      The driver always ends a read with a STOP condition which breaks · 9f2e7ffc
      Joakim Tjernlund authored 
      subsequent I2C reads/writes in the same transaction as these expect to do
a repeated START(ReSTART).

This will also help I2C multimaster as the bus will not be released after
the first read, but when the whole transaction ends.

      Alexander Strakh authored 
        91         usb_make_path(dev, cam->input_physname, sizeof(cam->input_physname));

After this line we use strncat:

  92         strncat(cam->input_physname, "/input0", sizeof(cam->input_physname));

where sizeof(cam->input_physname) returns length of cam->input_phisname
without length for null-symbol.  But this parameter must be - "maximum
numbers of bytes to copy", i.e.:
sizeof(cam->input_physname)-strlen(cam->input_physname)-1.

In this case, after call to usb_make_path the similar drivers use strlcat.

Like in: drivers/hid/usbhid/hid-core.c:
1152         usb_make_path(dev, hid->phys, sizeof(hid->phys));
1153         strlcat(hid->phys, "/input", sizeof(hid->phys));

Found by Linux Driver Verification Project.

Use strlcat instead of strncat.

      The Collaborative Memory Manager (CMM) module allocates individual pages · 4991cbe3

      over time that are not migratable.  On a long running system this can
severely impact the ability to find enough pages to support a hotplug
memory remove operation.

This patch adds a memory isolation notifier and a memory hotplug notifier.
The memory isolation notifier will return the number of pages found in
the range specified.  This is used to determine if all of the used pages
in a pageblock are owned by the balloon (or other entities in the notifier
chain).  The hotplug notifier will free pages in the range which is to be
removed.  The priority of this hotplug notifier is low so that it will be
called near last, this helps avoids removing loaned pages in operations
that fail due to other handlers.

CMM activity will be halted when hotplug remove operations are active and
resume activity after a delay period to allow the hypervisor time to
adjust.

      Memory balloon drivers can allocate a large amount of memory which is not · b141d0ae
      Robert Jennings authored 
      movable but could be freed to accomodate memory hotplug remove.

Prior to calling the memory hotplug notifier chain the memory in the
pageblock is isolated.  Currently, if the migrate type is not
MIGRATE_MOVABLE the isolation will not proceed, causing the memory removal
for that page range to fail.

Rather than failing pageblock isolation if the migrateteype is not
MIGRATE_MOVABLE, this patch checks if all of the pages in the pageblock,
and not on the LRU, are owned by a registered balloon driver (or other
entity) using a notifier chain.  If all of the non-movable pages are owned
by a balloon, they can be freed later through the memory notifier chain
and the range can still be isolated in set_migratetype_isolate().

      acpi_processor_power_init and fixes a section mismatch warning.

 We were warned by the following warning:

 LD      drivers/acpi/processor.o
WARNING: drivers/acpi/processor.o(.text+0x1829): Section mismatch in
reference from the function acpi_processor_add() to the function
.cpuinit.text:acpi_processor_power_init()
The function acpi_processor_add() references
the function __cpuinit acpi_processor_power_init().
This is often because acpi_processor_add lacks a __cpuinit
annotation or the annotation of acpi_processor_power_init is wrong.

      Presently acpi-cpufreq will perform the MSR read on the first CPU in the · 13f92591

      mask.  That's inefficient if that CPU differs from the current CPU. 
Because we have to perform a cross-CPU call, but we could have run the
rdmsr on the current CPU.

So switch to using the new smp_call_function_any(), which will perform the
call on the current CPU if that CPU is present in the mask (it is).
