HW feature related frame/buffer size calculation") wrongly removed

This patch fixes the issue, plus fixes following sparse warning
introduced by the same commit:
gianfar.c:1406:13: warning: context imbalance in 'gfar_vlan_rx_register' - wrong count at exit

gfar_vlan_rx_register() checks for "if (old_grp == grp)" and tries
to return w/o dropping the lock.

According to net/8021q/vlan.c VLAN core issues rx_register() callback:
1. In register_vlan_dev() only on a newly created group;
2. In unregister_vlan_dev() only if the group becomes empty.

Thus the check in the gianfar driver isn't needed.

inotify: clean up inotify_read and fix locking problems

If userspace supplies an invalid pointer to a read() of an inotify
instance, the inotify device's event list mutex is unlocked twice.
This causes an unbalance which effectively leaves the data structure
unprotected, and we can trigger oopses by accessing the inotify
instance from different tasks concurrently.

The best fix (contributed largely by Linus) is a total rewrite
of the function in question:

15 years agosata_mv: Properly initialize main irq mask
Thomas Reitmayr [Sat, 24 Jan 2009 19:24:58 +0000 (20:24 +0100)]
sata_mv: Properly initialize main irq mask

I noticed that during initialization sata_mv.c assumes that the main
interrupt mask has its default value of 0. The function
mv_platform_probe(..) initializes a shadow irq mask with 0 assuming
that's the value of the controller's register. Now
mv_set_main_irq_mask(..) only writes the controller's register if the
new value differs from the "shadowed" value. This is fatal when trying
to disable all interrupts in mv_init_host(..), i.e. the following
function call does not write anything to the main irq mask register:

  mv_set_main_irq_mask(host, ~0, 0);

The effect I see on my machine (QNAP TS-109 II) with booting via kexec
(with Linux as a 2nd-stage boot loader) is that if the sata_mv module
was still loaded when performing kexec, then the new kernel's sata_mv
module starts up with interrupts enabled. This results in an unhandled
IRQ and breaks the boot process.

The unhandled interrupt itself might also be fixed by Lennert's patch
proposed at http://markmail.org/message/kwvzxstnlsa3s26w which I did not
try yet.

However I still propose to additionally initialize the shadow variable
with the current contents of the main irq mask register to get both in
sync and allow proper disabling the main irq mask. This fixes the
unhandled irq on my machine.

sata_nv: fix MCP5x reset

MCP5x family of controllers seem to share much more with nf2's as far
as reset protocol is concerned.  It requires heardreset to get the PHY
going and classfication code report after hardreset is unreliable.
Create a new board type MCP5x and use noclassify hardreset.  SWNCQ is
modified to inherit from this new type.

This fixes hotplug regression reported in kernel bz#12351.
