sysfs, it doesn't expect those files to exist already.  But when an
interface is registered, its driver may call usb_set_interface() and
thereby cause the sysfs files to be created.  The result is an error

ahci: ahci: implement workaround for ASUS P5W-DH Deluxe ahci_broken_hardreset(), take #2

P5W-DH Deluxe has ICH9 which doesn't have PMP support but SIMG 4726
hardwired to the second port of AHCI controller at PCI device 1f.2.
The 4726 doesn't work as PMP but as a storage processor which can do
hardware RAID on downstream ports.

When no device is attached to the downstream port of the 4726, pseudo
ATA device for configuration appears.  Unfortunately, ATA emulation on
the device is very lousy and causes long hang during boot.

This patch implements workaround for the board.  If the mainboard is
P5W-DH Deluxe (matched using DMI), only hardreset is used on the
second port of AHCI controller @ 1f.2 and the hardreset doesn't depend
on receiving the first FIS and just proceed to IDENTIFY.

This workaround fixes bugzilla #8923.

Milton Miller [Wed, 24 Oct 2007 16:23:48 +0000 (18:23 +0200)]
sched: fix sched_domain sysctl registration again

commit  029190c515f15f512ac85de8fc686d4dbd0ae731 (cpuset
sched_load_balance flag) was not tested SCHED_DEBUG enabled as
committed as it dereferences NULL when used and it reordered
the sysctl registration to cause it to never show any domains
or their tunables.

Fixes:

1) restore arch_init_sched_domains ordering
we can't walk the domains before we build them

presently we register cpus with empty directories (no domain
directories or files).

2) make unregister_sched_domain_sysctl do nothing when already unregistered
detach_destroy_domains is now called one set of cpus at a time
unregister_syctl dereferences NULL if called with a null.

While the the function would always dereference null if called
twice, in the previous code it was always called once and then
was followed a register.  So only the hidden bug of the
sysctl_root_table not being allocated followed by an attempt to
free it would have shown the error.

3) always call unregister and register in partition_sched_domains
The code is "smart" about unregistering only needed domains.
Since we aren't guaranteed any calls to unregister, always
unregister.   Without calling register on the way out we
will not have a table or any sysctl tree.

4) warn if register is called without unregistering
The previous table memory is lost, leaving pointers to the
later freed memory in sysctl and leaking the memory of the
tables.

Before this patch on a 2-core 4-thread box compiled for SMT and NUMA,
the domains appear empty (there are actually 3 levels per cpu).  And as
soon as two domains a null pointer is dereferenced (unreliable in this
case is stack garbage):
