We use a bit in the thread_info flags for this.  The bit is cleared on syscall
entry and set by force_successful_syscall_return.  If the bit is set on syscall
exit, the normal check whether the value from the syscall function is an
error code is disabled and the value is just returned to userspace.

This adds the missing arch/sh/tools directory, which includes mach-type
generation scripts for building include/asm-sh/machtypes.h.

drivers/hotplug/Kconfig moved to drivers/pci/hotplug/Kconfig.

This updates arch/sh/Kconfig respectively.

* replace the pci_alloc_consistent calls with dma_alloc_coherent
  because we want to do the allocations at GFP_KERNEL priority and
  not GFP_ATOMIC because we request quite a bit of memory and the
  allocation fails quite frequently.

  It would be better to have a pci_alloc_consistent with an extra
  parameter (priority) but since we haven't, and the meye driver is
  supposed to work only on ix86 platforms we can safely do the
  change.

* fix the DMA engine stop request. The hard freezes encountered
  when using this driver and repeatedly opening/closing the device
  have been tracked down to this particular piece of code. The new
  version seems to work way better, I haven't had a single freeze
  since the change.

* fix the irq handler prototype (irqreturn_t changes).

* fix a hang problem when loading the driver on (at least) a
  PCG-FX105k. Thanks to Jozef Kruger for reporting the problem
  and testing different versions of this fix.

* fix a .text.exit problem in the sonypi driver related to the
  recent PM changes (thanks to Adrian Bunk for the patch).

* fix the irq handling reports (make sonypi always report IRQ_HANDLED)
  because there *are* events belonging to the sonypi device which
  are not (yet) recognized by the driver and we don't want those
  to pollute the logs...

* test if the ACPI subsystem is not disabled before trying to
  use its ec_read/ec_write methods.

* fix the hangs when enabling bluetooth (thanks to Daniel K. for
  the patch).

* other miscellaneous small fixes.

Use local_irq_[disable|enable]() instead of hand-coded asm.

This fixes the problems with NFS that got triggered by the list
poisoning.

The problem is that whereas using the dentry->d_hash list for private
purposes was previously harmless, it is not allowed with the RCU lists,
because we depend on the unhashed node continuing to point back to the
original list.

So keep a small vector of dentries around instead of using the d_hash
list to keep track of them.

This patch changes network devices to run hotplug out of the
kobject/class_device infrastructure rather than calling it
from the network code.  The code gets simpler and there is
only one place for Greg to fix when he changes the API.

All hotplug now happens off the chain:
     rtnl_unlock -> netdev_run_todo -> netdev_sysfs_{un}register

The state flag deadbeef was converted to a state enumeration tp
handle necessary book keeping, and adds some defense against
drivers that have unexpected semantics.

Split the dm_create() function into two variants, depending on whether you
want the device to have a specific minor number.  This avoids the broken
overloading of the minor argument to the old dm_create().
