+ * Each subsystem defined by sysctl defines a list of variables

+ * type given below. Each sysctl level defines a set of name/type
+ * pairs to be used by sysctl(1) in manipulating the subsystem.
+ *
+ * When declaring new sysctl names, use the CTLFLAG_LOCKED flag in the
+ * type to indicate that all necessary locking will be handled
+ * within the sysctl.
+ *
+ * Any sysctl defined without CTLFLAG_LOCKED is considered legacy
+ * and will be protected by a global mutex.
+ *
+ * Note:	This is not optimal, so it is best to handle locking
+ *		yourself, if you are able to do so.  A simple design
+ *		pattern for use to avoid in a single function known
+ *		to potentially be in the paging path ot doing a DMA
+ *		to physical memory in a user space process is:
+ *
+ *			lock
+ *			perform operation vs. local buffer
+ *			unlock
+ *			SYSCTL_OUT(rey, local buffer, length)
+ *
+ *		...this assumes you are not using a deep call graph
+ *		or are unable to pass a local buffer address as a
+ *		parameter into your deep call graph.
+ *
+ *		Note that very large user buffers can fail the wire
+ *		if to do so would require more physical pages than
+ *		are available (the caller will get an ENOMEM error,
+ *		see sysctl_mem_hold() for details).

+ * XXX This information should be moved to the man page.
+ *
+ * These are the support HW selectors for sysctlbyname.  Parameters that are byte counts or frequencies are 64 bit numbers.
+ * All other parameters are 32 bit numbers.
+ *
+ *   hw.memsize                - The number of bytes of physical memory in the system.
+ *
+ *   hw.ncpu                   - The maximum number of processors that could be available this boot.
+ *                               Use this value for sizing of static per processor arrays; i.e. processor load statistics.
+ *
+ *   hw.activecpu              - The number of processors currently available for executing threads.
+ *                               Use this number to determine the number threads to create in SMP aware applications.
+ *                               This number can change when power management modes are changed.
+ *
+ *   hw.physicalcpu            - The number of physical processors available in the current power management mode.
+ *   hw.physicalcpu_max        - The maximum number of physical processors that could be available this boot
+ *
+ *   hw.logicalcpu             - The number of logical processors available in the current power management mode.
+ *   hw.logicalcpu_max         - The maximum number of logical processors that could be available this boot
+ *
+ *   hw.tbfrequency            - This gives the time base frequency used by the OS and is the basis of all timing services.
+ *                               In general is is better to use mach's or higher level timing services, but this value
+ *                               is needed to convert the PPC Time Base registers to real time.
+ *
+ *   hw.cpufrequency           - These values provide the current, min and max cpu frequency.  The min and max are for
+ *   hw.cpufrequency_max       - all power management modes.  The current frequency is the max frequency in the current mode.
+ *   hw.cpufrequency_min       - All frequencies are in Hz.
+ *
+ *   hw.busfrequency           - These values provide the current, min and max bus frequency.  The min and max are for
+ *   hw.busfrequency_max       - all power management modes.  The current frequency is the max frequency in the current mode.
+ *   hw.busfrequency_min       - All frequencies are in Hz.
+ *
+ *   hw.cputype                - These values provide the mach-o cpu type and subtype.  A complete list is in <mach/machine.h>
+ *   hw.cpusubtype             - These values should be used to determine what processor family the running cpu is from so that
+ *                               the best binary can be chosen, or the best dynamic code generated.  They should not be used
+ *                               to determine if a given processor feature is available.
+ *   hw.cputhreadtype          - This value will be present if the processor supports threads.  Like hw.cpusubtype this selector
+ *                               should not be used to infer features, and only used to name the processors thread architecture.
+ *                               The values are defined in <mach/machine.h>
+ *
+ *   hw.byteorder              - Gives the byte order of the processor.  4321 for big endian, 1234 for little.
+ *
+ *   hw.pagesize               - Gives the size in bytes of the pages used by the processor and VM system.
+ *
+ *   hw.cachelinesize          - Gives the size in bytes of the processor's cache lines.
+ *                               This value should be use to control the strides of loops that use cache control instructions
+ *                               like dcbz, dcbt or dcbst.
+ *
+ *   hw.l1dcachesize           - These values provide the size in bytes of the L1, L2 and L3 caches.  If a cache is not present
+ *   hw.l1icachesize           - then the selector will return and error.
+ *   hw.l2cachesize            -
+ *   hw.l3cachesize            -
+ *
+ *   hw.packages               - Gives the number of processor packages.
+ *
+ * These are the selectors for optional processor features for specific processors.  Selectors that return errors are not support
+ * on the system.  Supported features will return 1 if they are recommended or 0 if they are supported but are not expected to help .
+ * performance.  Future versions of these selectors may return larger values as necessary so it is best to test for non zero.
+ *
+ * For PowerPC:
+ *
+ *   hw.optional.floatingpoint - Floating Point Instructions
+ *   hw.optional.altivec       - AltiVec Instructions
+ *   hw.optional.graphicsops   - Graphics Operations
+ *   hw.optional.64bitops      - 64-bit Instructions
+ *   hw.optional.fsqrt         - HW Floating Point Square Root Instruction
+ *   hw.optional.stfiwx        - Store Floating Point as Integer Word Indexed Instructions
+ *   hw.optional.dcba          - Data Cache Block Allocate Instruction
+ *   hw.optional.datastreams   - Data Streams Instructions
+ *   hw.optional.dcbtstreams   - Data Cache Block Touch Steams Instruction Form
+ *
+ * For x86 Architecture:
