bzip2/lzma: make internal initramfs compression configurable
Impact: Avoids silent environment dependency
Make builtin initramfs compression an explicit configurable. The
previous version would pick a compression based on the binaries which
were installed on the system, which could lead to unexpected results.
It is now explicitly configured, and not having the appropriate
binaries installed on the build host is simply an error.

init: make initrd/initramfs decompression failure a KERN_EMERG event
Impact: More consistent behaviour, avoid policy in the kernel
Upgrade/downgrade initrd/initramfs decompression failure from
inconsistently a panic or a KERN_ALERT message to a KERN_EMERG event.
It is, however, possible do design a system which can recover from
this (using the kernel builtin code and/or the internal initramfs),
which means this is policy, not a technical necessity.
A good way to handle this would be to have a panic-level=X option, to
force a panic on a printk above a certain level. That is a separate
patch, however.

x86: only scan the root bus in early PCI quirks
We found a situation on Linus' machine that the Nvidia timer quirk hit on
a Intel chipset system. The problem is that the system has a fancy Nvidia
card with an own PCI bridge, and the early-quirks code looking for any
NVidia bridge triggered on it incorrectly. This didn't lead a boot
failure by luck, but the timer routing code selecting the wrong timer
first and some ugly messages. It might lead to real problems on other
systems.
I checked all the devices which are currently checked for by early_quirks
and it turns out they are all located in the root bus zero.
So change the early-quirks loop to only scan bus 0. This incidently also
saves quite some unnecessary scanning work, because early_quirks doesn't
go through all the non root busses.
The graphics card is not on bus 0, so it is not matched anymore.

One of the devices in the array has partitions, and mdadm always
deletes partitions before putting a whole-device in an array (as it
can cause confusion). The next IO to that device locks the machine.
I don't really understand exactly why it locks up, but it happens in
disk_map_sector_rcu(). This patch fixes it.
Which is due to a missing clear of the (now) stale partition lookup

Normally this marking happens in btrfs_alloc_free_block, which also does

[S390] hvc_iucv: Special handling of IUCV HVC devices
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.
