ARM EABI: fix 64-bit syscall's arguments decoding
ARM OABI and ARM EABI have different function parameters passing rules.
With EABI, 64-bit function parameters passed in registers are aligned to
an even-numbered register instead of using the next available pair, see
http://lkml.org/lkml/2006/1/12/175
This rule also applies to syscall's arguments.
* linux/arm/syscallent.h (pread, pwrite, truncate64, ftruncate64,
readahead, preadv, pwritev): Fix number of arguments.
* util.c (printllval): Align 64bit argument to 64bit boundary on
__ARM_EABI__.
