+ia64 and x86_64 use the number of disabled local apics in ACPI tables MADT
+to determine the number of potentially hot-pluggable cpus. The implementation
+should only rely on this to count the #of cpus, but *MUST* not rely on the
+apicid values in those tables for disabled apics. In the event BIOS doesnt
+mark such hot-pluggable cpus as disabled entries, one could use this
+parameter "additional_cpus=x" to represent those cpus in the cpu_possible_map.

+s390 uses the number of cpus it detects at IPL time to also the number of bits
+in cpu_possible_map. If it is desired to add additional cpus at a later time

-mpol=default		prefers to allocate memory from the local node
-mpol=bind		prefers to allocate from mpol_nodelist

-The following mount option is used in conjunction with mpol=interleave,
-mpol=bind or mpol=preferred:
-mpol_nodelist:	nodelist suitable for parsing with nodelist_parse.
+mpol=default             prefers to allocate memory from the local node
+mpol=prefer:Node         prefers to allocate memory from the given Node
+mpol=bind:NodeList       allocates memory only from nodes in NodeList
+mpol=interleave          prefers to allocate from each node in turn
+mpol=interleave:NodeList allocates from each node of NodeList in turn

+NodeList format is a comma-separated list of decimal numbers and ranges,
+a range being two hyphen-separated decimal numbers, the smallest and
+largest node numbers in the range.  For example, mpol=bind:0-3,5,7,9-15
+
+Note that trying to mount a tmpfs with an mpol option will fail if the
+running kernel does not support NUMA; and will fail if its nodelist
+specifies a node >= MAX_NUMNODES.  If your system relies on that tmpfs
+being mounted, but from time to time runs a kernel built without NUMA
+capability (perhaps a safe recovery kernel), or configured to support
+fewer nodes, then it is advisable to omit the mpol option from automatic
+mount options.  It can be added later, when the tmpfs is already mounted
+on MountPoint, by 'mount -o remount,mpol=Policy:NodeList MountPoint'.

-/*
- * The internal buffer is meant to store obaque blobs of data, so it doesn't
- * know of higher level concepts like triggers.
- * It consists of a number of pages that are used as a ringbuffer. Each data
- * blob is stored in a simple record that consists of an integer, which
- * contains the size of the following data, and the data bytes themselfes.
- *
- * To allow for multiple independent readers we create one internal buffer
- * each time the device is opened and destroy the buffer when the file is
- * closed again.
- *
- * One record can be written to a buffer by using the functions
- * - dasd_eer_start_record (one time per record to write the size to the buffer
- *                          and reserve the space for the data)
- * - dasd_eer_write_buffer (one or more times per record to write the data)
- * The data can be written in several steps but you will have to compute
- * the total size up front for the invocation of dasd_eer_start_record.
- * If the ringbuffer is full, dasd_eer_start_record will remove the required
- * number of old records.
- *
- * A record is typically read in two steps, first read the integer that
- * specifies the size of the following data, then read the data.
- * Both can be done by
- * - dasd_eer_read_buffer
- *
- * For all mentioned functions you need to get the bufferlock first and keep it
- * until a complete record is written or read.
- */

-
-/*
- * Alle information necessary to keep track of an internal buffer is kept in
- * a struct eerbuffer. The buffer specific to a file pointer is strored in
- * the private_data field of that file. To be able to write data to all
- * existing buffers, each buffer is also added to the bufferlist.
- * If the user doesn't want to read a complete record in one go, we have to
- * keep track of the rest of the record. residual stores the number of bytes
- * that are still to deliver. If the rest of the record is invalidated between
- * two reads then residual will be set to -1 so that the next read will fail.
- * All entries in the eerbuffer structure are protected with the bufferlock.
- * To avoid races between writing to a buffer on the one side and creating
- * and destroying buffers on the other side, the bufferlock must also be used
- * to protect the bufferlist.

-/*****************************************************************************/
-
-/*
- * When a DASD device driver wants to report an error, it calls the
- * function dasd_eer_write_trigger (via a notifier mechanism) and gives the
- * respective trigger ID as parameter.
- * Currently there are four kinds of triggers:
- *
- * DASD_EER_FATALERROR:  all kinds of unrecoverable I/O problems
- * DASD_EER_PPRCSUSPEND: PPRC was suspended
- * DASD_EER_NOPATH:      There is no path to the device left.
- * DASD_EER_STATECHANGE: The state of the device has changed.
- *
- * For the first three triggers all required information can be supplied by
- * the caller. For these triggers a record is written by the function
- * dasd_eer_write_standard_trigger.
- *
- * When dasd_eer_write_trigger is called to write a DASD_EER_STATECHANGE
- * trigger, we have to gather the necessary sense data first. We cannot queue
- * the necessary SNSS (sense subsystem status) request immediatly, since we
- * are likely to run in a deadlock situation. Instead, we schedule a
- * work_struct that calls the function dasd_eer_sense_subsystem_status to
- * create and start an SNSS  request asynchronously.
- *
- * To avoid memory allocations at runtime, the necessary memory is allocated
- * when the extended error reporting is enabled for a device (by
- * dasd_eer_probe). There is one private eer data structure for each eer
- * enabled DASD device. It contains memory for the work_struct, one SNSS cqr
- * and a flags field that is used to coordinate the use of the cqr. The call
- * to write a state change trigger can come in at any time, so we have one flag
- * CQR_IN_USE that protects the cqr itself. When this flag indicates that the
- * cqr is currently in use, dasd_eer_sense_subsystem_status cannot start a
- * second request but sets the SNSS_REQUESTED flag instead.
- *
- * When the request is finished, the callback function dasd_eer_SNSS_cb
- * is called. This function will invoke the function
- * dasd_eer_write_SNSS_trigger to finally write the trigger. It will also
- * check the SNSS_REQUESTED flag and if it is set it will call
- * dasd_eer_sense_subsystem_status again.
- *
- * To avoid race conditions during the handling of the lock, the flags must
- * be protected by the snsslock.
