We should only include support for the ISA interface of the LM78/LM79
if CONFIG_ISA is set. Not only this makes the driver somewhat smaller
on most architectures, but this also avoids poking at random I/O
ports on these architectures.

This is very similiar to what was done for the w83781d driver in
October 2008.

This patch adds a new driver for SMSC SCH5636 Super I/O chips.
The chips include an embedded microcontroller for hardware monitoring
solutions, allowing motherboard manufacturers to create their own
custom hwmon solution based upon the SCH5636.

Currently the sch5636 driver only supports the Fujitsu Theseus SCH5636
based hwmon solution. The sch5636 driver runs a sanity check on
loading to ensure it is dealing with a Fujitsu Theseus and not with
another custom SCH5636 based hwmon solution.

If we do not want to use ACLs we at least need to perform normal Unix
permission checks.  From the comment I'm not quite sure that's what
is intended, but if 0p wants to do permission checks entirely on the

This moves logic for checking the cached ACL values from low-level
filesystems into generic code.  The end result is a streamlined ACL
check that doesn't need to load the inode->i_op->check_acl pointer at
all for the common cached case.

The filesystems also don't need to check for a non-blocking RCU walk
case in their acl_check() functions, because that is all handled at a
VFS layer.

commit fec11dd9 caused
a regression when we have already mounted //server/share/a
and want to mount //server/share/a/b.

The problem is that lookup_one_len calls __lookup_hash
with nd pointer as NULL. Then __lookup_hash calls
do_revalidate in the case when dentry exists and we end
up with NULL pointer deference in cifs_d_revalidate:

if (nd->flags & LOOKUP_RCU)
	return -ECHILD;

Fix this by checking nd for NULL.

The fsync prototype change commit 02c24a82 accidentally overwrote
the ssize_t return value of xfs_file_aio_write with 0 for SYNC type

In addition xfs_file_fsync actually returns a normal negative error, so
