[-- Attachment #1: clone64-change-clone_flag-type-to-u64.patch --]
[-- Type: text/plain, Size: 38093 bytes --]
From: Cedric Le Goater <clg@fr.ibm.com>
This is a preliminary patch changing the clone_flags type to 64bits
for all the routines called by do_fork().
It prepares ground for the next patch which introduces an enhanced
version of clone() supporting 64bits flags.
This is work in progress. All conversions might not be done yet.

From: clg @ 2008-02-11 9:58 UTC (permalink / raw)
To: akpm; +Cc: linux-kernel, xemul, serue, Cedric Le Goater
[-- Attachment #1: clone64-syscall.patch --]
[-- Type: text/plain, Size: 14216 bytes --]
From: Cedric Le Goater <clg@fr.ibm.com>
This patch adds 2 new syscalls :
long sys_clone64(unsigned long flags_high, unsigned long flags_low,
unsigned long newsp);
long sys_unshare64(unsigned long flags_high, unsigned long flags_low);
The current version of clone64() does not support CLONE_PARENT_SETTID and
CLONE_CHILD_CLEARTID because we would exceed the 6 registers limit of some
arches. It's possible to get around this limitation but we might not
need it as we already have clone()
Signed-off-by: Cedric Le Goater <clg@fr.ibm.com>
