Module Name:    src
Committed By:   dsl
Date:           Wed Nov 21 00:15:08 UTC 2007

Modified Files:
        src/sys/arch/i386/i386: copy.S

Log Message:
When copying system call arguments into kernel space, either copy 4
arguments (enough for the majority of calls) or the maximum of 10 (8 plus
2 for sys__syscall).
Avoids all the unlikely-to-be-predicted-correctly in the unrolled loop.
This might be a problem if a thread's stack doesn't have the extra args
mapped - but that is extremely unlikely.
