* xtensa: fix build error in xtensa/include/asm/io.hPaul Gortmaker2012-04-231-0/+1
| | | | | | | | | | | Caused by commit 6c03438edeb5c359af35f060ea016ca65671c269 kernel.h: doesn't explicitly use bug.h, so don't include it. This header uses bug.h so explicitly include it now that the implicit presence was removed by 6c03438ed. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

* xtensa: move headers files to arch/xtensa/includeChris Zankel2008-11-061-0/+200
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.
