SuSE discovered this problem with chown and ATTR_GID.  Make sure user
is authorized to change the group, CAN-2004-0497.

It's one of the rare files that has almost no includes
what-so-ever, so it actually never got NULL any other
way.

Two years ago, OGAWA Hirofumi removed some ugly code and
added a few simple tests to the FAT filesystem code,
intended to avoid recognizing non-FAT as FAT (for people who
fail to specify rootfstype=, forcing the kernel to guess).

That worked fairly well, until this year.

I have now seen a thread in Czech and a report from Holland that
involved the "FAT: bogus sectors-per-track value" error message.

The patch below removes this test again. The advantage is that
some real-life FAT filesystems can be mounted again.

The disadvantage that more non-FAT fss will be accepted as FAT.

Please review and apply the following patch if you find it agreeable.

This patch does not make any functional changes, but does improve
both performance and memory usage by rearranging structure elements.

The need for these changes became appearent during a code review of
the disassembly involving this structure. The memory footprint of this
structure is made smaller by grouping the byte fields next to each other.
The access of the list_head can be simplified by making it the first element
of the structure, thus avoiding a needless add-immediate without negatively
impacting any of the other accesses.

This patch adds some PCI Express register constants to <linux/pci.h>

For my device, setting the Max_Read_Request_Size value in the PCI
Express device control register makes a huge performance difference.
I wanted my driver code that does this to be a little more
self-documenting than:

	pci_read_config_word(mdev->pdev, cap + 8, &val);
	val = (val & ~(5 << 12)) | (5 << 12);

I went a little overboard and added all the basic device register
fields.  If desired I could go even further overboard and add the
link, slot and root registers as well.

This patch is based on Matthew Wilcox's patch for pciutils, corrected
for some PCI Express spec 1.0a changes.
