      wusb: whci-hcd shouldn't do ASL/PZL updates while channel is inactive · 56968d0c
      由 David Vrabel 提交于 
      ASL/PZL updates while the WUSB channel is inactive (i.e., the PZL and
ASL are stopped) may not complete.  This causes hangs when removing the
whci-hcd module if a device is still connected (removing the device
does an endpoint_disable which results in an ASL update to remove the
qset).

If the WUSB channel is inactive the update can simply be skipped as the
WHC doesn't care about the state of the ASL/PZL.

      uwb: add basic radio manager · 6fae35f9
      由 David Vrabel 提交于 
      The UWB radio manager coordinates the use of the radio between the
PALs that may be using it.  PALs request use of the radio with
uwb_radio_start() and the radio manager will start beaconing if its
not already doing so.  When the last PAL has called uwb_radio_stop()
beaconing will be stopped.

In the future, the radio manager will have a more sophisticated channel
selection algorithm, probably following the Channel Selection Policy
from the WiMedia Alliance when it is finalized.  For now, channel 9
(BG1, TFC1) is selected.

The user may override the channel selected by the radio manager and may
force the radio to stop beaconing.

The WUSB Host Controller PAL makes use of this and there are two new
debug PAL commands that can be used for testing.

      intel-iommu: fix compile warnings · b4e0f9eb
      由 FUJITA Tomonori 提交于 
      Impact: cleanup

I got the following warnings on IA64:

  linux-2.6/drivers/pci/intel-iommu.c: In function 'init_dmars':
  linux-2.6/drivers/pci/intel-iommu.c:1658: warning: format '%Lx' expects type 'long long unsigned int', but argument 2 has type 'u64'
  linux-2.6/drivers/pci/intel-iommu.c:1663: warning: format '%Lx' expects type 'long long unsigned int', but argument 2 has type 'u64'

Another victim of int-ll64.h versus int-l64.h confusion between platforms.

->reg_base_addr has a type of u64 - which can only be printed out
consistently if we cast its type up to LL.

[ Eventually reg_base_addr should be converted to phys_addr_t, for which
  we have the %pR printk helper - but that is out of the scope of late
  -rc's. ]
