Ease the deployment of clkdev by providing a default asm/clkdev.h for use if the arch does not have an include/asm/clkdev.h. Due to limitations in Kbuild we manually add clkdev.h to all architectures that don't have one rather than having the header appear by default.

xtensa has a header (in its include/asm directory) that is a thin wrapper around asm-generic/rmap.h. This wrapper is useless, since that header doesn't exist. It is also unused (no file includes asm/rmap.h). openrisc generates a similar header at build time (using a generic-y entry in include/asm/Kbuild). This generated header is useless and unused too. Remove this header and this generic-y entry. Signed-off-by: NPaul Bolle <pebolle@tiscali.nl> Signed-off-by: NMichal Marek <mmarek@suse.cz>

frv and xtensa both have a header (in their include/asm directories) that are thin wrappers around asm-generic/cpumask.h. These wrappers are useless, since that header doesn't exist. They are also unused (all files including asm/cpumask.h are x86 specific). hexagon and openrisc generate similar headers at build time (using a generic-y entry in include/asm/Kbuild). These generated headers are useless and unused too. Remove these headers and generic-y entries.

This changes the interfaces in <asm/word-at-a-time.h> to be a bit more complicated, but a lot more generic. In particular, it allows us to really do the operations efficiently on both little-endian and big-endian machines, pretty much regardless of machine details. For example, if you can rely on a fast population count instruction on your architecture, this will allow you to make your optimized <asm/word-at-a-time.h> file with that. NOTE! The "generic" version in include/asm-generic/word-at-a-time.h is not truly generic, it actually only works on big-endian. Why? Because on little-endian the generic algorithms are wasteful, since you can inevitably do better. The x86 implementation is an example of that. (The only truly non-generic part of the asm-generic implementation is the "find_zero()" function, and you could make a little-endian version of it. And if the Kbuild infrastructure allowed us to pick a particular header file, that would be lovely) The <asm/word-at-a-time.h> functions are as follows: - WORD_AT_A_TIME_CONSTANTS: specific constants that the algorithm uses. - has_zero(): take a word, and determine if it has a zero byte in it. It gets the word, the pointer to the constant pool, and a pointer to an intermediate "data" field it can set. This is the "quick-and-dirty" zero tester: it's what is run inside the hot loops. - "prep_zero_mask()": take the word, the data that has_zero() produced, and the constant pool, and generate an *exact* mask of which byte had the first zero. This is run directly *outside* the loop, and allows the "has_zero()" function to answer the "is there a zero byte" question without necessarily getting exactly *which* byte is the first one to contain a zero. If you do multiple byte lookups concurrently (eg "hash_name()", which looks for both NUL and '/' bytes), after you've done the prep_zero_mask() phase, the result of those can be or'ed together to get the "either or" case. - The result from "prep_zero_mask()" can then be fed into "find_zero()" (to find the byte offset of the first byte that was zero) or into "zero_bytemask()" (to find the bytemask of the bytes preceding the zero byte). The existence of zero_bytemask() is optional, and is not necessary for the normal string routines. But dentry name hashing needs it, so if you enable DENTRY_WORD_AT_A_TIME you need to expose it. This changes the generic strncpy_from_user() function and the dentry hashing functions to use these modified word-at-a-time interfaces. This gets us back to the optimized state of the x86 strncpy that we lost in the previous commit when moving over to the generic version. Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

elf.h: We can export some of these symbols to userspace. libc needs them and we just as well provide them as asm/elf.h as copying them into separate libc headers. ptrace.h: Having padding in the user_regs_struct isn't of any particular value and just confuses GDB. spr_defs isn't needed in userspace; libc has its own copy anyway.

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.
