There are two bugs: - the 'error page' is forgot to be released [ it is unneeded after commit a2766325, for backport, we still do kvm_release_pfn_clean for the error pfn ] - guest pages are always released regardless of the unmapped page (e,g, caused by hwpoison) Signed-off-by: Xiao Guangrong <xiaoguangrong@linux.vnet.ibm.com> Signed-off-by: Avi Kivity <avi@redhat.com>

Two reasons: - x86 can integrate rmap and rmap_pde and remove heuristics in __gfn_to_rmap(). - Some architectures do not need rmap. Since rmap is one of the most memory consuming stuff in KVM, ppc'd better restrict the allocation to Book3S HV.

Pull VFS fixes and cleanups from Al Viro. Most of this is the series to remove sync_supers() and the ->write_supers VFS callback from Artem Bityutskiy. One commit to do the actual removal work, a whole series of commits to fix up stale comments etc all over the tree. There's also a regression fix for an incorrect use of mnt_drop_write() in do_dentry_open(). * 'for-linus-2' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: missed mnt_drop_write() in do_dentry_open() UBIFS: nuke pdflush from comments gfs2: nuke pdflush from comments drbd: nuke pdflush from comments nilfs2: nuke write_super from comments hfs: nuke write_super from comments vfs: nuke pdflush from comments jbd/jbd2: nuke write_super from comments btrfs: nuke pdflush from comments btrfs: nuke write_super from comments ext4: nuke pdflush from comments ext4: nuke write_super from comments ext3: nuke write_super from comments Documentation: fix the VM knobs descritpion WRT pdflush Documentation: get rid of write_super vfs: kill write_super and sync_supers

Finally we can kill the 'sync_supers' kernel thread along with the '->write_super()' superblock operation because all the users are gone. Now every file-system is supposed to self-manage own superblock and its dirty state. The nice thing about killing this thread is that it improves power management. Indeed, 'sync_supers' is a source of monotonic system wake-ups - it woke up every 5 seconds no matter what - even if there were no dirty superblocks and even if there were no file-systems using this service (e.g., btrfs and journalled ext4 do not need it). So it was wasting power most of the time. And because the thread was in the core of the kernel, all systems had to have it. So I am quite happy to make it go away. Interestingly, this thread is a left-over from the pdflush kernel thread which was a self-forking kernel thread responsible for all the write-back in old Linux kernels. It was turned into per-block device BDI threads, and 'sync_supers' was a left-over. Thus, R.I.P, pdflush as well.
