The xfrm flowcache size is limited by the flowcache limit
(4096 * number of online cpus) and the xfrm garbage collector
threshold (2 * 32768), whatever is reached first. This means
that we can hit the garbage collector limit only on systems
with more than 16 cpus. On such systems we simply refuse
new allocations if we reach the limit, so new flows are dropped.
On syslems with 16 or less cpus, we hit the flowcache limit.
In this case, we shrink the flow cache instead of refusing new
flows.
We increase the xfrm garbage collector threshold to INT_MAX
to get the same behaviour, independent of the number of cpus.
The xfrm garbage collector threshold can still be set below
the flowcache limit to reduce the memory usage of the flowcache.

The I2C core always reports the MODALIAS uevent as "i2c:<modalias>"
regardless of the mechanism that was used to register the device
(i.e: OF or board code) and the table that is used later to match
the driver with the device (i.e: I2C id table or OF match table).
So drivers needs to export the I2C id table and this be built into
the module or udev won't have the necessary information to autoload
the needed driver module when the device is added.
But this means that OF-only drivers needs to have both OF and I2C id
tables that have to be kept in sync and also the dev node compatible
manufacturer prefix is stripped when reporting the MODALIAS. Which can
lead to issues if two vendors use the same I2C device name for example.
To avoid the above, the I2C core behavior may be changed in the future
to not require an SPI device table for OF-only drivers and report the
OF module alias. So, it's better to also export the OF table even when
is unused now to prevent breaking module loading when the core changes.

Some GIC revisions require an individual configuration to esp. add
workarounds for HW bugs. This patch implements generic code to parse
the hw revision provided by an IIDR register value and runs specific
code if hw matches. A function is added that reads the IIDR registers
for ITS (GITS_IIDR) and then goes through a list of init functions to
be called for specific versions. Same could be done for GICV3
(GICD_IIDR), but there are no users yet for it.
The patch is needed to implement workarounds for HW errata in Cavium's
ThunderX GICV3 ITS.

This patch is basically a prerequisite for a follow-on patch that adds
errata code for Cavium ThunderX. It moves the calculation of the
number of id entries to the beginning of the function close to other
setup values that are needed to allocate the its table. Now we have a
central location to modify the setup parameters and the errata code
can be implemented in a single block.

This patch implements Cavium ThunderX erratum 23154.
The gicv3 of ThunderX requires a modified version for reading the IAR
status to ensure data synchronization. Since this is in the fast-path
and called with each interrupt, runtime patching is used using jump
label patching for smallest overhead (no-op). This is the same
technique as used for tracepoints.

There were several bugs here.
1) The done label was in the wrong place so we didn't copy any
information out when there was no command given.
2) We were using PAGE_SIZE as the size of the buffer instead of
"PAGE_SIZE - pos".
3) snprintf() returns the number of characters that would have been
printed if there were enough space. If there was not enough space
(and we had fixed the memory corruption bug #2) then it would result
in an information leak when we do simple_read_from_buffer(). I've
changed it to use scnprintf() instead.
I also removed the initialization at the start of the function, because
I thought it made the code a little more clear.

When p2p device interface gets deleted by deinitialising discovery
it will result in an event which removes the interface, but that is
also done by delete p2p interface code. This results in race
condition which sometimes results in lockup/crash. With this patch
the delete device interface will wait for the event (with timeout)
removing the possible race condition. Also on the stop device call
from cfg80211 the deinitialisation of the discovery device should
