xtensa: reorganize SR referencing2012-10-16T04:48:08ZMax Filippovjcmvbkbc@gmail.com2012-10-14T23:55:38Zurn:sha1:bc5378fcba974317f9657c4fdc78af227e1e1068
- reference SRs by names where possible, not by numbers;
- get rid of __stringify around SR names where possible;
- remove unneeded SR names from asm/regs.h;
- add SREG_ prefix to remaining SR names;

xtensa: Fix FLUSH_DCACHE macro for some variants.2010-05-02T05:55:21ZChris Zankelchris@zankel.net2010-05-02T05:55:21Zurn:sha1:91e080633221cadece6c1c37786ef8a18a9d1a5e
Define ARCH_IMPLEMENTS_FLUSH_DCACHE_PAGE also for processor configurations
that don't have cache-aliasing.

block: add helpers to run flush_dcache_page() against a bio and a request's pages2009-11-26T08:16:19ZIlya Loginovisloginov@gmail.com2009-11-26T08:16:19Zurn:sha1:2d4dc890b5c8fabd818a8586607e6843c4375e62
Mtdblock driver doesn't call flush_dcache_page for pages in request. So,
this causes problems on architectures where the icache doesn't fill from
the dcache or with dcache aliases. The patch fixes this.
The ARCH_IMPLEMENTS_FLUSH_DCACHE_PAGE symbol was introduced to avoid
pointless empty cache-thrashing loops on architectures for which
flush_dcache_page() is a no-op. Every architecture was provided with this
flush pages on architectires where ARCH_IMPLEMENTS_FLUSH_DCACHE_PAGE is
equal 1 or do nothing otherwise.
See "fix mtd_blkdevs problem with caches on some architectures" discussion
on LKML for more information.

xtensa: cache inquiry and unaligned cache handling functions2009-06-22T09:36:50ZOskar Schirmeros@emlix.com2009-06-10T19:58:45Zurn:sha1:bd974240c9a7c6c560504bf390cd8985a16b68f6
The existing xtensa cache handling functions work on page-aligned
memory regions.
These functions are needed for the s6000 dma engine which can work on
a byte-granularity.

xtensa: move headers files to arch/xtensa/include2008-11-06T18:25:09ZChris Zankelchris@zankel.net2008-11-06T14:40:46Zurn:sha1:367b8112fe2ea5c39a7bb4d263dcdd9b612fae18
Move all header files for xtensa to arch/xtensa/include and platform and
variant header files to the appropriate arch/xtensa/platforms/ and
arch/xtensa/variants/ directories.
Moving the files gets also rid of all uses of symlinks in the Makefile.
This has been completed already for the majority of the architectures
and xtensa is one out of six missing.
