+ * The legacy ABI and the new ARM EABI have different rules making some

+ * Most notably, Eabi says 64-bit members should be 64-bit aligned instead of

+ * member it contains instead of the invariant 32-bit.
+ *
+ * The following syscalls are affected:
+ *
+ * sys_stat64:
+ * sys_lstat64:
+ * sys_fstat64:
+ *
+ *   struct stat64 has different sizes and some members are shifted
+ *   Compatibility wrappers are needed for them and provided below.
+ *
+ * sys_fcntl64:
+ *
+ *   struct flock64 has different sizes and some members are shifted
+ *   A compatibility wrapper is needed and provided below.
+ *
+ * sys_statfs64:
+ * sys_fstatfs64:
+ *
+ *   struct statfs64 has extra padding with EABI growing its size from
+ *   84 to 88.  This struct is now __attribute__((packed,aligned(4)))
+ *   with a small assembly wrapper to force the sz argument to 84 if it is 88
+ *   to avoid copying the extra padding over user space unexpecting it.
+ *
+ * sys_newuname:
+ *
+ *   struct new_utsname has no padding with EABI.  No problem there.
+ *
+ * sys_epoll_ctl:
+ * sys_epoll_wait:
+ *
+ *   struct epoll_event has its second member shifted also affecting the
+ *   structure size. Compatibility wrappers are needed and provided below.
+ *
+ * sys_ipc:
+ * sys_semop:
+ * sys_semtimedop:
+ *
+ *   struct sembuf loses its padding with EABI.  Since arrays of them are

-               Protect plain 6x86s (and other processors without the

-    19990210   Richard Gooch <rgooch@atnf.csiro.au>

-    19990212   Zoltán Böszörményi <zboszor@mail.externet.hu>
-               Major rewrite of cyrix_arr_init(): do not touch ARRs,
-               leave them as the BIOS have set them up.
-               Enable usage of all 8 ARRs.
-               Avoid multiplications by 3 everywhere and other

-    19990213   Zoltán Böszörményi <zboszor@mail.externet.hu>
-               Set up other Cyrix processors identical to the boot cpu.
-               Since Cyrix don't support Intel APIC, this is l'art pour l'art.
-               Weigh ARRs by size:
-               If size <= 32M is given, set up ARR# we were given.
-               If size >  32M is given, set up ARR7 only if it is free,
-               fail otherwise.
-    19990214   Zoltán Böszörményi <zboszor@mail.externet.hu>
-               Also check for size >= 256K if we are to set up ARR7,
-               mtrr_add() returns the value it gets from set_mtrr()
-    19990218   Zoltán Böszörményi <zboszor@mail.externet.hu>
-               Remove Cyrix "coma bug" workaround from here.
-               Moved to linux/arch/i386/kernel/setup.c and
-               linux/include/asm-i386/bugs.h
-    19990228   Richard Gooch <rgooch@atnf.csiro.au>
-	       Added MTRRIOC_KILL_ENTRY ioctl(2)
-	       Trap for counter underflow in <mtrr_file_del>.
-	       Trap for 4 MiB aligned regions for PPro, stepping <= 7.
-    19990301   Richard Gooch <rgooch@atnf.csiro.au>
-	       Created <get_free_region> hook.
-    19990305   Richard Gooch <rgooch@atnf.csiro.au>
-	       Temporarily disable AMD support now MTRR capability flag is set.
-  v1.32
-    19990308   Zoltán Böszörményi <zboszor@mail.externet.hu>
-	       Adjust my changes (19990212-19990218) to Richard Gooch's
-	       latest changes. (19990228-19990305)
-  v1.33
-    19990309   Richard Gooch <rgooch@atnf.csiro.au>
-	       Fixed typo in <printk> message.
-    19990310   Richard Gooch <rgooch@atnf.csiro.au>
-	       Support K6-II/III based on Alan Cox's <alan@redhat.com> patches.
-  v1.34
-    19990511   Bart Hartgers <bart@etpmod.phys.tue.nl>
-	       Support Centaur C6 MCR's.
-    19990512   Richard Gooch <rgooch@atnf.csiro.au>
-	       Minor cleanups.
-  v1.35
-    19990707   Zoltán Böszörményi <zboszor@mail.externet.hu>
-               Check whether ARR3 is protected in cyrix_get_free_region()
-               and mtrr_del(). The code won't attempt to delete or change it
-               from now on if the BIOS protected ARR3. It silently skips ARR3
-               in cyrix_get_free_region() or returns with an error code from
-               mtrr_del().
-    19990711   Zoltán Böszörményi <zboszor@mail.externet.hu>
-               Reset some bits in the CCRs in cyrix_arr_init() to disable SMM
-               if ARR3 isn't protected. This is needed because if SMM is active
-               and ARR3 isn't protected then deleting and setting ARR3 again
-               may lock up the processor. With SMM entirely disabled, it does
-               not happen.
-    19990812   Zoltán Böszörményi <zboszor@mail.externet.hu>
-               Rearrange switch() statements so the driver accomodates to
-               the fact that the AMD Athlon handles its MTRRs the same way
-               as Intel does.
-    19990814   Zoltán Böszörményi <zboszor@mail.externet.hu>
-	       Double check for Intel in mtrr_add()'s big switch() because
-	       that revision check is only valid for Intel CPUs.
-    19990819   Alan Cox <alan@redhat.com>
-               Tested Zoltan's changes on a pre production Athlon - 100%
-               success.
-    19991008   Manfred Spraul <manfreds@colorfullife.com>
-    	       replaced spin_lock_reschedule() with a normal semaphore.
-  v1.36
-    20000221   Richard Gooch <rgooch@atnf.csiro.au>
-               Compile fix if procfs and devfs not enabled.
-	       Formatting changes.

-               Ugh, I broke AMD support.

-
-  v1.40
-    20010327   Dave Jones <davej@suse.de>
-	       Adapted Cyrix III support to include VIA C3.
-
-  v2.0
-    20020306   Patrick Mochel <mochel@osdl.org>
-               Split mtrr.c -> mtrr/*.c
-               Converted to Linux Kernel Coding Style
-               Fixed several minor nits in form
-               Moved some SMP-only functions out, so they can be used
-                for power management in the future.
-               TODO: Fix user interface cruft.

- * the reserved page
- *
- *   SAL reserves one page of memory per partition for XPC. Though a full page
- *   in length (16384 bytes), its starting address is not page aligned, but it
- *   is cacheline aligned. The reserved page consists of the following:
- *
- *   reserved page header
- *
- *     The first cacheline of the reserved page contains the header
- *     (struct xpc_rsvd_page). Before SAL initialization has completed,
- *     SAL has set up the following fields of the reserved page header:
- *     SAL_signature, SAL_version, partid, and nasids_size. The other
- *     fields are set up by XPC. (xpc_rsvd_page points to the local
- *     partition's reserved page.)
- *
- *   part_nasids mask
- *   mach_nasids mask
- *
- *     SAL also sets up two bitmaps (or masks), one that reflects the actual
- *     nasids in this partition (part_nasids), and the other that reflects
- *     the actual nasids in the entire machine (mach_nasids). We're only
- *     interested in the even numbered nasids (which contain the processors
- *     and/or memory), so we only need half as many bits to represent the
- *     nasids. The part_nasids mask is located starting at the first cacheline
- *     following the reserved page header. The mach_nasids mask follows right
- *     after the part_nasids mask. The size in bytes of each mask is reflected
- *     by the reserved page header field 'nasids_size'. (Local partition's
- *     mask pointers are xpc_part_nasids and xpc_mach_nasids.)
- *
- *   vars
- *   vars part
- *
- *     Immediately following the mach_nasids mask are the XPC variables
- *     required by other partitions. First are those that are generic to all
- *     partitions (vars), followed on the next available cacheline by those
- *     which are partition specific (vars part). These are setup by XPC.
- *     (Local partition's vars pointers are xpc_vars and xpc_vars_part.)
- *
- * Note: Until vars_pa is set, the partition XPC code has not been initialized.

+ *	  shared between expansion ROMs and other resource regions, it's
+ *	  at least dangerous)
+ *
+ *  Our solution:
+ *	(1) Allocate resources for all buses behind PCI-to-PCI bridges.
+ *	    This gives us fixed barriers on where we can allocate.
+ *	(2) Allocate resources for all enabled devices.  If there is
+ *	    a collision, just mark the resource as unallocated. Also
+ *	    disable expansion ROMs during this step.
+ *	(3) Try to allocate resources for disabled devices.  If the
+ *	    resources were assigned correctly, everything goes well,
+ *	    if they weren't, they won't disturb allocation of other
+ *	    resources.
+ *	(4) Assign new addresses to resources which were either
+ *	    not configured at all or misconfigured.  If explicitly
+ *	    requested by the user, configure expansion ROM address

- *  This file contains some low-level i2c access routines that
- *  need to be used by various bits of the PowerMac platform code
- *  at times where the real asynchronous & interrupt driven driver
- *  cannot be used. The API borrows some semantics from the darwin
- *  driver in order to ease the implementation of the platform
- *  properties parser
+ * The linux i2c layer isn't completely suitable for our needs for various
+ * reasons ranging from too late initialisation to semantics not perfectly
+ * matching some requirements of the apple platform functions etc...
+ *
+ * This file thus provides a simple low level unified i2c interface for
+ * powermac that covers the various types of i2c busses used in Apple machines.
+ * For now, keywest, PMU and SMU, though we could add Cuda, or other bit
+ * banging busses found on older chipstes in earlier machines if we ever need
+ * one of them.
+ *
+ * The drivers in this file are synchronous/blocking. In addition, the
+ * keywest one is fairly slow due to the use of msleep instead of interrupts
+ * as the interrupt is currently used by i2c-keywest. In the long run, we
+ * might want to get rid of those high-level interfaces to linux i2c layer
+ * either completely (converting all drivers) or replacing them all with a
+ * single stub driver on top of this one. Once done, the interrupt will be
+ * available for our use.

+	  kexec is a system call that implements the ability to shutdown your
+	  current kernel, and to start another kernel.  It is like a reboot
+	  but it is indepedent of the system firmware.  And like a reboot
+	  you can start any kernel with it, not just Linux.
+
+	  The name comes from the similiarity to the exec system call.
+
+	  It is an ongoing process to be certain the hardware in a machine
+	  is properly shutdown, so do not be surprised if this code does not
+	  initially work for you.  It may help to enable device hotplugging
+	  support.  As of this writing the exact hardware interface is
+	  strongly in flux, so no good recommendation can be made.
