linux-toradex.git/arch/tile/lib/exports.c, branch v3.4.2

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: avoid exporting a symbol no longer used by gcc

2011-11-03T20:58:42+00:00

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.

arch/tile: export some additional module symbols

2011-03-01T21:21:12+00:00

This adds a grab bag of symbols that have been missing for
various modules.

arch/tile: use extended assembly to inline __mb_incoherent()

2011-03-01T21:20:54+00:00

This avoids having to maintain an additional separate assembly
file, and of course the inline is slightly more efficient as well.

arch/tile: Various cleanups.

2010-08-13T12:52:19+00:00

This change rolls up random cleanups not representing any actual bugs.

- Remove a stale CONFIG_ value from the default tile_defconfig
- Remove unused tns_atomic_xxx() family of methods from 
- Optimize get_order() using Tile's "clz" instruction
- Fix a bad hypervisor upcall name (not currently used in Linux anyway)
- Use __copy_in_user_inatomic() name for consistency, and export it
- Export some additional hypervisor driver I/O upcalls and some homecache calls
- Remove the obfuscating MEMCPY_TEST_WH64 support code
- Other stray comment cleanups, #if 0 removal, etc.

arch/tile: Miscellaneous cleanup changes.

2010-07-06T17:41:51+00:00

This commit is primarily changes caused by reviewing "sparse"
and "checkpatch" output on our sources, so is somewhat noisy, since
things like "printk() -> pr_err()" (or whatever) throughout the
codebase tend to get tedious to read.  Rather than trying to tease
apart precisely which things changed due to which type of code
review, this commit includes various cleanups in the code:

- sparse: Add declarations in headers for globals.
- sparse: Fix __user annotations.
- sparse: Using gfp_t consistently instead of int.
- sparse: removing functions not actually used.
- checkpatch: Clean up printk() warnings by using pr_info(), etc.;
  also avoid partial-line printks except in bootup code.
  - checkpatch: Use exposed structs rather than typedefs.
  - checkpatch: Change some C99 comments to C89 comments.

In addition, a couple of minor other changes are rolled in
to this commit:

- Add support for a "raise" instruction to cause SIGFPE, etc., to be raised.
- Remove some compat code that is unnecessary when we fully eliminate
  some of the deprecated syscalls from the generic syscall ABI.
- Update the tile_defconfig to reflect current config contents.

arch/tile: core support for Tilera 32-bit chips.

2010-06-04T21:11:18+00:00

This change is the core kernel support for TILEPro and TILE64 chips.
No driver support (except the console driver) is included yet.

This includes the relevant Linux headers in asm/; the low-level
low-level "Tile architecture" headers in arch/, which are
shared with the hypervisor, etc., and are build-system agnostic;
and the relevant hypervisor headers in hv/.
