The patch titled
remove kernel syscalls
has been added to the -mm tree. Its filename is
remove-kernel-syscalls.patch
See http://www.zip.com.au/~akpm/linux/patches/stuff/added-to-mm.txt to find
out what to do about this
------------------------------------------------------
Subject: remove kernel syscalls
From: Arnd Bergmann <arnd@xxxxxxxx>
The last thing we agreed on was to remove the macros entirely for 2.6.19,
on all architectures. Unfortunately, I think nobody actually _did_ that,
so they are still there.
Signed-off-by: Andrew Morton <akpm@xxxxxxxx>

- * suitable and optimal for both xt-xcc and gcc.
- *
- * Linux takes system-call arguments in registers. The following
- * design is optimized for user-land apps (e.g., glibc) which
- * typically have a function wrapper around the "syscall" assembly
- * instruction. It satisfies the Xtensa ABI while minizing argument
- * shifting.
- *
- * The Xtensa ABI and software conventions require the system-call
- * number in a2. If an argument exists in a2, we move it to the next
- * available register. Note that for improved efficiency, we do NOT
- * shift all parameters down one register to maintain the original
- * order.
- *
- * At best case (zero arguments), we just write the syscall number to
- * a2. At worst case (1 to 6 arguments), we move the argument in a2
- * to the next available register, then write the syscall number to
- * a2.
- *
- * For clarity, the following truth table enumerates all possibilities.
- *
- * arguments syscall number arg0, arg1, arg2, arg3, arg4, arg5
- * --------- -------------- ----------------------------------
- * 0 a2
- * 1 a2 a3
- * 2 a2 a4, a3
- * 3 a2 a5, a3, a4
- * 4 a2 a6, a3, a4, a5
- * 5 a2 a7, a3, a4, a5, a6
- * 6 a2 a8, a3, a4, a5, a6, a7
