asm-generic: use asm-generic/unaligned.h for most architectures

2021-05-10T15:43:15Z

There are several architectures that just duplicate the contents of asm-generic/unaligned.h, so change those over to use the file directly, to make future modifications easier. The exceptions are: - arm32 sets HAVE_EFFICIENT_UNALIGNED_ACCESS, but wants the unaligned-struct version - ppc64le disables HAVE_EFFICIENT_UNALIGNED_ACCESS but includes the access-ok version - most m68k also uses the access-ok version without setting HAVE_EFFICIENT_UNALIGNED_ACCESS. - sh4a has a custom inline asm version - openrisc is the only one using the memmove version that generally leads to worse code.

xtensa: move headers files to arch/xtensa/include

2008-11-06T18:25:09Z

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.
