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

2011-12-03T20:31:49Z

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. Signed-off-by: Chris Metcalf

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

2011-12-03T20:31:47Z

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. Signed-off-by: Chris Metcalf

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

2011-12-03T20:31:41Z

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. Signed-off-by: Chris Metcalf

arch/tile: factor out header

2011-11-03T20:58:54Z

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

2011-11-03T20:58:48Z

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. Signed-off-by: Chris Metcalf

arch/tile: avoid exporting a symbol no longer used by gcc

2011-11-03T20:58:42Z

An earlier Tilera compiler generated calls to an "__ll_mul" function for long long multiplication. Our libgcc supported that as an alias for the normal __muldi3 routine, so we made it available to kernel modules as well. However, for a while now the compiler has internally been generating only the standard __muldi3 symbol, and the version we are giving back to the community does not have the __ll_mul alias, so we are removing it from the kernel too.

is used by glibc's from , which means that it can't clutter the namespace with random symbols or #defines. However, we use to get a suitable type to hold a machine register. This change makes safe to use in this kind of context if __need_int_reg_t is defined prior to including the file; in that case, it only defines a few symbols that are safe in the ISO namespace (prefixed with double underscores). then uses the __uint_reg_t type instead of the normal uint_reg_t.

tile: revert change from to in asm files

The 32-bit TILEPro support uses some #defines in for atomic support routines in assembly. To make this more explicit, I've turned those includes into includes of , which should hopefully make it clear that they shouldn't be bombed into in any cleanups. Signed-off-by: Chris Metcalf
