remove unnecessary cast, KNF

Avoid gcc warnings

elide conversion warning.

Use uint32_t for __asm to appease clang.

branches: 1.12.2;
Disable arm32 __asm for _byte_swap_u16_variable since gcc4.5 produces
decent code for it. Fixes PR/46898.

Use defined(_ARM_ARCH_[67])

Add BSWAP16 and BSWAP32 macros for use in assembly.

Use __builtin_constant_p so that we only emit asm when
the expression is not a constant.

branches: 1.8.18; 1.8.34; 1.8.40; 1.8.42;
Remove clause 3 and 4 from TNF licenses

Merge kernel changes in matt-armv6 to HEAD.

branches: 1.6.50; 1.6.74; 1.6.76; 1.6.78;
Move all the stuff that detects bswapxx(constant) into the MI sys/bswap.h
Put the minimum to define the required inline assembler or C into the MD files.
NB: there may be some fallout from this!

branches: 1.5.2;
inline -> __inline

Remove leading __ from __(const|inline|signed|volatile) -- it is obsolete.

branches: 1.3.2; 1.3.24;
Ensure that some integer constants are always unsigned.

branches: 1.2.2; 1.2.4; 1.2.6; 1.2.8;
* Rename "word" -> 16, and "long" -> 32, as suggested by Ben Harris.
* Replace __byte_swap_32_variable() with a C version from Richard
Earnshaw that generates nearly identical assembly (and it would be
exactly identical with the addition of another peephole to GCC ARM
back-end).

Byte-swapping optimizations, enabled if compiling with GCC:
* Byte-swap 16-bit and 32-bit constants at compile-time.
* Inline 16-bit and 32-bit variable byte-swaps. These take 3 and 4
insns, respectively, and inlining saves the minimum 6 cycle penalty
to call/return from the byte swap function.
