- use-vm_read-write-exec-to-set-vm_page_prot.patch removed from -mm tree

[akpm]

The patch titled
     use VM_READ/WRITE/EXEC to set vm_page_prot
has been removed from the -mm tree.  Its filename was
     use-vm_read-write-exec-to-set-vm_page_prot.patch

This patch was dropped because an updated version will be merged

------------------------------------------------------
Subject: use VM_READ/WRITE/EXEC to set vm_page_prot
From: Coly Li <[EMAIL PROTECTED]>

When setup vm_page_prot, some code use 0x7 instead of (VM_READ|VM_WRITE|=
VM_EXEC).  It does works well, but it will be better if we use the
VM_READ/WRITE/EXEC MACRO :-)

This patch uses (VM_READ|VM_WRITE|VM_EXEC) to replace 0x7 in vm_page_prot=
setup.
