Since commit fcc8487d47 ("uapi: export all headers under uapi
directories"), all (and only) headers under uapi directories are
exported, but asm-generic wrappers are still exceptions.
To complete de-coupling the uapi from kernel headers, move generic-y
of exported headers to uapi/asm/Kbuild.
With this change, "make headers_install" will just need to parse
uapi/asm/Kbuild to build up exported headers.
For arm64, "generic-y += kvm_para.h" is doubled in asm/Kbuild and
uapi/asm/Kbuild. So, the one in the former can be simply removed.

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.

arm64 defines its own ucontext structure which is incompatible with the
struct defined (and exposed to userspace by) the asm-generic headers.
glibc carries its own struct definition that is compatible with the
arm64 definition, but we should expose our format in the uapi headers in
case other libraries want to make use of the ucontext pushed as part of
an arm64 sigframe.
This patch moves the arm64 asm/ucontext.h to the uapi headers, along
with the necessary #include of linux/types.h.

This patch implements the functions required for the perf registers API,
allowing the perf tool to interface kernel register dumps with libunwind
in order to provide userspace backtracing.
Compat mode is also supported.
Only the general purpose user space registers are exported, i.e.:
PERF_REG_ARM_X0,
...
PERF_REG_ARM_X28,
PERF_REG_ARM_FP,
PERF_REG_ARM_LR,
PERF_REG_ARM_SP,
PERF_REG_ARM_PC
and not the PERF_REG_ARM_V* registers.
