PARTIAL_ALLOC	Do a "partial allocation", which means that not all of the frames specified in the frame count size actually have to be allocated. This means that if the allocator was unable to find a physical memory range large enough, it can instead return whatever range it decides is optimal. Thus, instead of letting one driver get an expensive 128MiB physical memory range when the physical memory has become fragmented, and failing, it can instead be given a more optimal range. If the device supports scatter-gather lists, then the driver only has to allocate more ranges, and the device will do vectored I/O.
PARTIAL_ALLOC_STRATEGY_MASK	The bitmask of the partial allocation strategy. Currently four different strategies are supported. If PARTIAL_ALLOC is not set, this bitmask is no longer reserved.
PHYSMAP_NO_CACHE
PHYSMAP_WRITE
PHYSMAP_WRITE_COMBINE
PROT_EXEC
PROT_NONE
PROT_READ
PROT_WRITE
PTRACE_EVENT_CLONE	Sent when a child is cloned, giving you the opportunity to trace it. If you don't catch this, the child is started as normal.
PTRACE_EVENT_MASK
PTRACE_FLAG_IGNORE	Special meaning, depending on the event. Usually, when fired before an action, it will skip performing that action.
PTRACE_FLAG_MASK
PTRACE_STOP_BREAKPOINT	Stop on a software breakpoint, such as the int3 instruction for x86_64.
PTRACE_STOP_EXIT	Stop just before exiting for good.
PTRACE_STOP_MASK
PTRACE_STOP_POST_SYSCALL	Stop after a syscall is handled.
PTRACE_STOP_PRE_SYSCALL	Stop before a syscall is handled. Send PTRACE_FLAG_IGNORE to not handle the syscall.
PTRACE_STOP_SIGNAL	Stop before a signal is handled. Send PTRACE_FLAG_IGNORE to not handle signal.
PTRACE_STOP_SINGLESTEP	Stop after exactly one instruction. TODO: This may not handle fexec/signal boundaries. Should it?

SPACE_32	Only allocate memory within the 32-bit physical memory space. This is necessary for some devices may not support 64-bit memory.
SPACE_64	The frame that will be allocated, is going to reside anywhere in 64-bit space. This flag is redundant for the most part, except when overriding some other default.

Functions

wcoredump	True if status indicates a core dump was created.
wexitstatus	If wifexited(status), the exit status.
wifcontinued	True if status indicates the child continued after a stop.
wifexited	True if status indicates normal termination.
wifsignaled	True if STATUS indicates termination by a signal.
wifstopped	True if status indicates the child is stopped.
wstopsig	If wifstopped(status), the signal that stopped the child.
wtermsig	If wifsignaled(status), the terminating signal.
