As per Documentation/SubmittingPatches

By Urban Widmark

Most work done by Paul Gortmaker. More work needed.

Marc Singer noticed some BIOSen on the AMD Elan
alias the cpu frequency registers in a place that some
drivers probe during bootup. Result - changed CPU speed
after booting.

The fix is to unmap the alias.

Marc put a patch forward for 2.2, this one is cooked up
by me, but is currently untested but functionally equivalent.

(is already in drivers/char/agp/Config.help)

The smp_call_function() does the check on the local cpu for us.

Taken from unknown contributor in 2.4

Here's a patch to add an Andrew File System (AFS) driver to the kernel.
Currently it only provides read-only, uncached, non-automounted and
unsecured support.

This adds RxRPC support to Linux for use by the AFS filesystem

Someone adding tests for failed kmalloc's (which is fine in itself)
did so in a way that would leave some PCMCIA data structures in
inconsistent states... and also introduced a fatal bug affecting
PCMCIA memory cards even when there are no kmalloc failures.

This is the RCU core patch from akpm's tree. It has been in his
tree since about 2.5.37-mm1 along with dcache_rcu and so far it has
worked fine. For 2.5, I am hoping that we might get the following
RCU patches included -

1. rt_rcu - ipv4 routecache lookup. Davem agreed to include this patch
   if and when you include RCU core in your tree.

2. dcache_rcu (by Maneesh Soni) - dcache lookup avoiding dcache_lock as
   much as possible. This has been akpm's tree - stable and gives us
   good yield. I have been submitting this to Viro and I will publish
   some more benchmark numbers later to help decide on this.

This RCU core implements RCU APIs, call_rcu() and synchronize_kernel(),
by monitoring a per-CPU quiescent state (idle/user etc.) counter.
call_rcu() queues a callback to be invoked after all the CPUs have
gone through a quiescent state. Queuing is per-CPU and each per-CPU
batch gets a batch number. As batches get their turn, a global
cpu mask is used to keep track of CPUs pending quiescent state.
Checking for quiescent cycle is done by saving the per-CPU
counter at the beginning of the batch and then monitoring it for change
through the local timer interrupt handler.

Adds a raw_phys_apicid array that maps from the mps cpu number
to the apicid - this is needed because the apicids for Summit can be
larger than 32, and thus won't fit into the bitmap. Also adds little wrappers
to map neatly between the two.

Bumps up MAX_APICS for Summit.

Adds detection for summit machines from the MPS tables.
Prints a handy-dandy debug message telling you what kind of twisted
machine the kernel thinks you have.

This one sets up the apic broadcast id (the maximum allowable apic address)
properly for whichever platform. It also abstracts out check_apicid_used,
because that check doesn't work on Summit. Oh, and I bumped up
MAX_IO_APICS, but only for NUMA x86 platforms.

This puts the DFR (desination format register) value into a #define, and
calculates the LDR (logical desitination register) correctly dependant
on platform. Similarly for TARGET_CPUS.

This just adds the config option for summit, and it's Config.help entry,
puts the hooks for the new mach_apic.h subarch file into the right
places, and creates empty shells of the header files.

  - fixed returned structure in ctl_read/write

  - fixed compilation of ioctl32 from David S. Miller

This patch defines a new switch in fs/Config.in -
  CONFIG_NFS_V4:  enables nfsv4 client

Now that all the hooks are in place, this large patch imports all
of the new code for the NFSv4 client.
  nfs4proc.c   - procedure vectors
  nfs4xdr.c    - XDR
  nfs4state.c  - state bookkeeping (very minimal for now)
  nfs4renewd.c - a daemon (implemented as an rpc_task) to keep
                 state from expiring on the server

Note: The RPCSEC_GSS authentication code is not yet included here.
  For the moment we make do with AUTH_UNIX aka. AUTH_SYS.

  Neither is the code to do upcalls to userland in order to do
  uid/gid <-> name mappings. Instead, stubs have been added to
  translate everything to 'nobody:nobody' == '-2:-2'

Define the new NFSv4 data structure for passing user information
from the 'mount' program in nfs4_mount.h.

If CONFIG_NFS_V4 is defined
        Add code to parse the mount structure into the superblock.
        Declare the NFSv4 filesystem to the VFS.

Further cleanups

Separate the static and dynamic filesystem data retrieval calls as per the
NFSv3 spec. This also simplifies things for NFSv4, since many of the
attributes in the fsinfo+fstat combined call are not mandatory to
implement.

Clean up nfs_fill_super().

Separate the parsing of the nfs_mount_data struct and the
initialization + sanity checking of the resulting super_block.
The latter is now performed in the new function nfs_sb_init().

It is just a missing include, fixed thus..
