If either of the two sock_alloc_fd() calls fail, we
forget to update 'err' and thus we'll erroneously
return zero in these cases.

netpoll_poll_lock() synchronizes the ->poll() invocation

sure that NAPI_STATE_SCHED is still set. Otherwise we
get:

TCP Vegas implementation has a bug in the process of disabling
slow-start with gamma parameter. The bug may lead to extreme
unfairness in the presence of early packet loss. See details in:
http://www.cs.caltech.edu/~weixl/technical/ns2linux/known_linux/index.html#vegas
Switch the order of "if (tp->snd_cwnd <= tp->snd_ssthresh)" statement
and "if (diff > gamma)" statement to eliminate the problem.

Instead of using the default timeout of 3 minutes, this uses the timeout
specific to the protocol used for the connection. The 3 minute timeout
seems somewhat arbitrary (though I know it is used other places in the
ipvs code) and when failing over it would be much nicer to use one of
the configured timeout values.

Changes:
1. The baud for spi mmc defined in board file is not used by the old
spi driver. A slower value from spi framework is used instead. In latest
bug fixing, the correct baud is use which is too high for spi MMC card.
2. SPI is enabled only after DMA is started.
3. MMC detection IRQ is set to 55.

As noted by David:
pte_page() is a macro defined as follows;
include/asm-sh/pgtable.h
#define pte_page(x) phys_to_page(pte_val(x)&PTE_PHYS_MASK)
include/asm-sh/page.h
#define phys_to_page(phys) (pfn_to_page(phys >> PAGE_SHIFT))
So as you can see the phys_to_page() macro doesn't wrap the 'phys'
parameter in parentheses so we end up with;
pte_val(x)&PTE_PHYS_MASK >> PAGE_SHIFT
Which is not what we wanted as '>>' has a higher precedence than bitwise
AND. I dug into the git repository and I believe this bug was added with
this commit (104b8deaa5c0144cccfc7d914413ff80c7176af1);

This reverts commit 2e1c49db4c640b35df13889b86b9d62215ade4b6.
First off, testing in Fedora has shown it to cause boot failures,
bisected down by Martin Ebourne, and reported by Dave Jobes. So the
commit will likely be reverted in the 2.6.23 stable kernels.
Secondly, in the 2.6.24 model, x86-64 has now grown support for
SPARSEMEM_VMEMMAP, which disables the relevant code anyway, so while the
bug is not visible any more, it's become invisible due to the code just
being irrelevant and no longer enabled on the only architecture that
this ever affected.
