bh1721: delay first read after light sensor enable

Light sensor was delaying first time read to
poll delay milli seconds. This fix changes the
first time read delay to 50 milli seconds.
bh1721: set poll_delay to DELAY_LOWBOUND when new delay < DELAY_LOWBOUND

If a delay of 0 or some low value is passed from any apps,
then system can lock up.

KVM: VMX: fix halt emulation while emulating invalid guest sate

commit 8d76c49e9ffeee839bc0b7a3278a23f99101263e upstream.

The invalid guest state emulation loop does not check halt_request
which causes 100% cpu loop while guest is in halt and in invalid
state, but more serious issue is that this leaves halt_request set, so
random instruction emulated by vm86 #GP exit can be interpreted
as halt which causes guest hang. Fix both problems by handling
halt_request in emulation loop.

ARM: OMAP: RX-51: change probe order of touchscreen and panel SPI devices

commit e65f131a14726e5f1b880a528271a52428e5b3a5 upstream.

Commit 9fdca9df (spi: omap2-mcspi: convert to module_platform_driver)
broke the SPI display/panel driver probe on RX-51/N900. The exact cause is
not fully understood, but it seems to be related to the probe order. SPI
communication to the panel driver (spi1.2) fails unless the touchscreen
(spi1.0) has been probed/initialized before. When the omap2-mcspi driver
was converted to a platform driver, it resulted in that the devices are
probed immediately after the board registers them in the order they are
listed in the board file.

Fix the issue by moving the touchscreen before the panel in the SPI
device list.

The patch fixes the following failure:

[    1.260955] acx565akm spi1.2: invalid display ID
[    1.265899] panel-acx565akm display0: acx_panel_probe panel detect error
[    1.273071] omapdss CORE error: driver probe failed: -19

ACPICA: Fix possible buffer overflow during a field unit read operation

commit 61388f9e5d93053cf399a356414f31f9b4814c6d upstream.

Can only happen under these conditions: 1) The DSDT version is 1,
meaning integers are 32-bits.  2) The field is between 33 and 64
bits long.

It applies cleanly back to ACPICA 20100806+ (Linux v2.6.37+).

xen/vcpu/pvhvm: Fix vcpu hotplugging hanging.

commit 7f1fc268c47491fd5e63548f6415fc8604e13003 upstream.

If a user did:

	echo 0 > /sys/devices/system/cpu/cpu1/online
	echo 1 > /sys/devices/system/cpu/cpu1/online

we would (this a build with DEBUG enabled) get to:
smpboot: ++++++++++++++++++++=_---CPU UP  1
.. snip..
smpboot: Stack at about ffff880074c0ff44
smpboot: CPU1: has booted.

and hang. The RCU mechanism would kick in an try to IPI the CPU1
but the IPIs (and all other interrupts) would never arrive at the
CPU1. At first glance at least. A bit digging in the hypervisor
trace shows that (using xenanalyze):

[vla] d4v1 vec 243 injecting
   0.043163027 --|x d4v1 intr_window vec 243 src 5(vector) intr f3
]  0.043163639 --|x d4v1 vmentry cycles 1468
]  0.043164913 --|x d4v1 vmexit exit_reason PENDING_INTERRUPT eip ffffffff81673254
   0.043164913 --|x d4v1 inj_virq vec 243  real
  [vla] d4v1 vec 243 injecting
   0.043164913 --|x d4v1 intr_window vec 243 src 5(vector) intr f3

]  0.043166800 --|x d4v1 vmexit exit_reason PENDING_INTERRUPT eip ffffffff81673254
   0.043166800 --|x d4v1 inj_virq vec 243  real
  [vla] d4v1 vec 243 injecting

there is a pending event (subsequent debugging shows it is the IPI
from the VCPU0 when smpboot.c on VCPU1 has done
"set_cpu_online(smp_processor_id(), true)") and the guest VCPU1 is
interrupted with the callback IPI (0xf3 aka 243) which ends up calling
__xen_evtchn_do_upcall.

The __xen_evtchn_do_upcall seems to do *something* but not acknowledge
the pending events. And the moment the guest does a 'cli' (that is the
ffffffff81673254 in the log above) the hypervisor is invoked again to
inject the IPI (0xf3) to tell the guest it has pending interrupts.
This repeats itself forever.

The culprit was the per_cpu(xen_vcpu, cpu) pointer. At the bootup
we set each per_cpu(xen_vcpu, cpu) to point to the
shared_info->vcpu_info[vcpu] but later on use the VCPUOP_register_vcpu_info
to register per-CPU  structures (xen_vcpu_setup).
This is used to allow events for more than 32 VCPUs and for performance
optimizations reasons.

When the user performs the VCPU hotplug we end up calling the
the xen_vcpu_setup once more. We make the hypercall which returns
-EINVAL as it does not allow multiple registration calls (and
already has re-assigned where the events are being set). We pick
the fallback case and set per_cpu(xen_vcpu, cpu) to point to the
shared_info->vcpu_info[vcpu] (which is a good fallback during bootup).
However the hypervisor is still setting events in the register
per-cpu structure (per_cpu(xen_vcpu_info, cpu)).

As such when the events are set by the hypervisor (such as timer one),
and when we iterate in __xen_evtchn_do_upcall we end up reading stale
events from the shared_info->vcpu_info[vcpu] instead of the
per_cpu(xen_vcpu_info, cpu) structures. Hence we never acknowledge the
events that the hypervisor has set and the hypervisor keeps on reminding
us to ack the events which we never do.

The fix is simple. Don't on the second time when xen_vcpu_setup is
called over-write the per_cpu(xen_vcpu, cpu) if it points to
per_cpu(xen_vcpu_info).
