[Qemu-devel] [PULL 7/9] linux-user: Fix certain argument alignment cases for Mips64

[Leon Alrae <leon.alrae@imgtec.com>]

From: Aleksandar Markovic <aleksandar.markovic@imgtec.com>

The function that is changed in this patch is supposed to indicate that
there was certain argument rearrangement related to 64-bit arguments on
32-bit platforms. The background on such rearrangements can be found,
for example, in the man page for syscall(2).

However, for 64-bit Mips architectures there is no such rearrangement,
and this patch reflects it.
