arch: syscalls: add missing FORCE and fix 'targets' to make if_changed work

The rules in these Makefiles cannot detect the command line change
because the prerequisite 'FORCE' is missing.

Adding 'FORCE' will result in the headers being rebuilt every time
because the 'targets' additions are also wrong; the file paths in
'targets' must be relative to the current Makefile.

Fix all of them so the if_changed rules work correctly.

"Nothing too big or scary in here:

- Support mremap() for the VDSO, primarily to allow CRIU to restore
the VDSO to its checkpointed location.

- Restore the MIPS32 cBPF JIT, after having reverted the enablement
of the eBPF JIT for MIPS32 systems in the 5.5 cycle.

- Improve cop0 counter synchronization behaviour whilst onlining CPUs
by running with interrupts disabled.

- Better match FPU behaviour when emulating multiply-accumulate
instructions on pre-r6 systems that implement IEEE754-2008 style
MACs.

- Loongson64 kernels now build using the MIPS64r2 ISA, allowing them
to take advantage of instructions introduced by r2.

- Support for the Ingenic X1000 SoC & the really nice little CU Neo
development board that's using it.

- Support for WMAC on GARDENA Smart Gateway devices.

- Lots of cleanup & refactoring of SGI IP27 (Origin 2*) support in
preparation for introducing IP35 (Origin 3*) support.

Merge tag 'mips_4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux

Pull MIPS updates from Paul Burton:
"Here's the main MIPS pull for Linux 4.21. Core architecture changes
include:

- Syscall tables & definitions for unistd.h are now generated by
scripts, providing greater consistency with other architectures &
making it easier to add new syscalls.

- Support for building kernels with no floating point support, upon
which any userland attempting to use floating point instructions
will receive a SIGILL. Mostly useful to shrink the kernel & as
preparation for nanoMIPS support which does not yet include FP.

- MIPS SIMD Architecture (MSA) vector register context is now exposed
by ptrace via a new NT_MIPS_MSA regset.

- ASIDs are now stored as 64b values even for MIPS32 kernels,
expanding the ASID version field sufficiently that we don't need to
worry about overflow & avoiding rare issues with reused ASIDs that
have been observed in the wild.

- The branch delay slot "emulation" page is now mapped without write
permission for the user, preventing its use as a nice location for
attacks to execute malicious code from.

- Support for ioremap_prot(), primarily to allow gdb or other ptrace
users the ability to view their tracee's memory using the same
cache coherency attribute.

- Optimizations to more cpu_has_* macros, allowing more to be
compile-time constant where possible.

- Enable building the whole kernel with UBSAN instrumentation.

- Enable building the kernel with link-time dead code & data
elimination.

Platform specific changes include:

- The Boston board gains a workaround for DMA prefetching issues with
the EG20T Platform Controller Hub that it uses.

- Cleanups to Cavium Octeon code removing about 20k lines of
redundant code, mostly unused or duplicate register definitions in
headers.

- defconfig updates for the DECstation machines, including new
defconfigs for r4k & 64b machines.

- Further work on Loongson 3 support.

- DMA fixes for SiByte machines"

mips: add system call table generation support

mips: add system call table generation support

The system call tables are in different format in all
architecture and it will be difficult to manually add,
modify or delete the syscall table entries in the res-
pective files. To make it easy by keeping a script and
which will generate the uapi header and syscall table
file. This change will also help to unify the implemen-
tation across all architectures.

The system call table generation script is added in
kernel/syscalls directory which contain the scripts to
generate both uapi header file and system call table
files. The syscall.tbl will be input for the scripts.

syscall.tbl contains the list of available system calls
along with system call number and corresponding entry
point. Add a new system call in this architecture will
be possible by adding new entry in the syscall.tbl file.

Adding a new table entry consisting of:
- System call number.
- ABI.
- System call name.
- Entry point name.
- Compat entry name, if required.

syscallhdr.sh, syscallnr.sh and syscalltbl.sh will gene-
rate uapi header unistd_n64/n32/o32.h, unistd_nr_n64/n32/-
o32.h and syscall_table_32_o32/64_n64/64-n32/64-o32.h files
respectively. All *.sh files will parse the content sys-
call.tbl to generate the header and table files. unistd-
_n64/n32/o32.h and unistd_nr_n64/n32/o32.h will be included
by uapi/asm/unistd.h and syscall_table_32_o32/64_n64/64-n32-
/64-o32.h is included by kernel/syscall_table32_o32/64-
_n64/64-n32/64-o32.S - the real system call table.

ARM, s390 and x86 architecuture does have similar support.
I leverage their implementation to come up with a generic
solution.
