s390/3270: correct size detection with the read-partition command

2014-07-16T08:48:10+00:00

The size detection for 3270 terminals with the read-partition command is
broken. The raw3270_reset_device_cb function clears the init_data array,
but if raw3270_writesf_readpart has been called the read-partition command
is queued which needs the init_data array. In this case the size detection
will fail and the invalid command does funny things to the terminal.

s390: avoid format strings leaking into names

This makes sure format strings can't accidentally leak into kernel
interface names.

s390/sclp_vt220: Enable ASCII console per default

2014-06-10T08:48:29+00:00

When you want to use the HMC's ASCII console as console device for
a z/VM guest you have to specify console=ttyS1 on the kernel command
line. But it won't work until you specify conmode=sclp as well.

This behavior is inconsistent with the use of the ASCII console as
TTY device which works on z/VM without the need to specify a conmode.

Fix this inconsistency by removing the check for conmode=sclp in the
ASCII console registration function.

Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm into next

2014-06-04T15:47:12+00:00

Pull KVM updates from Paolo Bonzini:
 "At over 200 commits, covering almost all supported architectures, this
  was a pretty active cycle for KVM.  Changes include:

   - a lot of s390 changes: optimizations, support for migration, GDB
     support and more

   - ARM changes are pretty small: support for the PSCI 0.2 hypercall
     interface on both the guest and the host (the latter acked by
     Catalin)

   - initial POWER8 and little-endian host support

   - support for running u-boot on embedded POWER targets

   - pretty large changes to MIPS too, completing the userspace
     interface and improving the handling of virtualized timer hardware

   - for x86, a larger set of changes is scheduled for 3.17.  Still, we
     have a few emulator bugfixes and support for running nested
     fully-virtualized Xen guests (para-virtualized Xen guests have
     always worked).  And some optimizations too.

  The only missing architecture here is ia64.  It's not a coincidence
  that support for KVM on ia64 is scheduled for removal in 3.17"

s390/dump: Remove CONFIG_ZFCPDUMP

2014-05-20T06:58:43+00:00

Currently there are two s390 kernel dump config options "CONFIG_ZFCPDUMP"
and "CONFIG_CRASH_DUMP". In order to keep things simple and because the
"CONFIG_ZFCPDUMP" option already has a dependency to "CONFIG_CRASH_DUMP"
remove the CONFIG_ZFCPDUMP option.

s390/mm: Convert bootmem to memblock

2014-05-20T06:58:40+00:00

The original bootmem allocator is getting replaced by memblock. To
cover the needs of the s390 kdump implementation the physical memory
list is used.
With this patch the bootmem allocator and its bitmaps are completely
removed from s390.
