ServerWorks CSB5 IDE fixes (from 2.4 patches by Duncan Laurie)

- blacklist drives overrunning their FIFOs in UDMA5/6 modes
- add PCI quirk (CSB5 IDE doesn't fully support native mode)

plus sync driver with 2.4 version.

SiS IDE driver fixes by Lionel Bouton:
- support for SiS655
- support for SiS630S/ET UDMA5 mode
- corrected /proc/ide/sis output for ATA133 chipsets
  (drives' positions were swapped)
- use of pci_read_config_byte() instead of direct PCI poking
  for SiS962+ detection

Add hwif->hold flag for hotswap interfaces.
Initialize founded hwif in ide_register_hw().

Original patch by Benjamin Herrenschmidt.

Fix incorrect UDMA100 cable test (by Dave Jones).
Fix compilation warning.

Add Intel ICH5 basic SATA support (from 2.4 by Andre Hedrick)
and as a bonus kill duplicate entry in piix_pci_info[].

Add IDE support for VIA vt8237 southbridge.

To handle control messaging in contexts other than the
IRQ handler's setup() callback, a bit of automagic needed
to be removed; and some minor bugs fixed.

This is the addition needed to make my previous patch for the UHCI
controller work properly with PM suspend/resume.

Paul:

Okay, I think this patch ought to do the trick.  I modified the PM
suspend/resume code so that on buggy motherboards like yours the suspend
routine really does a reset, while on normal motherboards the resume
routine really does a resume.  I haven't tried that part out because,
truth to tell, I'm a little scared of doing an APM/ACPI suspend.  Not long
ago I walked away from my computer for about a half-hour, leaving 2.5.69
running.  When I got back the screen was blank and the machine was totally
non-responsive.

I changed the delays in reset_hc() to use schedule_timeout() rather than
wait_ms(), which should make it more friendly.

Finally, I put the USBCMD_FGR back into wakeup_hc().  The reason for it is
now evident: a wakeup might be the result of a system-initiated event
as opposed to something requested by a device.

I think I'd better work on my plausible deniability...

This resolves some problems in the endpoint disable
patch I sent recently:

  - wasn't un-halting some endpoints
  - was clobbering ep0 setup in some cases.

Lots of changes that have accumulated over the last weeks.

This makes it compile and boot again, Lots of bug fixes, including
security fixes.  Several speedups.

Only changes x86-64 specific files.

 - Use private copy of siginfo.h (for si_band)
 - Align 32bit vsyscall coredump (from Roland McGrath)
 - First steps towards 64bit vsyscall coredump (not working yet)
 - Use in kernel trampoline for signals
 - Merge APIC pm update from Pavel/Mikael
 - Security fix for ioperm (from i386)
 - Reenable vsyscall dumping for 32bit coredumps
 - Fix bugs in 32bit coredump that could lead to oopses.
 - Fix 64bit vsyscalls
 - Revert change in pci-gart.c: pci_alloc_consistent must use an
   0xffffffff mask hardcoded.
 - Fix bug in noexec= option handling
 - Export fake_node
 - Cleanups from Pavel
 - Disable 32bit vsyscall coredump again.  Still has some problems.
 - Implement new noexec= and noexec32= options to give a wide choice
   of support for non executable mappings for 32bit and 64bit processes.
   The default is now to honor PROT_EXEC, but mark stack and heap
   PROT_EXEC.
 - 32bit emulation changes from Pavel: use compat_* types.
 - (2.4) Use physical address for GART register.
 - Convert debugreg array to individual members and clean up ptrace
   access.  This saves 16 byte per task.
 - (2.4) Use new streamlined context switch code.  This avoids a
   pipeline stall and pushes the register saving to C code.
 - Save flags register in context switch
 - Clean up SMP early bootup.  Remove some unnecessary code.
 - (2.4) Process numa= option early
 - (2.4) Merge 2.4 clear_page, copy_*_user, copy_page, memcpy, memset.
   These are much faster.  clear/copy_page don't force the new page out
   of memory now which should speed up user processes.  Also full
   workaround for errata #91.
 - Some cleanup in pageattr.c code.
 - Fix warning in i387.h
 - Fix wrong PAGE_KERNEL_LARGE define.  This fixes a security hole and
   makes AGP work again.
 - Fix wrong segment exception handler to not crash.
 - Fix incorrect swapgs handling in bad iret exception handling
 - Clean up some boot printks
 - Micro optimize exception handling preamble.
 - New reboot handling.  Supports warm reboot and BIOS reboot vector
   reboot now.
 - (2.4) Use MTRRs by default in vesafb
 - Fix bug in put_dirty_page: use correct page permissions for the stack
 - Fix type of si_band in asm-generic/siginfo.h to match POSIX/glibc
   (needs checking with other architecture maintainers)
 - (2.4) Define ARCH_HAS_NMI_WATCHDOG
 - Minor cleanup in calling.h
 - IOMMU tuning: only flush the GART TLB when the IOMMU aperture area
   allocation wraps.  Also don't clear entries until needed.  This
   should increase IO performance for IOMMU devices greatly.  Still a
   bit experimental, handle with care.
 - Unmap the IOMMU aperture from kernel mapping to prevent unwanted CPU
   prefetches.
 - Make IOMMU_LEAK_TRACE depend on IOMMU_DEBUG
 - Fix minor bug in pci_alloc_consistent - always check against the dma
   mask of the device, not 0xffffffff.
 - Remove streamining mapping delayed flush in IOMMU: not needed anymore
   and didn't work correctly in 2.5 anyways.
 - Fix the bad pte warnings caused by the SMP/APIC bootup.
 - Forward port 2.4 fix: ioperm was changing the wrong io ports in some
   cases.
 - Minor cleanups
 - Some cleanups in pageattr.c (still buggy)
 - Fix some bugs in the AGP driver.
 - Forward port from 2.4: mask all reserved bits in debug register in
   ptrace.  Previously gdb could crash the kernel by passing invalid
   values.
 - Security fix: make sure FPU is in a defined state after an
   FXSAVE/FXRSTOR exception occurred.
 - Eats keys on panic (works around a buggy KVM)
 - Make user.h user includeable.
 - Disable sign compare warnings for gcc 3.3-hammer
 - Use DSO for 32bit vsyscalls and dump it in core dumps.  Add dwarf2
   information for the vsyscalls.
   Thanks to Richard Henderson for helping me with the nasty parts of
   it.  I had to do some changes over his patch and it's currently only
   lightly tested.  Handle with care.  This only affects 32bit programs
   that use a glibc 3.2 with sysenter support.
 - Security fixes for the 32bit ioctl handlers.  Also some simplications
   and speedups.
 - gcc 3.3-hammer compile fixes for inline assembly
 - Remove acpi.c file corpse.
 - Lots of warning fixes
 - Disable some Dprintks to make the bootup quieter again
 - Clean up ptrace a bit (together with warning fixes)
 - Merge with i386 (handle ACPI dynamic irq entries properly)
 - Disable change_page_attr in pci-gart for now.  Strictly that's
   incorrect, need to do more testing for the root cause of the current
   IOMMU problems.
 - Update defconfig
 - Disable first prefetch in copy_user that is likely to trigger Opteron
   Errata #91
 - More irqreturn_t fixes
 - Add pte_user and fix the vsyscall ptrace hack in generic code.
   It's still partly broken
 - Port verbose MCE handler from 2.4

The calling task must have a valid reclaim_state when running page
reclaim.  But I had forgotten about shrink_all_memory().

Move the PCI core to start using these, enabling proper reference counting
on struct pci_dev.
