alpha: Add export.h for THIS_MODULE/EXPORT_SYMBOL

2011-10-31T23:31:03+00:00

These files were getting it via the implicit module.h
presence that was everywhere.

alpha: remove dma64_addr_t usage

2010-10-28T01:03:17+00:00

dma_addr_t is always 64 bit on alpha. So let's use dma_addr_t instead.

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h

2010-03-30T13:02:32+00:00

percpu.h is included by sched.h and module.h and thus ends up being
included when building most .c files.  percpu.h includes slab.h which
in turn includes gfp.h making everything defined by the two files
universally available and complicating inclusion dependencies.

percpu.h -> slab.h dependency is about to be removed.  Prepare for
this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability.  As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.

  http://userweb.kernel.org/~tj/misc/slabh-sweep.py

The script does the followings.

* Scan files for gfp and slab usages and update includes such that
  only the necessary includes are there.  ie. if only gfp is used,
  gfp.h, if slab is used, slab.h.

* When the script inserts a new include, it looks at the include
  blocks and try to put the new include such that its order conforms
  to its surrounding.  It's put in the include block which contains
  core kernel includes, in the same order that the rest are ordered -
  alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
  doesn't seem to be any matching order.

* If the script can't find a place to put a new include (mostly
  because the file doesn't have fitting include block), it prints out
  an error message indicating which .h file needs to be added to the
  file.

The conversion was done in the following steps.

1. The initial automatic conversion of all .c files updated slightly
   over 4000 files, deleting around 700 includes and adding ~480 gfp.h
   and ~3000 slab.h inclusions.  The script emitted errors for ~400
   files.

2. Each error was manually checked.  Some didn't need the inclusion,
   some needed manual addition while adding it to implementation .h or
   embedding .c file was more appropriate for others.  This step added
   inclusions to around 150 files.

3. The script was run again and the output was compared to the edits
   from #2 to make sure no file was left behind.

4. Several build tests were done and a couple of problems were fixed.
   e.g. lib/decompress_*.c used malloc/free() wrappers around slab
   APIs requiring slab.h to be added manually.

5. The script was run on all .h files but without automatically
   editing them as sprinkling gfp.h and slab.h inclusions around .h
   files could easily lead to inclusion dependency hell.  Most gfp.h
   inclusion directives were ignored as stuff from gfp.h was usually
   wildly available and often used in preprocessor macros.  Each
   slab.h inclusion directive was examined and added manually as
   necessary.

6. percpu.h was updated not to include slab.h.

7. Build test were done on the following configurations and failures
   were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my
   distributed build env didn't work with gcov compiles) and a few
   more options had to be turned off depending on archs to make things
   build (like ipr on powerpc/64 which failed due to missing writeq).

   * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
   * powerpc and powerpc64 SMP allmodconfig
   * sparc and sparc64 SMP allmodconfig
   * ia64 SMP allmodconfig
   * s390 SMP allmodconfig
   * alpha SMP allmodconfig
   * um on x86_64 SMP allmodconfig

8. percpu.h modifications were reverted so that it could be applied as
   a separate patch and serve as bisection point.

Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.

dma-mapping: alpha: use include/linux/pci-dma-compat.h

2010-03-12T23:52:42+00:00

This converts Alpha to use include/linux/pci-dma-compat.h.  Alpha is the
only architecutre that implements the PCI DMA API in the own way.  That
makes it difficult to implement the generic DMA API via the PCI bus
specific DMA API.

The generic DMA API calls the PCI DMA API implementation in
arch/alpha/kernel/pci_iommu.c on non Jensen systems.  It calls the DMA API
in arch/alpha/kernel/pci-noop.c on Jensen systems.

alpha: AGP update (fixes compile failure)

2009-09-24T14:21:06+00:00

This brings Alpha AGP platforms in sync with the change to struct
agp_memory (unsigned long *memory => struct page **pages).

Only compile tested (I don't have titan/marvel hardware), but this change
looks pretty straightforward, so hopefully it's ok.

alpha: convert u64 to unsigned long long

2009-04-01T15:59:16+00:00

Convert alpha architecture to use u64 as unsigned long long.  This is
being done so that (a) all arches use u64 as unsigned long long and (b)
printk of a u64 as %ll[ux] will not generate format warnings by gcc.

The only gcc cross-compiler that I have is 4.0.2, which generates errors
about miscompiling __weak references, so I have commented out that line in
compiler-gcc4.h so that most of these compile, but more builds and real
machine testing would be Real Good.

alpha: remove remaining FUNCTION occurrences

2008-04-28T15:58:27+00:00

__FUNCTION__ is gcc-specific, use __func__

The change in pci-iommu,c should be safe as arena has not been assigned
when we get to this point.

Some were within #if 0 blocks, have changed them and left the blocks
as they appear to be debugging infrastructure.

A #define FN __FUNCTION__ was removed and occurances of FN were replaced
with __func__ as well.
