SCSI=m must disallow static drivers.

The problem is that all the SATA drivers depend on SCSI_SATA.

With SCSI=m and SCSI_SATA=y this allows the static enabling of the SATA
drivers with unwanted effects, e.g.:
- SCSI=m, SCSI_SATA=y, SCSI_ATA_ADMA=y
  -> SCSI_ATA_ADMA is built statically but scsi/built-in.o is not linked
     into the kernel
- SCSI=m, SCSI_SATA=y, SCSI_ATA_ADMA=y, SCSI_SATA_AHCI=m
  -> SCSI_ATA_ADMA and libata are built statically but
     scsi/built-in.o is not linked into the kernel,
     SCSI_SATA_AHCI is built modular (unresolved symbols due to missing
                                      libata)

When leaving S3 state, the AGP bridge may not have all PCI configuration
registers set in the same way as they were at boot.  This should be fixed
by pci_restore_state - however, the APBASE register cannot be set to
conflict with the APSIZE register.  If APSIZE is larger than it was before
suspend, pci_restore_state will not restore APBASE correctly.  The attached
patch adds an extra item to the agp_bridge_data structure and uses it to
store the value of APBASE.  On resume, this is then written after APSIZE
has been set.  This patch only touches the path used for Intel chipsets
without integrated graphics, and may need to be extended to work with the
others.

Without this patch, I get the symptoms described in bug 4921 - APBASE ends
up overlapping various PCI devices, and as a result they fail to work after
resume.

The #if/#ifdef cleanup exposed a bug in UML's ELF header processing.  With
this bug fixed, UML recognizes the vsyscall info coming from the host.  On
FC4, there is a vsyscall page low in the address space, which UML doesn't
provide.  This causes an infinite page fault loop and a hang on boot.

This patch works around that by making this look like a no-vsyscall system.

The patch addresses a problem with ACPI SCI interrupt entry, which gets
re-used, and the IRQ is assigned to another unrelated device.  The patch
corrects the code such that SCI IRQ is skipped and duplicate entry is
avoided.  Second issue came up with VIA chipset, the problem was caused by
original patch assigning IRQs starting 16 and up.  The VIA chipset uses
4-bit IRQ register for internal interrupt routing, and therefore cannot
handle IRQ numbers assigned to its devices.  The patch corrects this
problem by allowing PCI IRQs below 16.

Range is already set to write-back, vesafb attempts to add a write-combining

>> mtrr: size and base must be multiples of 4 kiB

This is a bug, vesafb attempts to add a size < PAGE_SIZE triggering
the messages below.

To eliminate the warning messages, you can add the option mtrr:2 to add a
write-back mtrr for vesafb.  Or just use nomtrr option.

1. Fix algorithm for finding the best power of 2 size with mtrr_add().

2. Add option to choose the mtrr type by extending the mtrr boot option:

   mtrr:n where n

        0 = no mtrr (equivalent to using the nomtrr option)
        1 = uncachable
        2 = write back
        3 = write combining (default)
        4 = write through

sync_tsc was using smp_call_function to ask the boot processor to report
it's tsc value.  smp_call_function performs an IPI_send_allbutself which is
a broadcast ipi.  There is a window during processor startup during which
the target cpu has started and before it has initialized it's interrupt
vectors so it can properly process an interrupt.  Receveing an interrupt
during that window will triple fault the cpu and do other nasty things.

Why cli does not protect us from that is beyond me.

The simple fix is to match ia64 and provide a smp_call_function_single.
Which avoids the broadcast and is more efficient.

This certainly fixes the problem of getting stuck on boot which was
very easy to trigger on my SMP Hyperthreaded Xeon, and I think
it fixes it for the right reasons.

This patch does the same swap, i.e. use the ISO macro if (isoc).
Additionally, it fixes the return value - the usb_calc_bus_time function
returns the time in nanoseconds (I didn't notice that before) while the
HS_USECS and HS_USECS_ISO are microseconds.  This fixes the function to
return nanoseconds always, and adjusts ehci-q.c (the only high-speed

This patch handles a rarely-encountered failure mode in usbcore.  It's
legal for device_add to fail (although now it happens even more rarely
than before since failure to bind a driver is no longer fatal).  So when
we destroy the interfaces in a configuration, we shouldn't try to delete
ones which weren't successfully registered.  Also, failure to register an
interface shouldn't be fatal either -- I think; you may disagree about
this part of the patch.

The setup-bus code doesn't work correctly for configurations
with more than one display adapter in the same PCI domain.
This stuff actually is a leftover of an early 2.4 PCI setup code
and apparently it stopped working after some "bridge_ctl" changes.
So the best thing we can do is just to remove it and rely on the fact
that any firmware *has* to configure VGA port forwarding for the boot
display device properly.

But then we need to ensure that the bus->bridge_ctl will always
contain valid information collected at the probe time, therefore
the following change in pci_scan_bridge() is needed.

The 24RF08 corruption prevention in the eeprom and max6875 drivers wasn't
complete. For one thing, the additional quick write should happen as soon
as possible and unconditionally, while both drivers had error paths before.
For another, when a given chip is forced, the core does not emit a quick
write, so a second quick write would cause the corruption rather than
prevent it.

I plan to move the corruption prevention in the core in the long run, so
that individual drivers don't have to care anymore. But I need to merge
