cbd92ce62e Eliminate the overhead of gratuitous repeated reinitialization of cap_rights 
- Add macros to allow preinitialization of cap_rights_t.

- Convert most commonly used code paths to use preinitialized cap_rights_t.
  A 3.6% speedup in fstat was measured with this change.

4b70609941 Optimise use of Giant in the LinuxKPI. 
- Make sure Giant is locked when calling PCI device methods.
Newbus currently requires this.

- Avoid unlocking Giant right before aquiring the sleepqueue lock.
This can save a task switch.

the linux_pci_find_irq_dev() function else IRQs can be requested from

be15e1332d Implement proper support for complete_all() in the LinuxKPI. 
When complete_all() is called there might be multiple waiters. The
current implementation could only handle one waiter. Make sure the
completion is sticky when complete_all() is called to be compatible

2c0f13aa59 vm_wait() rework. 
Make vm_wait() take the vm_object argument which specifies the domain
set to wait for the min condition pass.  If there is no object
associated with the wait, use curthread' policy domainset.  The
mechanics of the wait in vm_wait() and vm_wait_domain() is supplied by
the new helper vm_wait_doms(), which directly takes the bitmask of the
domains to wait for passing min condition.

Eliminate pagedaemon_wait().  vm_domain_clear() handles the same
operations.

Eliminate VM_WAIT and VM_WAITPFAULT macros, the direct functions calls
are enough.

Eliminate several control state variables from vm_domain, unneeded
after the vm_wait() conversion.
