When we enable DEBUG_LOCK_ALLOC but do not enable PROVE_LOCKING and or
LOCK_STAT, lock_alloc() and lock_release() turn into nops, even though
we should be doing hlock checking (check=1).
This causes a false warning and a lockdep self-disable.
Rectify this.

Jeff Chua reported that booting a !bigsmp kernel on a 16-way box
hangs silently.
this is a long-standing issue, smp start AP cpu could check the
apic id >=8 etc before trying to start it.
achieve this by moving the def_to_bigsmp check later and skip the
apicid id > 8
[ mingo@elte.hu: clean up the message that is printed. ]

Cyrill Gorcunov observed:

> Could you please add checking for NULL str param?
fix that.
Also, change the name of 'str' into 'arg', to make it more apparent
that this is an optional argument that can be NULL, not a string
parameter that is empty when unset.

This reverts commit 2d04a4a72d7e1519b4838f24bdd4b5d0f3f426dc, which made
it impossible to make the softcursor use the highlight colors.
Yes, the fourth bit should be "blinking", but since we cannot reasonably
blink in fbcon, highlighting it with a bright background is preferable.

Simon Horman reported that gcc-3.4.x crashes when compiling
pgd_prepopulate_pmd() when PREALLOCATED_PMDS == 0 and CONFIG_DEBUG_INFO
is enabled.
Adding an extra check for PREALLOCATED_PMDS == 0 [which is compiled out
by gcc] seems to avoid the problem.

On 32-bit, "apic" is a __setup() param meaning it is parsed rather
late in the game. Make it an early_param() for apic_printk() use
by arch/x86/kernel/mpparse.c.
On 64-bit, it already is an early_param().

commit 11a62a056093a7f25f1595fbd8bd5f93559572b6 turns some formerly
nopped debugging printks in arch/x86/kernel/mppparse.c into regular
ones. The one at the top of smp_scan_config() in particular also
prints on !CONFIG_SMP/CONFIG_X86_LOCAL_APIC kernels and UP machines
without anything resembling MP tables which makes their lowly UP
owners wonder...
Turn the former Dprintk()s into apic_printk()s instead meaning that
their printing is dependent on passing the apic=verbose (or =debug)
command line param.
On 32-bit, "apic" is a __setup() param which isn't early enough
for this code and therefore needs a followup changing it into an
early_param(). On 64-bit, it already is.

So set the CPU active before calling the CPU_ONLINE notifier chain,
there are a handful of notifiers that use set_cpus_allowed().
This fix also solves the problem with x86-microcode. I've sent
alternative patches for microcode, but as this "rely on
set_cpus_allowed_ptr() being workable in cpu-hotplug(CPU_ONLINE, ...)"
assumption seems to be more broad than what we thought, perhaps this fix
should be applied.
With this patch we define that by the moment CPU_ONLINE is being sent,
a 'cpu' is online and ready for tasks to be migrated onto it.

Nice debugging work.
I'd suggest something like the attached (boot tested) patch as the simple
fix for now.
I expect the benefits from the less synchronized, multiple-in-flight-data
global queue will still outweigh the costs of dynamic allocations. But
if worst comes to worst then we just go back to a globally synchronous
one-at-a-time implementation, but that would be pretty sad!

Defer commit 6d299f1b53b84e2665f402d9bcc494800aba6386 to the next release.
Testing of the tip/sched/clock tree revealed a mysql+oltp regression
which bisection eventually traced back to this commit in mainline.
Pertinent test results: Three run sysbench averages, throughput units
in read/write requests/sec.
clients 1 2 4 8 16 32 64
6e0534f 9646 17876 34774 33868 32230 30767 29441
2.6.26.1 9112 17936 34652 33383 31929 30665 29232
6d299f1 9112 14637 28370 33339 32038 30762 29204
Note: subsequent commits hide the majority of this regression until you
apply the clock fixes, at which time it reemerges at full magnitude.
We cannot see anything bad about the change itself so we defer it to the
next release until this problem is fully analysed.

In order to align the coding styles of ip_vs_zero_stats() and
its child-function ip_vs_zero_estimator(), clear ip_vs_stats
members explicitlty rather than doing a limited memset().
This was chosen over modifying ip_vs_zero_estimator() to use
memset() as it is more robust against changes in members
in the relevant structures. memset() would be prefered if
all members of the structure were to be cleared.

It's a global variable and automatically initialized to zero. And now we can
also initialize the lock at compile time.

There's no reason for dynamically allocating an estimator object for every
stats object. Directly embed an estimator object into every stats object and
switch to using the kernel-provided list implementation. This makes the code
much simpler and faster, as we do not need to traverse the list of all
estimators to find the one belonging to a stats object. There's no need to use
an rwlock, as we only have one reader. Also reorder the members of the
estimator structure slightly to avoid padding overhead. This can't be done
with the stats object as the members are currently copied to our user space
object via memcpy() and changing it would break ABI.

Allow user to pass parameters on kernel command line to override
default size for physically contiguous memory buffers. The default
VPU buffer size is too small for VGA harware encoding, but instead
of just bumping up the number we allow the user to override the
default size using the command line. Supports SuperH Mobile hardware
blocks such as VEU, VPU and CEU.

The i2c layer got changed while the migor_ts driver was in the input

Presently we oops in mm/hugetlb.c:1325, which is the order == 0 test in
hugetlb_add_hstate() called at initialization time. So, disable 64kB
huge pages when we're using a 64kB PAGE_SIZE. On most parts this will
force the default to be 1MB huge pages.

That worked with 2.6.26, and these are far less undefined references
than in the cases where libgcc was missing.
