* crypto: talitos - handle descriptor not found in error pathKim Phillips2011-10-211-8/+10
| | | | | | | | | | | | | | | | | The CDPR (Current Descriptor Pointer Register) can be unreliable when trying to locate an offending descriptor. Handle that case by (a) not OOPSing, and (b) reverting to the machine internal copy of the descriptor header in order to report the correct execution unit error. Note: printing all execution units' ISRs is not effective because it results in an internal time out (ITO) error and the EU resetting its ISR value (at least when specifying an invalid key length on an SEC 2.2/MPC8313E).

* crypto: padlock-aes - Make module loading even quieter when hardware is missingJonathan Nieder2011-08-031-3/+1
| | | | | | | | | | | | | | | | | | When loading aes via the module alias, a padlock module failing to load due to missing hardware is not particularly notable. With v2.6.27-rc1~1107^2~14 (crypto: padlock - Make module loading quieter when hardware isn't available, 2008-07-03), the padlock-aes module suppresses the relevant messages when the "quiet" flag is in use; but better to suppress this particular message completely, since the administrator can already distinguish such errors by the absence of a message indicating initialization failing or succeeding. This avoids occasional messages in syslog of the form padlock_aes: VIA PadLock not detected.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the regulator supply implementation is somewhat complex and fragile as it doesn't look like standard consumers but is instead a parallel implementation. This causes issues with locking and reference counting. Move the implementation over to using standard consumers to address this. Rather than only notifying the supply on the first enable/disable we do so every time the regulator is enabled or disabled, simplifying locking as we don't need to hold a lock on the consumer we are about to enable.

This means that the delays which the enables implement can all run in parallel, though it does mean that the order in which the supplies come on may be unstable. For super bonus fun points if any of the regulators are shared between multiple supplies on the same device (as is rather likely) then this will test our locking. Note that in this case we only delay once for each physical regulator so the threads shouldn't block each other while delaying. It'd be even nicer if we could coalesce writes to a shared enable registers in PMICs but that's definitely future work, and it may also be useful and is certainly more achievable to optimise out the parallelism if none of the regulators implement ramp delays.

In this case, we can probe for how many channels there are and don't need the platform data. As memcpy requests don't need channel private data to hold peripheral info, allow private data to be NULL in this case.
