Make a global linux/const.h header file instead of having multiple,
per-arch files, and convert current users of asm/const.h to use
linux/const.h.
Built on x86_64 and sparc64.

This patch is based on Rusty's recent cleanup of the EFLAGS-related
macros; it extends the same kind of cleanup to control registers and
MSRs.
It also unifies these between i386 and x86-64; at least with regards
to MSRs, the two had definitely gotten out of sync.

This patch makes pgtable.h and page.h safe to include
in assembly files like head.S. Allowing us to use
symbolic constants instead of hard coded numbers when
refering to the page tables.
This patch copies asm-sparc64/const.h to asm-x86_64 to
get a definition of _AC() a very convinient macro that
allows us to force the type when we are compiling the
code in C and to drop all of the type information when
we are using the constant in assembly. Previously this
was done with multiple definition of the same constant.
const.h was modified slightly so that it works when given
CONFIG options as arguments.
This patch adds #ifndef __ASSEMBLY__ ... #endif
and _AC(1,UL) where appropriate so the assembler won't
choke on the header files. Otherwise nothing
should have changed.
AK: added const.h to exported headers to fix headers_check

Make the contents of the userspace asm/setup.h header consistent on all
architectures:
- export setup.h to userspace on all architectures
- export only COMMAND_LINE_SIZE to userspace
- frv: move COMMAND_LINE_SIZE from param.h
- i386: remove duplicate COMMAND_LINE_SIZE from param.h
- arm:
- export ATAGs to userspace
- change u8/u16/u32 to __u8/__u16/__u32

The use of SEGMENT_RPL_MASK in the i386 ptrace.h introduced by
x86-allow-a-kernel-to-not-be-in-ring-0.patch broke the UML build, as UML
includes the underlying architecture's ptrace.h, but has no easy access to the
x86 segment definitions.
Rather than kludging around this, as in the past, this patch splits the
userspace-usable parts, which are the bits that UML needs, of ptrace.h into
ptrace-abi.h, which is included back into ptrace.h. Thus, there is no net
effect on i386.
As a side-effect, this creates a ptrace header which is close to being usable
in /usr/include.
x86_64 is also treated in this way for consistency. There was some trailing
whitespace there, which is cleaned up.
