sparc32: dma_alloc_coherent must honour gfp flags

2014-10-31T14:05:06+00:00

[ Upstream commit d1105287aabe88dbb3af825140badaa05cf0442c ]

dma_zalloc_coherent() calls dma_alloc_coherent(__GFP_ZERO)
but the sparc32 implementations sbus_alloc_coherent() and
pci32_alloc_coherent() doesn't take the gfp flags into
account.

Tested on the SPARC32/LEON GRETH Ethernet driver which fails
due to dma_alloc_coherent(__GFP_ZERO) returns non zeroed
pages.

procfs: new helper - PDE_DATA(inode)

2013-04-09T18:13:32+00:00

The only part of proc_dir_entry the code outside of fs/proc
really cares about is PDE(inode)->data.  Provide a helper
for that; static inline for now, eventually will be moved
to fs/proc, along with the knowledge of struct proc_dir_entry
layout.

sparc32: support leon + sun in dma_make_coherent()

2012-05-28T06:52:54+00:00

No need for two implementations - we check the cpu model.

sparc32,leon: always support leon in ioport

2012-05-28T06:52:53+00:00

Unconditially define pci32_dma_ops as this is used
for leon.

sparc32: Convert mmu_* interfaces from btfixup to method ops.

2012-05-13T20:57:05+00:00

This set of changes displays one major danger of btfixup, interface
signatures are not always type checked fully.  As seen here the iounit
variant of the map_dma_area routine had an incorrect type for one of
it's arguments.

It turns out to be harmless in this case, but just imagine trying to
debug something involving this kind of problem.  No thanks.

sparc32: drop btfixup in pgtable_32.h

Only one function left using btfixup.

sparc32: Trivial removal of sun4c references in comments.

2012-05-12T07:35:45+00:00

I left some around, like the ones in the openprom headers, since
we need to think about which pieces of those datastructures and
code we can completely toss now.
