Andrew Morton c773633916 deprecate smbfs in favour of cifs
smbfs is a bit buggy and has no maintainer.  Change it to shout at the user on
the first five mount attempts - tell them to switch to CIFS.

Come December we'll mark it BROKEN and see what happens.

Hugh Dickins 8cb2a7c1e9 stop c_p_a corrupting the pds
When change_page_attr splits a large page on x86_32 (without PAE), it is
currently corrupting every process's page directory: fix that by removing
the thinko which passes down a physical instead of a virtual address.

Stefano Brivio 8dd0100ce9 b43legacy: fix DMA slot resource leakage
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.

This patch by Michael Buesch has been ported to b43legacy.

Stefano Brivio 9eca9a8e81 b43legacy: drop packets we are not able to encrypt
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.

Stefano Brivio ada50731c0 b43legacy: fix suspend/resume
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.

This patch by Michael Buesch has been ported to b43legacy.

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

NETDEV_TX_BUSY instead. This was discussed on the netdev list before,

Jeff Dike f87ea91d98 uml: redo the calculation of NR_syscalls
Redo the calculation of NR_syscalls since that disappeared from i386 and
use a similar mechanism on x86_64.

We now figure out the size of the system call table in arch code and stick
that in syscall_table_size.  arch/um/kernel/skas/syscall.c defines
NR_syscalls in terms of that since its the only thing that needs to know
how many system calls there are.

The old mechananism that was used on x86_64 is gone.

arch/um/include/sysdep-i386/syscalls.h got some formatting since I was
looking at it.

Downgrade one of the MAC validity checks.  If it's one that could be possibly
assigned to a physical NIC, then nothing will break.  So, emit a warning in
this case, but keep the requested MAC.

Karol Swietlicki cc0be0fb3f uml: fix infinite mconsole loop
This patch takes care of a problem with the stopping code.

The function inside the while condition returns 0 to signify a problem.  A
problem could be for example a bad command or a bad version of the mconsole
client.  A bad command would terminate the stopping loop and resume the
kernel.  This is a problem.

A better solution is to make the loop infinite and don't leave it until we are
explicitly told to.
