I was looking at this out of interest, but I'm in no way familiar with
the code.
Looks to me that the error handling code in mac80211_hwsim is awkward.
Which leads to it calling ieee80211_unregister_hw even when
ieee80211_register_hw failed.
The function has a for loop where it generates all simulated radios.
when something fails, the error handling will call mac80211_hwsim_free
which frees all simulated radios who's pointer isn't zero. However the
information stored is insufficient to determine whether or not the call
to ieee80211_register_hw succeeded or not for a specific radio. The
included patch makes init_mac80211_hwsim clean up the current simulated
radio, and then calls into mac80211_hwsim_free to clean up all the
radios that did succeed.
This however doesn't explain why the rate control registration failed..
build tested this, but had some problems reproducing the original
problem.

Initially netfilter has had 64bit counters for conntrack-based accounting, but
it was changed in 2.6.14 to save memory. Unfortunately in-kernel 64bit counters are
still required, for example for "connbytes" extension. However, 64bit counters
waste a lot of memory and it was not possible to enable/disable it runtime.
This patch:
- reimplements accounting with respect to the extension infrastructure,
- makes one global version of seq_print_acct() instead of two seq_print_counters(),
- makes it possible to enable it at boot time (for CONFIG_SYSCTL/CONFIG_SYSFS=n),
- makes it possible to enable/disable it at runtime by sysctl or sysfs,
- extends counters from 32bit to 64bit,
- renames ip_conntrack_counter -> nf_conn_counter,
- enables accounting code unconditionally (no longer depends on CONFIG_NF_CT_ACCT),
- set initial accounting enable state based on CONFIG_NF_CT_ACCT
- removes buggy IPCT_COUNTER_FILLING event handling.
If accounting is enabled newly created connections get additional acct extend.
Old connections are not changed as it is not possible to add a ct_extend area
to confirmed conntrack. Accounting is performed for all connections with
acct extend regardless of a current state of "net.netfilter.nf_conntrack_acct".

This is a trivial patch against the hdlcdrv module that fixes its CRC

Based upon a bug report by Alexey Dobriyan, the patch is
also tested by him and confirmed to fix the problem.
Packet flow during link state events should not be done by
waking and stopping the TX queue anyways, that is handled
transparently by netif_carrier_{on,off}().
So, remove the netif_{wake,stop}_queue() calls in the link
check code, and add the necessary netif_start_queue() call
to atl1_up().

Explicitly check for memory allocation failures, and return status to
indicate that we could not collect data due to errors.
This lets the driver have a far more predictable failure mode on ENOMEM in
that codepath: it will refuse to load. This is far better than trying to

Add a read/write rfkill interface to the bluetooth radio switch on the
bluetooth submodule, and one for the wireless wan radio switch to the wan
submodule.
Since rfkill does care for when a switch changes state, use WLSW
notifications to also check if the WWAN or Bluetooth switches did not
change state (due to them being slaves of WLSW in firmware/hardware, but
that reality not being always properly exported by the thinkpad firmware).

On ThinkPads where the WLSW switch exists, the firmware or the hardware
ANDs the WLSW state with the device-specific switches (WWAN, Bluetooth).
It is downright impossible to enable WWAN or Bluetooth when WLSW is
blocking the radios.
This reality does not necessarily carry over to the WWAN and Bluetooth
firmware interfaces, though... so the state thinkpad-acpi was reporting
could be incorrect.
Tie the three switches in the driver so that we keep their state sane.
When WLSL is off, force the other switches to off as well.
