Make use of the EXTABLE_FAULT exception table entries to write
a kernel copy routine that doesn't crash the system if it
encounters a machine check. Prime use case for this is to copy
from large arrays of non-volatile memory used as storage.

We have to use an unrolled copy loop for now because current
hardware implementations treat a machine check in "rep mov"
as fatal. When that is fixed we can simplify.

Return type is a "bool". True means that we copied OK, false means
that it didn't.

For Scalable MCA enabled processors, errors are listed per IP block. And
since it is not required for an IP to map to a particular bank, we need
to use HWID and McaType values from the MCx_IPID register to figure out
which IP a given bank represents.

We also have a new bit (TCC) in the MCx_STATUS register to indicate Task
context is corrupt.

Add logic here to decode errors from all known IP blocks for Fam17h
Model 00-0fh and to print TCC errors.

IPv4 interprets a negative return value from a protocol handler as a
request to redispatch to a new protocol.  In contrast, IPv6 interprets a
negative value as an error, and interprets a positive value as a request
for redispatch.

UDP for IPv6 was unaware of this difference.  Change __udp6_lib_rcv() to
return a positive value for redispatch.  Note that the socket's
encap_rcv hook still needs to return a negative value to request
dispatch, and in the case of IPv6 packets, adjust IP6CB(skb)->nhoff to
identify the byte containing the next protocol.

vmxnet3 has a function vmxnet3_parse_and_copy_hdr which, among other operations,
uses pskb_may_pull to linearize the header portion of an skb.  That operation
eventually uses local_bh_disable/enable to ensure that it doesn't race with the
drivers bottom half handler.  Unfortunately, vmxnet3 preforms this
parse_and_copy operation with a spinlock held and interrupts disabled.  This
causes us to run afoul of the WARN_ON_ONCE(irqs_disabled()) warning in
local_bh_enable, resulting in this:

Fix it by splitting vmxnet3_parse_and_copy_hdr into two functions:

vmxnet3_parse_hdr, which sets up the internal/on stack ctx datastructure, and
pulls the skb (both of which can be done without holding the spinlock with irqs
disabled

and

vmxnet3_copy_header, which just copies the skb to the tx ring under the lock
safely.

The descriptor queues for sending (SDQs) and receiving (RDQs) packets
are managed by two counters - producer and consumer - which are both
16-bit in size. A queue is considered full when the difference between
the two equals the queue's maximum number of descriptors.

However, if the producer counter overflows, then it's possible for the
full queue check to fail, as it doesn't take the overflow into account.
In such a case, descriptors already passed to the device - but for which
a completion has yet to be posted - will be overwritten, thereby causing
undefined behavior. The above can be achieved under heavy load (~30
netperf instances).

Fix that by casting the subtraction result to u16, preventing it from
being treated as a signed integer.

the LAG, we should always decrement the bridge's reference count, as it's

  CPUs, and another to fix the set_memory_xx() permission functions to
  deal with zero sizes correctly"

  with the feature bits.

  It decodes a few extra fields in two different messages and reports
  EIO when they are used (not yet supported)"

     pseudo op which is not supported by the LLVM assembler.
   - Fix invalid initialization on S-cache-less systems.
   - Fix possible information leak from the kernel stack for SIGFPE.
   - Fix handling of copy_{from,to}_user() return value in KVM
   - Fix the last instance of irq_to_gpio() which now was causing build
     errors"
