mm: pagefault_disabled()

2012-02-15T16:32:32+00:00

Wrap the test for pagefault_disabled() into a helper, this allows us
to remove the need for current->pagefault_disabled on !-rt kernels.

mm: Fixup all fault handlers to check current->pagefault_disable

2012-02-15T16:32:32+00:00

Necessary for decoupling pagefault disable from preempt count.

arch/tile: use new generic {enable,disable}_percpu_irq() routines

2011-12-03T20:31:49+00:00

We provided very similar routines internally, but now we can hook
into the generic framework by supplying our routines as function
pointers in the irq_chip structure instead.

arch/tile: fix double-free bug in homecache_free_pages()

2011-12-03T20:31:47+00:00

When freeing the page with this API, the page was "put" twice.
This was only discovered bringing up an MPT fusion controller, which
actually used the API; it hadn't been invoked previously, so the bug
had gone unnoticed.

arch/tile: add a few #includes and an EXPORT to catch up with kernel changes.

2011-12-03T20:31:41+00:00

The empty_zero_page[] export is required for ZERO_PAGE() module references.
The #includes are due to changes in implicit inclusion, and should of
course have been in the sources from the beginning.

arch/tile: factor out header

2011-11-03T20:58:54+00:00

The kernel code was using some  headers that included a mix
of hardware-specific information (typically found in Tilera 
headers) and structures, enums, and function declarations supporting
the disassembly function of the tile-desc.c sources.

This change refactors that code so that a hardware-specific, but
OS- and application-agnostic header, is created: .
This header is then exported to userspace along with the other
 headers and can be used to build userspace code; in particular,
it is used by glibc as part of implementing the backtrace() function.

The new header, together with a header that specifically describes
the disassembly code ( with _32 and _64 variants),
replaces the old  and 
headers.

As part of this change, we are also renaming the 32-bit constants
from TILE_xxx to TILEPRO_xxx to better reflect the fact that they
are specific to the TILEPro architecture, and not to TILE-Gx
and any successor "tile" architecture chips.

arch/tile: add the headers to the set of installed kernel headers

2011-11-03T20:58:48+00:00

These headers are similar to the  headers that describe kernel
APIs, but instead describe aspects of the actual hardware in an
OS- and application-independent manner.  We need to include them in
the set of installed headers so that userspace tools (including glibc)
can build purely from the provided kernel headers.
