In short, current eagerfpu changes return 0 for interrupted_kernel_fpu_idle() and the in_interrupt() thinks it is in the interrupt context because of the local_bh_disable(). Thus resulting in the WARN_ON(). Remove the local_bh_disable/enable() calls around the existing local_irq_disable/enable() calls. local_irq_disable/enable() already disables the BH. [ If there are any other legitimate users calling kernel_fpu_begin() from the process context but with BH disabled, then we can look into fixing the irq_fpu_usable() in future. ] Signed-off-by: Suresh Siddha <suresh.b.siddha@intel.com> Cc: Tim Chen <tim.c.chen@linux.intel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

If the hardware accelerator goes offline for any reason (dynamic disable, migration, etc...), this driver will use LZO as a software failover for all future compression requests. For decompression requests, the 842 hardware driver contains a software implementation of the 842 decompressor to support the decompression of data that was compressed before the accelerator went offline.

This benefits processes that have very many mostly idle sockets, which is quite common. From Eric Dumazet. 10) Use up to 32K for page fragment allocations, with fallbacks to smaller sizes when higher order page allocations fail. Benefits are a) less segments for driver to process b) less calls to page allocator c) less waste of space. From Eric Dumazet. 11) Allow GRO to be used on GRE tunnels, from Eric Dumazet. 12) VXLAN device driver, one way to handle VLAN issues such as the limitation of 4096 VLAN IDs yet still have some level of isolation.

* / crypto: authenc - Fix crash with zero-length assoc dataHerbert Xu2012-09-111-2/+2
|/ | | | | | | | | | | | | | | | | | The authenc code doesn't deal with zero-length associated data correctly and ends up constructing a zero-length sg entry which causes a crash when it's fed into the crypto system. This patch fixes this by avoiding the code-path that triggers the SG construction if we have no associated data. This isn't the most optimal fix as it means that we'll end up using the fallback code-path even when we could still execute the digest function. However, this isn't a big deal as nobody but the test path would supply zero-length associated data.
