By looking at the file arch/mips/kernel/scall32-o32.S in Linux
kernel, it can be deduced that, for Mips32 platform, syscall
corresponding to number _NR_fadvise64 as defined in kernel file
arch/mips/include/uapi/asm/unistd.h translates to kernel function
sys_fadvise64_64, and that argument layout for this system call is
as follows:
0 32 0 32
+----------------+----------------+
(arg1) | fd | __pad | (arg2)
+----------------+----------------+
(arg3) | buffer | (arg4)
+----------------+----------------+
(arg5) | len | (arg6)
+----------------+----------------+
(arg7) | advise | not used | (arg8)
+----------------+----------------+
The same argument layout can be deduced from glibc code, and
relevant commit messages in linux kernel and glibc.
The fix is to change TARGET_NR_fadvise64 to TARGET_NR_fadvise64_64
in Mips32 syscall numbers table. Array mips_syscall_args[] in
linux-user/main.c also already have "fadvise64_64" (and not
"fadvise64") in corresponding place for the syscall number in
question, so no change for linux-user/main.c.
This patch also fixes the failure LTP test posix_fadvise03, if
executed on Qemu-emulated Mips32 platform (user mode).

This change covers arm, aarch64, mips. Others to follow?
The change was prompted by QEMU warning about a syscall 384 (get_random())
with Debian armhf binaries (ARMv7).

All others updated except unicore, which doesn't look right to
begin with.

Add syscall numbers for new syscall numbers; this brings us
into line with Linux 2.6.39.2.
