low_cpu_die is called from the CPU hotplug code on 32-bit powermacs,

In calculating stolen time, we were trying to actually account for time
spent in the hypervisor.  We don't really have enough information to do
that accurately, so don't try.  Instead, we now calculate stolen time as
time that the current cpu thread is not actually dispatching instructions.
On chips without a PURR, we cannot do this, so stolen time will always
be zero.  On chips with a PURR, this is merely the difference between
the elapsed PURR values and the elapsed TB values.

This gives us much more sane vaules from tools such as mpstat, even if
they are still a bit strange e.g. 2 busy threads on one cpu will both
appear to have 50% user time and 50% stolen time while 1 busy thread on
a cpu will look like 100% user on one of them and 100% idle on the other.

The current implementation uses a sequence of a cacheflush and a copy.

Aside this fixes a performance hog rendering access to /proc/cmdline very
slow and resulting in a enough cache stalls for the 34K AP/SP programming

CCISS was producing warnings about shifts being greater than the size of
the type and pointers being of incompatible type.  Turns out this is
because it's calling do_div on a 32-bit quantity.  Upon further
investigation, the sector_t total_size is being assigned to an int, and
then we're calling do_div on that int.  Obviously, sector_div is called for
here, and I took the chance to refactor the code a little.

Mistyped an ifdef CONFIG_CPUSETS - fixed.

I doubt that anyone ever noticed.  The impact of this typo was
that if someone:
 1) was using MPOL_BIND to force off node allocations
 2) while using cpusets to constrain memory placement
 3) when that cpuset was migrating that jobs memory
 4) while the tasks in that job were actively forking
then there was a rare chance that future allocations using
that MPOL_BIND policy would be node local, not off node.

The zonelist may contain zones of nodes that have not been bootstrapped and
we will oops if we try to allocate from those zones.  So check if the node
information for the slab and the node have been setup before attempting an

Usually we will not encounter this situation since the slab bootstrap code
avoids falling back before we have setup the respective nodes but we seem

The change from __setup() to module_param_named() requires users to prefix
the option with "generic.".

This patch re-adds the __setup() additionally to the module_param_named().

Usually it would make sense getting rid of such an obsolete __setup() at
some time, but considering that drivers/ide/ is slowly approaching a RIP
status it's already implicitely scheduled for removal.

Commits 881a8c12 and

only one way; it no longer oopses/crashes, despite hotplug is not solved

Whenever pci_find_device -> pci_get_device change is performed, also
pci_dev_get and pci_dev_put should be in most cases called to properly
handle hotplug.  This patch does exactly this thing -- increase refcount

Since the ++ is used as post-increment, the increment is not included
in free_index, and so the added line effectively reverts the
increment.  The produced_index side has an analagous bug.
