(Blah about unused variables).
This code still won't be used, as its still not tested/debugged properly
on a Nehemiah.

We got half multipliers horribly wrong, which made us think we could
clock the CPU much higher than we actually could.

Now that longhaul=1 matches more than 1 CPU, this broke.

These CPUs are actually only longhaul v1 compliant.
This was catastrophic, as the MSRs moved between v1 and v2.
There was also massive confusion in the documentation regarding Ezra.
It's not another variant, so 'v2' never existed.
Renamed v3 (Powersaver) to v2 as a result of this.

This code is from ancient history when TCP did not used SKB cloning.

cause NULL pointer references in /proc.

Moreover, it's questionable whether the whole thing makes sense at all. 
Per-thread state is good.

net/sunrpc/clnt.c does not compile if RPC_DEBUG is not enabled, due to
the fact that tk_pid is protected by RPC_DEBUG (which in turn depends on
CONFIG_SYSCTL).

The printk's that use it don't actually need to print it out at all,
the rpc_task tag isn't really interesting here.

Acked by Trond Myklebust.

The Zoran driver doesn't include <asm/io.h> and thus won't compile
on architectures where that doesn't get implicitly included through
some other path.

Add the proper includes.

This is the latest iteration of the workaround for the Athlon/Opteron
prefetch erratum.  Sometimes the CPU would incorrectly report an
exception on prefetch.

This supercedes the previous dumb workaround of checking for AMD CPUs in
prefetch().  That one bloated the kernel by several KB and lead to lots
of unnecessary checks in hot paths. 

Also this one handles user space faults too, so the kernel can
effectively isolte the user space from caring about this errata.

Instead it handles it in the slow path of the exception handler (the
check is only done when the kernel would normally trigger seg fault or
crash anyways)

All the serious criticisms to the previous patches have been addressed. 
It checks segment bases now, handles vm86 mode and avoids deadlocks when
the prefetch exception happened inside mmap_sem.

This includes review and fixes from Jamie Lokier and Andrew Morton.
Opcode decoder based on code from Richard Brunner.

This fixes some problems with timing calculations (primarily for ia64)
and adds an operation to send panic strings to the IPMI event log on a
panic.

Since 2.6.0-test6, ftape can't be configured as a built-in driver.
test6 changed ftape-init.c to call ftape_proc_destroy() also in
the non-MODULE case; however, ftape_proc_destroy() is only defined
when the driver is built as a module. The result is a linkage error.

This fixes this by deleting the #if MODULE around ftape_proc_destroy()'s
definition.

on lots of PCI-only setups that have no ISA anywhere.

 - add vbi device handling for dvb-c cards with analog module
 - fix error handling upon device initialization
 - fix DD1_INIT handling of DVB-C w/ analog module installed.  (Jon
   Burgess)

 - fixed some return values in device attach functions
 - allow private data to be associated with frontend devices here, too
 - misc bugfixes and performance improvements (endianess, function split up)

 - applied latest changes by Juergen Peitz (great work!)
  o as a workaround for the lockup problem the data valid signal is
    checked after every channel switch.  If it is not set FEC parameters
    are set again.
  o disabled autoprobing if FEC settings are known (from sp887x). 
  o added support for FE_READ_UNCORRECTED_BLOCKS (from sp887x).
  o added support for FE_SLEEP (from sp887x).
  o bit error rate is now not only read from register 0xC07 but also
    from 0xC08 (from sp887x). 
  o I2C feedthrough to the tuner is now only enabled when needed (from
    sp887x).
  o Added FE_CAN_QAM_AUTO and FE_CAN_HIERARCHY_AUTO to
    dvb_frontend_info.
  o Removed obsolete setting of default frontend parameters in
    sp8870_init.
  o Removed obsolete module parameter 'loadcode' because changes in the
    saa7146 driver made firmware loading very fast.

 - simplify and sanitize add/del handling for dvb net devices

 - allow private data to be associated with dvb frontend devices
   (Andreas Oberritter)
 - fixed fe_count countint in nxt6000 frontend driver (Andreas
   Oberritter)

 - add some debug and safety checks for video/vbi capture buffer
   handling
 - add new flag SAA7146_USE_PORT_B_FOR_VBI, so we can distinguish on
   which video port to apply the vbi workaround
 - add del_timer(...) for vbi capture queue and vbi_read timers,
   prevents oopses on vbi usage

 - replace alps_bsrv2 driver by generic ves1893 & ves1993 driver
   (Andreas Oberritter)

Fix another 64bit bug, this time in the trident frame buffer driver

When storing the ioremap_nocache() return in a integer the variable must be
long not int.

Paul McKenney convinced me that there's no *guarantee* that all archs
will refuse the speculate the atomic ops above the state test, eg:

CPU0 (stopref_set_state)		CPU1 (stopref)

 atomic_set(&ack, 0);			if (state == XXX)
 wmb();						atomic_inc(&ack);
 state = XXX;

Certainly Alpha needs a rmb() inside stopref to guarantee it sees
the same ordering.

The range that the iptables limit extension can specify depends on HZ.
This means that rules which worked i386 2.4 (100 HZ) won't work on
2.6.

The solution is to adjust the precision based on the HZ value (keeping
the range of possible values the same).  For extra geek cred, this is
done by calculating a power-of-two constant below the maximum
multiplication factor, which gcc then turns into a simple shift.

  Compile errors in the pcmcia/tcic driver if PCMCIA_DEBUG is defined.
  Looks like simple debug code bitrot, this fixes it.

At the moment the aty128fb and matroxfb frame buffer drivers don't
compile on PPC.  In both cases the error is pretty trivial.  This
patch is the minimum change to fix the problems.

The _IOR() type problem fix in aty128fb.c depends on the fact that the
size of a pointer is the same as "size_t", so we don't have to use
_IOR_BAD() to keep the ioctl number the same.

Noted by Al Viro: if no handler exists (and we have IRQ_INPROGRESS set
because of an earlier irq that got through), synchronize_irq() will
end up waiting forever.
