powerpc: Remove ioremap_flags

2011-05-19T04:30:43+00:00

We have a confusing number of ioremap functions. Make things just a
bit simpler by merging ioremap_flags and ioremap_prot.

powerpc: Add ioremap_wc

2011-05-19T04:30:42+00:00

Add ioremap_wc so drivers can request write combining on kernel
mappings.

powerpc/pci: Split IO vs MMIO indirect access hooks

2011-04-27T04:18:27+00:00

The goal is to avoid adding overhead to MMIO when only PIO is needed

powerpc: Wire up /proc/vmallocinfo to our ioremap()

2009-03-11T06:10:14+00:00

This adds the necessary bits and pieces to powerpc implementation of
ioremap to benefit from caller tracking in /proc/vmallocinfo, at least
for ioremap's done after mem init as the older ones aren't tracked.

powerpc: Remove dead BIO_VMERGE_BOUNDARY definition

2008-12-16T04:53:19+00:00

The block layer dropped the virtual merge feature
(b8b3e16cfe6435d961f6aaebcfd52a1ff2a988c5).  BIO_VMERGE_BOUNDARY
definition is meaningless now (For POWER, BIO_VMERGE_BOUNDARY has been
meaningless for a long time since POWER disables the virtual merge
feature).

POWERPC: Allow 32-bit hashed pgtable code to support 36-bit physical

2008-09-24T21:29:44+00:00

This rearranges a bit of code, and adds support for
36-bit physical addressing for configs that use a
hashed page table.  The 36b physical support is not
enabled by default on any config - it must be
explicitly enabled via the config system.

This patch *only* expands the page table code to accomodate
large physical addresses on 32-bit systems and enables the
PHYS_64BIT config option for 86xx.  It does *not*
allow you to boot a board with more than about 3.5GB of
RAM - for that, SWIOTLB support is also required (and
coming soon).

powerpc: Move include files to arch/powerpc/include/asm

2008-08-04T02:02:00+00:00

from include/asm-powerpc.  This is the result of a

mkdir arch/powerpc/include/asm
git mv include/asm-powerpc/* arch/powerpc/include/asm

Followed by a few documentation/comment fixups and a couple of places
where  was being used explicitly.  Of the latter only
one was outside the arch code and it is a driver only built for powerpc.
