Fix pread() and pwrite() syscall on ARM EABI (Kirill Shutemov).
pread() and pwrite() have differences in arguments between ARM EABI and OABI. See arch/arm/kernel/entry-common.S in Linux kernel source for additional information. Signed-off-by: Kirill A. Shutemov <kirill@shutemov.name> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5272 c046a42c-6fe2-441c-8c8c-71466251a162
