Add IDE_HFLAG_LEGACY_IRQS host flag to tell ide_pci_setup_ports() to set
hwif->irq to legacy IRQ 14/15 (iff hwif->irq is not already set) and convert
atiixp, piix, serverworks, sis5513 and slc90e66 host drivers to use it.
While at it:
* In piix.c add IDE_HFLAGS_PIIX define and don't use ->init_hwif for MPIIX.

Add IDE_HFLAG_ERROR_STOPS_FIFO host flag and use it instead

* Add ->mwdma_mask and ->swdma_mask to ide_pci_device_t.
* Set ide_hwif_t DMA masks using DMA masks from ide_pci_device_t in
setup-pci.c::ide_pci_setup_ports() (iff DMA base is valid and ->init_hwif
method may still override them).
* Convert IDE PCI host drivers to use ide_pci_device_t DMA masks.
While at it:
* Use ATA_{UDMA,MWDMA,SWDMA}* defines.
* hpt34x.c: add separate ide_pci_device_t instances for HPT343 and HPT345.
* serverworks.c: fix DMA masks being set before checking DMA base.
v2:
* Add missing masks to DECLARE_GENERIC_PCI_DEV() macro.

* Make ide_pci_device_t.host_flags u32 and add IDE_HFLAG_CS5520 host flag.
* Pass ide_pci_device_t *d to setup-pci.c::ide_get_or_set_dma_base()
and use d->name instead of hwif->cds->name.
* Set IDE_HFLAG_CS5520 host flag in cs5520 host driver and use it in
ide_get_or_set_dma_base() to find out which PCI BAR to use, remove no longer
needed cs5520.c::cs5520_init_setup_dma() and ide_pci_device_t.init_setup_dma.
This fixes PCI bus-mastering not being checked for CS5510/CS5520 hosts.
v2:
* It is wrong to check simplex bits on CS5510/CS5520 as v1 did.

A sysctl method was added to enable and disable debugging levels. After
further review, it was decided that there are better approaches to doing this
and the sysctl methodology isn't really desirable. This patch removes the
sysctl code from 9p.

The 9P2000 protocol requires the authentication and permission checks to be
done in the file server. For that reason every user that accesses the file
server tree has to authenticate and attach to the server separately.
Multiple users can share the same connection to the server.
Currently v9fs does a single attach and executes all I/O operations as a
single user. This makes using v9fs in multiuser environment unsafe as it
depends on the client doing the permission checking.
This patch improves the 9P2000 support by allowing every user to attach
separately. The patch defines three modes of access (new mount option
'access'):
- attach-per-user (access=user) (default mode for 9P2000.u)
If a user tries to access a file served by v9fs for the first time, v9fs
sends an attach command to the server (Tattach) specifying the user. If
the attach succeeds, the user can access the v9fs tree.
As there is no uname->uid (string->integer) mapping yet, this mode works
only with the 9P2000.u dialect.
- allow only one user to access the tree (access=<uid>)
Only the user with uid can access the v9fs tree. Other users that attempt
to access it will get EPERM error.
- do all operations as a single user (access=any) (default for 9P2000)
V9fs does a single attach and all operations are done as a single user.
If this mode is selected, the v9fs behavior is identical with the current
one.

Add missing IRQs and IRQ descriptions to /proc/interrupts.
/proc/interrupts is most useful when it displays every IRQ vector in use by
the system, not just those somebody thought would be interesting.
This patch inserts the following vector displays to the i386 and x86_64
platforms, as appropriate:
rescheduling interrupts
TLB flush interrupts
function call interrupts
thermal event interrupts
threshold interrupts
spurious interrupts
A threshold interrupt occurs when ECC memory correction is occuring at too
high a frequency. Thresholds are used by the ECC hardware as occasional
ECC failures are part of normal operation, but long sequences of ECC
failures usually indicate a memory chip that is about to fail.
Thermal event interrupts occur when a temperature threshold has been
exceeded for some CPU chip. IIRC, a thermal interrupt is also generated
when the temperature drops back to a normal level.
A spurious interrupt is an interrupt that was raised then lowered by the
device before it could be fully processed by the APIC. Hence the apic sees
the interrupt but does not know what device it came from. For this case
the APIC hardware will assume a vector of 0xff.
Rescheduling, call, and TLB flush interrupts are sent from one CPU to
another per the needs of the OS. Typically, their statistics would be used
to discover if an interrupt flood of the given type has been occuring.
AK: merged v2 and v4 which had some more tweaks
AK: replace Local interrupts with Local timer interrupts
AK: Fixed description of interrupt types.
