Andrew Morton 1aaf18ff9d [PATCH] check_user_page_readable() deadlock fix ... Fix bug identifued by Richard Purdie <rpurdie@rpsys.net>. oprofile calls check_user_page_readable() from interrupt context, so we deadlock over various VFS locks. But check_user_page_readable() doesn't imply either a read or a write of the page's contents. Change __follow_page() so that check_user_page_readable() can tell __follow_page() that we're not accessing the page's contents, and use that info to avoid the troublesome lock-takings. Also, make follow_page() inline for the single callsite in memory.c to save a bit of stack space.
