Onufer.

Since we setup the 256M/4M bitmap table after taking over the trap
table, it's possible for some 4M mapping to get loaded in the TLB
beforhand which later will be 256M mappings.

This can cause illegal TLB multiple-match conditions.  Fix this by
setting up the bitmap before we take over the trap table.

Next, __flush_tlb_all() was not doing anything on hypervisor
platforms.  Fix by adding sun4v_mmu_demap_all() and calling it.

[SPARC64]: Fix linkage of enormous kernels.

2007-10-31T22:30:56+00:00

This was found by make randconfig

If the kernel .text is very large, the .fixup section branches
are too far away to be relocated correctly.

Use "sethi %hi(label), reg; jmpl reg + %lo(label); %g0" sequence
instead of the branch to fix this.

There is another case in switch_to() involving a branch, which
is fixed similarly.

[SPARC64]: Fix BACKOFF_SPIN on non-SMP.

2007-10-27T07:23:22+00:00

It can't be just empty, it has to at least branch
back to 'label'.

Add a Kconfig entry which will toggle some sanity checks on the sg
entry and tables.

Change table chaining layout

2007-10-22T19:20:01+00:00

Change the page member of the scatterlist structure to be an unsigned
long, and encode more stuff in the lower bits:

- Bits 0 and 1 zero: this is a normal sg entry. Next sg entry is located
  at sg + 1.
- Bit 0 set: this is a chain entry, the next real entry is at ->page_link
  with the two low bits masked off.
- Bit 1 set: this is the final entry in the sg entry. sg_next() will return
  NULL when passed such an entry.

It's thus important that sg table users use the proper accessors to get
and set the page member.

ide: add CONFIG_IDE_ARCH_OBSOLETE_INIT

2007-10-19T22:32:32+00:00

Add CONFIG_IDE_ARCH_OBSOLETE_INIT to drivers/ide/Kconfig and use it instead
of defining IDE_ARCH_OBSOLETE_INIT in .
