Regularly, when a new header is created in include/uapi/, the developer
forgets to add it in the corresponding Kbuild file. This error is usually
detected after the release is out.
In fact, all headers under uapi directories should be exported, thus it's
useless to have an exhaustive list.
After this patch, the following files, which were not exported, are now
exported (with make headers_install_all):
asm-arc/kvm_para.h
asm-arc/ucontext.h
asm-blackfin/shmparam.h
asm-blackfin/ucontext.h

Note that I have removed from this list the files which are generated in every
exported directories (like .install or .install.cmd).
Thanks to Julien Floret <julien.floret@6wind.com> for the tip to get all
subdirs with a pure makefile command.
For the record, note that exported files for asm directories are a mix of
files listed by:
- include/uapi/asm-generic/Kbuild.asm;
- arch/<arch>/include/uapi/asm/Kbuild;
- arch/<arch>/include/asm/Kbuild.

KGDB fails to build after f51e2f191112 ("ARC: make sure instruction_pointer()
returns unsigned value")
The hack to force one specific reg to unsigned backfired. There's no
reason to keep the regs signed after all.

Commit 97bc386fc12d "ARC: Add guard macro to uapi/asm/unistd.h"
inhibited multiple inclusion of ARCH unistd.h. This however hosed the system
since Generic syscall table generator relies on it being included twice,
and in lack-of an empty table was emitted by C preprocessor.
Fix that by allowing one exception to rule for the special case (just
like Xtensa)

Chen originally proposed this as "right thing to do" however I
actually ran into this when building perf tools. Some of the utils
include unistd.h as well as linux/unistd.h. Since -I includes kernel
headers too, we end up including the ARC unistd.h twice, leading to
redefinition nwarnings.

Historically, pt_regs have had orig_r8, an overloaded container for
(1) backup copy of r8 (syscall number Trap Exceptions)
(2) additional system state: (syscall/Exception/Interrupt)
There is no point in keeping (1) since syscall number is never clobbered
in-place, in pt_regs, unlike r0 which duals as first syscall arg as well
as syscall return value and in case of syscall restart, the orig arg0
needs restoring (from orig_r0) after having been updated in-place with
syscall ret value.
This further paves way to convert (2) to contain ECR itself (rather than
current madeup values)

This is trickier than prev two:
* context switching code saves kernel mode callee regs in the format of
struct callee_regs thus needs adjustment. This also reduces the height
of topmost kernel stack frame by 1 word.
* Since kernel stack unwinder is sensitive to height of topmost kernel
stack frame, that needs a word of adjustment too.
ptrace needs a bit of updating since pt_regs now diverges from
user_regs_struct.

1. ./genfilelist.pl arch/arc/include/asm/
2. Create arch/arc/include/uapi/asm/Kbuild as follows
+# UAPI Header export list
+include include/uapi/asm-generic/Kbuild.asm
3. ./disintegrate-one.pl arch/arc/include/{,uapi/}asm/<above-list>
4. Edit arch/arc/include/asm/Kbuild to remove ref to
asm-generic/Kbuild.asm
- To work around empty uapi/asm/setup.h added a placholder comment.
- Also a manual #ifdef __ASSEMBLY__ for a late ptrace change
