This patch implements the setxattr, getxattr, and removexattr syscalls
if CONFIG_ATTR is enabled.
Note that since libattr uses indirect syscalls for these, this change
depends on the fix for indirect syscall handling on MIPS.

On MIPS, some syscall arguments are taken from the stack. This patch adds
verification such that do_syscall() is only invoked if all arguments
have been successfully taken from the stack.

Change the number of argument for MIPS sys_syscall from 0 to 8. This
allows arguments for indirect syscalls to be processed correctly.

These patches implement the setxattr, getxattr, and removexattr syscalls.
Since libattr uses indirect syscalls for these, the fix for the indirect
syscall handling on MIPS is needed for these to work.

don't know if this may cause breakage when the arguments are not actually
there? If someone can confirm that this is harmless, the simple approach is
probably better? Thanks.
