Subject: move-die-notifier-handling-to-common-code: fix vmalloc_sync_all()
From: Andrew Morton <[EMAIL PROTECTED]>
Christoph removed the vmalloc_sync_all() calls from i386 and x86_64's
register_die_notifier(). Apparently we need them.
Put them back by making vmalloc_sync_all() a vmalloc API functions and play
tricks with attribute(weak) for architectures which do not implement it.
