      lib: crc32: Greatly shrink CRC combining code · 6d514b4e
      由 George Spelvin 提交于 
      There's no need for a full 32x32 matrix, when rows before the last are
just shifted copies of the rows after them.

There's still room for improvement (especially on X86 processors with
CRC32 and PCLMUL instructions), but this is a large step in the
right direction [which is in particular useful for its current user,
namely SCTP checksumming over multiple skb frags[] entries, i.e. in
IPVS balancing when other CRC32 offloads are not available].

The internal primitive is now called crc32_generic_shift and takes one
less argument; the XOR with crc2 is done in inline wrappers.

      tcf_ematch is allocated by kzalloc in function tcf_em_tree_validate(),
so cm_old is always NULL.

====================
Intel Wired LAN Driver Updates 2014-06-20

This series contains updates to i40e and i40evf.

Anjali provides an update to the registers to handle the updates from the
hardware.  Also provides a fix so that we do not try to access the rings
through the qvectors at the time of freeing the qvectors.

Jesse provides a workaround for some older NVM versions where the NVM
was not filling in the GLQF_HKEY register, so made sure that the
critical register is initialized.

Michal provides a fix to reset the head and tail on admin queue
initialization where head and tail are not reset by the hardware.

Neerav adds a helper routine that would wait for the Rx/Tx queue to reach
the enable or disable state that is requested.  Also provides a fix
to the debugfs command "lldp get remote" which was dumping the local
LLDPDU instead of the peer's LLDPDU.  Fixed a bug when all the Tx hang
recovery mechanisms have failed and the driver tries to bring down the
interface in the interrupt context.

Shannon provides a patch to clear the Virtual Ethernet Bridge (VEB) stats
when the PF stats are cleared.  Also cleans the service tasks so that
they do not run while a reset is in progress.

Mitch fixes an issue in i40evf_get_rxfh() where only fifteen registers
were being read instead of all sixteen.

Carolyn provides a change to the RSS configuration to set table size and
write to the hardware to confirm the RSS table size being used.

Kamil makes a change to the admin queue debug prints so that they will not
cause segmentation faults in some of our tool applications.
