| H A D | spinlock_types.h | 84eb950d Fri Jul 02 17:26:36 CDT 2010 Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com> x86, ticketlock: Clean up types and accessors
A few cleanups to the way spinlocks are defined and accessed:
- define __ticket_t which is the size of a spinlock ticket (ie, enough
bits to hold all the cpus)
- Define struct arch_spinlock as a union containing plain slock and
the head and tail tickets
- Use head and tail to implement some of the spinlock predicates.
- Make all ticket variables unsigned.
- Use TICKET_SHIFT to form constants
Most of this will be used in later patches.
