Currently we allocate 64k space on the user stack and use it the msgbuf for
sys_{msgrcv,msgsnd} for compat and the results are later copied in user [
by copy_in_user]. This patch introduces helper routines for
sys_{msgrcv,msgsnd} as below:do_msgsnd() : Accepts the mtype and user space ptr to the buffer along with
the msqid and msgflg.do_msgrcv() : Accepts a kernel space ptr to mtype and a userspace ptr to
the buffer. The mtype has to be copied back the user space msgbuf by the
caller.These changes avoid the need to allocate the msgsize on the userspace (
thus removing the size limt ) and the overhead of an extra copy_in_user().Signed-off-by: Suzuki K P

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.Let it rip!
