return has just been\nthat r0 holds the return value, and an error is only signalled like it is\nfor kernel code, with a negative small number.\n\nHowever, this means that in multiple places in userspace we end up writing\nthe same three-cycle idiom that tests for a small negative number for\nerror. It seems cleaner to instead move that code into the kernel, and\nset r1 to hold zero on success or errno on failure; previously, r1 was\njust zeroed on return from the kernel (to avoid leaking kernel state).\nThis way a single conditional branch after the syscall is sufficient\nto test for the failure case. The number of cycles taken is the same,\nbut the error-checking code is in just one place, so total code size is\nsmaller, and random userspace syscall code is easier to understand.\n\nSigned-off-by: Chris Metcalf \u003ccmetcalf@tilera.com\u003e\n" }, { "commit": "c745a8a11fa1df6078bfc61fc29492ed43f71c2b", "tree": "2db1cdf9cd0d0e892f4f92de1fd2700ac319f04a", "parents": [ "1fcbe027b5d29ec9cd0eeb753c14fb366ae852ac" ], "author": { "name": "Chris Metcalf", "email": "cmetcalf@tilera.com", "time": "Fri Aug 13 08:52:19 2010 -0400" }, "committer": { "name": "Chris Metcalf", "email": "cmetcalf@tilera.com", "time": "Fri Aug 13 08:52:19 2010 -0400" }, "message": "arch/tile: Various cleanups.\n\nThis change rolls up random cleanups not representing any actual bugs.\n\n- Remove a stale CONFIG_ value from the default tile_defconfig\n- Remove unused tns_atomic_xxx() family of methods from \u003casm/atomic.h\u003e\n- Optimize get_order() using Tile\u0027s \"clz\" instruction\n- Fix a bad hypervisor upcall name (not currently used in Linux anyway)\n- Use __copy_in_user_inatomic() name for consistency, and export it\n- Export some additional hypervisor driver I/O upcalls and some homecache calls\n- Remove the obfuscating MEMCPY_TEST_WH64 support code\n- Other stray comment cleanups, #if 0 removal, etc.\n\nSigned-off-by: Chris Metcalf \u003ccmetcalf@tilera.com\u003e\n" }, { "commit": "1fcbe027b5d29ec9cd0eeb753c14fb366ae852ac", "tree": "b0d80646567ac71238cf2ffb33e29ad33d758816", "parents": [ "32020effaf713c0c669864301bcd5dac6b9bb9e0" ], "author": { "name": "Chris Metcalf", "email": "cmetcalf@tilera.com", "time": "Fri Aug 13 08:40:57 2010 -0400" }, "committer": { "name": "Chris Metcalf", "email": "cmetcalf@tilera.com", "time": "Fri Aug 13 08:40:57 2010 -0400" }, "message": "arch/tile: support backtracing on TILE-Gx\n\nThis functionality was stubbed out until recently.

So we\ncan unify dma_get_cache_alignment implementations.\n\nNote that some architectures implement dma_get_cache_alignment wrongly.\ndma_get_cache_alignment() should return the minimum DMA alignment. So\nfully-coherent architectures should return 1.
