Several counters behave differently on 82598 causing them to display
incorrect values. Adjust the accounting so the reported numbers
make sense and do not double count or represent the wrong item.

Changes in other networking paths uncovered a bug in the xircom_cb
driver which made the kernel spew lots of the following error messages:
BUG eth1 code -5 qlen 0
It turned out that the driver returned -EIO when there was no
descriptor available for sending packets. It should return
NETDEV_TX_BUSY instead. This was discussed on the netdev list before,
see http://thread.gmane.org/gmane.linux.network/84603 .

The Yukon FE chip has a ram buffer therefore it needs the alignment
restriction and hang check workarounds.
Therefore:
* Autodetect the prescence/absence of ram buffer
* Rename the flag value to reflect this
* Use it consistently (ie don't reread register)

This fixes four resource leakages.
In any error path we must deallocate the DMA frame slots we
previously allocated by request_slot().
This is done by storing the ring pointers before doing any ring
allocation and restoring the old pointers in case of an error.

We must drop any packets we are not able to encrypt.
We must not send them unencrypted or with an all-zero-key (which
basically is the same as unencrypted, from a security point of view).
This might only trigger shortly after resume before mac80211 reassociated
and reconfigured the keys.
It is safe to drop these packets, as the association they belong to
is not guaranteed anymore anyway.
This is a security fix in the sense that it prevents information leakage.

This patch makes suspend/resume work with the b43legacy driver.
We must not overwrite the MAC addresses in the init function, as this
would also overwrite the MAC on resume. With an all-zero MAC the device
firmware is not able to ACK any received packets anymore.
Fix this by moving the initializion stuff that must be done on init but
not on resume to the start function.
Also zero out filter_flags to make sure we don't have some flags
from a previous instance for a tiny timeframe until mac80211 reconfigures
them.

Changeset fde6a3c82d67f592eb587be4d12222b0ae6d4321 ("iommu sg merging:
sparc64: make iommu respect the segment size limits") broke sparc64
because whilst it added the segment limiting code to the first pass of
SG mapping (in prepare_sg()) it did not add matching code to the
second pass handling (in fill_sg())
As a result the two passes disagree where the segment boundaries
should be, resulting in OOPSes, DMA corruption, and corrupted
superblocks.

We cannot start transaction in ext3_direct_IO() and just let it last during
the whole write because dio_get_page() acquires mmap_sem which ranks above
transaction start (e.g. because we have dependency chain
mmap_sem->PageLock->journal_start, or because we update atime while holding
mmap_sem) and thus deadlocks could happen. We solve the problem by
starting a transaction separately for each ext3_get_block() call.
We *could* have a problem that we allocate a block and before its data are
written out the machine crashes and thus we expose stale data. But that
does not happen because for hole-filling generic code falls back to
buffered writes and for file extension, we add inode to orphan list and
thus in case of crash, journal replay will truncate inode back to the
original size.

The argument chain for ext[234]_find_goal() is not used. This patch removes
it and fixes comment as well.

The comment in ext[234]_new_blocks() describes about "i". But there is no
local variable called "i" in that scope. I guess it has been renamed to
group_no.

ext3 file system was by default ignoring errors and continuing. This is
not a good default as continuing on error could lead to file system
corruption. Change the default to mark the file system readonly. Debian
and ubuntu already does this as the default in their fstab.

This fixes some instances where we were continuing after calling
ext3_error. ext3_error calls panic only if errors=panic mount option is
set. So we need to make sure we return correctly after ext3_error call

None of the callers of this function does actually take the BKL as far as I
can see. So remove the comment refering to the BKL.
