acpi_memhotplug.c: auto bind the memory device which is hotplugged before the driver is loaded

If the memory device is hotplugged before the driver is loaded, the user
cannot see this device under the directory /sys/bus/acpi/devices/, and the
user cannot bind it by hand after the driver is loaded.  This patch
introduces a new feature to bind such device when the driver is being
loaded.

acpi_memhotplug.c: bind the memory device when the driver is being loaded

We had introduced acpi_hotmem_initialized to avoid strange add_memory fail
message.  But the memory device may not be used by the kernel, and the
device should be bound when the driver is being loaded.  Remove
acpi_hotmem_initialized to allow that the device can be bound when the
driver is being loaded.

fs/block_dev.c: page cache wrongly left invalidated after revalidate_disk()

We found that bdev->bd_invalidated was left set once revalidate_disk() is
called, which results in page cache flush every time that device is open.

Specifically, we found this problem in MD block device.  Once we resize a
MD device, mdadm --monitor periodically flush all page cache for that
device every 60 or 1000 seconds when it opens the device.

This bug lies since at least 3.2.0 till the latest kernel(3.6.2).
Patch is attached.

The following steps will reproduce the problem.

1. prepair a block device(ex. /dev/sdb).
2. create two partitions.

sudo parted /dev/sdb
mklabel gpt
mkpart primary 0% 50%
mkpart primary 50% 100%

3. create a md device.

sudo mdadm -C /dev/md/hoge -l 1 -n 2 -e 1.2 --assume-clean --auto=md \
 --symlink=no /dev/sdb1 /dev/sdb2

4. create file system and mount it

sudo mkfs.ext3 /dev/md/hoge
sudo mkdir /mnt/test
sudo mount /dev/md/hoge /mnt/test

5. try to resize the device

sudo mdadm -G /dev/md/hoge --size=max

6. create a file to fill file cache.

sudo dd if=/dev/urandom of=/mnt/test/data bs=1M count=10
and verity the current status of file by free command.

7. mdadm monitor will open the md device every 1000 seconds
and you will find all file cache on the device are cleared.

The timing can be reduced by the following steps.

a) kill mdadm and restart it with --delay option
/sbin/mdadm --monitor --delay=30 --pid-file /var/run/mdadm/monitor.pid \
 --daemonise --scan --syslog

or open the md device directly.

sudo dd if=/dev/md/hoge of=/dev/null bs=4096 count=1

vfs: d_obtain_alias() needs to use "/" as default name.

NFS appears to use d_obtain_alias() to create the root dentry rather than
d_make_root.  This can cause 'prepend_path()' to complain that the root
has a weird name if an NFS filesystem is lazily unmounted.  e.g.  if
"/mnt" is an NFS mount then

 { cd /mnt; umount -l /mnt ; ls -l /proc/self/cwd; }

will cause a WARN message like
   WARNING: at /home/git/linux/fs/dcache.c:2624 prepend_path+0x1d7/0x1e0()
   ...
   Root dentry has weird name <>

to appear in kernel logs.

So change d_obtain_alias() to use "/" rather than "" as the anonymous
name.

CRIS: Fix I/O macros

The inb/outb macros for CRIS are broken from a number of points of view,
missing () around parameters and they have an unprotected if statement in
them.  This was breaking the compile of IPMI on CRIS and thus I was being
annoyed by build regressions, so I fixed them.

Plus I don't think they would have worked at all, since the data values
were missing "&" and the outsl had a "3" instead of a "4" for the size.
From what I can tell, this stuff is not used at all, so this can't be any
more broken than it was before, anyway.

: The reason for this is that pr_fmt() references DRIVER_NAME and is defined

: I suggest moving the DRIVER_NAME define to ms_block.c.  Cfr.  memstick.c

proc: check vma->vm_file before dereferencing

7b540d0646ce ("proc_map_files_readdir(): don't bother with grabbing
files") switched proc_map_files_readdir() to use @f_mode directly instead of
grabbing @file reference, but same time the test for @vm_file presence was
lost leading to nil dereference.  The patch brings the test back.

The all proc_map_files feature is CONFIG_\10CHECKPOINT_RESTORE wrapped
(which is set to 'n' by default) so the bug doesn't affect regular
kernels.

The regression is 3.7-rc1 only as far as I can tell.

mm: vmscan: scale number of pages reclaimed by reclaim/compaction only in direct reclaim

Jiri Slaby reported the following:

(It's an effective revert of "mm: vmscan: scale number of pages
reclaimed by reclaim/compaction based on failures".)
Given kswapd had hours of runtime in ps/top output yesterday in the
morning and after the revert it's now 2 minutes in sum for the last 24h,
I would say, it's gone.

The intention of the patch in question was to compensate for the loss of
lumpy reclaim.  Part of the reason lumpy reclaim worked is because it
aggressively reclaimed pages and this patch was meant to be a sane
compromise.

When compaction fails, it gets deferred and both compaction and
reclaim/compaction is deferred avoid excessive reclaim.  However, since
commit c6543459 ("mm: remove __GFP_NO_KSWAPD"), kswapd is woken up each
time and continues reclaiming which was not taken into account when the
patch was developed.

As it is not taking deferred compaction into account in this path it scans
aggressively before falling out and making the compaction_deferred check
in compaction_ready.  This patch avoids kswapd scaling pages for reclaim
and leaves the aggressive reclaim to the process attempting the THP
allocation.
