2009-01-09[S390] hvc_iucv: Special handling of IUCV HVC devicesHendrik Brueckner
This patch introduces special handling of the IUCV HVC console device. If the first IUCV HVC terminal is used as (preferred) Linux console, and needs some special handling for hangup. The hvc_iucv_private structure contains a flag to indicate whether a IUCV HVC device is used as a console. A terminal acting as "console" behaves different if a tty hangup occurs: If the iucv communication path is severed, a tty hangup is not triggered (because the HVC layer does not notify its back-end in that case). Instead, the console session is left unchanged and the IUCV HVC device is reset to allow re-connects. Note: Any output between the disconnect and a re-connect is discarded.

If no communication path to a IUCV HVC terminal exist, any data written to the terminal is discarded.

2009-01-06random: don't try to look at entropy_count outside the lockMatt Mackall
As a non-atomic value, it's only safe to look at entropy_count when the pool lock is held, so we move the BUG_ON inside the lock for correctness. Also remove the spurious comment. It's ok for entropy_count to temporarily exceed POOLBITS so long as it's left in a consistent state when the lock is released. This is a more correct, simple, and idiomatic fix for the bug in 8b76f46a2db. I've left the reorderings introduced by that patch in place as they're harmless, even though they don't properly deal with potential atomicity issues.
