Ilya Yanok ca9153a3a2 powerpc/44x: Support 16K/64K base page sizes on 44x
This adds support for 16k and 64k page sizes on PowerPC 44x processors.

The PGDIR table is much smaller than a page when using 16k or 64k
pages (512 and 32 bytes respectively) so we allocate the PGDIR with
kzalloc() instead of __get_free_pages().

One PTE table covers rather a large memory area when using 16k or 64k
pages (32MB or 512MB respectively), so we can easily put FIXMAP and
PKMAP in the area covered by one PTE table.

Hollis Blanchard 6ca4f7494b powerpc: Force memory size to be a multiple of PAGE_SIZE
Ensure that total memory size is page-aligned, because otherwise
mark_bootmem() gets upset.

This error case was triggered by using 64 KiB pages in the kernel
while arch/powerpc/boot/4xx.c arbitrarily reduced the amount of memory
by 4096 (to work around a chip bug that affects the last 256 bytes of
physical memory).

Finn Thain 746e8d3b22 m68k: mac baboon interrupt enable/disable
No-one seems to know how to mask individual baboon interrupts, so we just 
mask the umbrella IRQ. This will work as long as only the IDE driver uses 
the baboon chip (it can't deadlock). Use mac_enable_irq/mac_disable_irq 
rather than enable_irq/disable_irq because the latter routines count the 
depth of nested calls which triggers a warning and call trace because 
IRQ_NUBUS_C is enabled twice in a row (once when the baboon handler is 
registered, and once when the IDE IRQ is registered).

Hendrik Brueckner 0946100f56 [S390] s390/setup: set default preferred console device "ttyS"
This patch sets the default console device for s390.

The console= kernel parameter can be still used to switch the preferred
console to some other device. In that case, console messages are also
printed on the default console device (ttyS0).

Heiko Carstens 2b1a61f0a8 [S390] cpu topology: introduce kernel parameter
Introduce a topology=[on|off] kernel parameter which allows to switch
cpu topology on/off. Default will be off, since it looks like that for
some workloards this doesn't behave very well (on s390).

Heiko Carstens c58d92b233 [S390] Remove initial kernel stack backchain initialization.
Early init code clears the backchain of the initial kernel stack frame.
This is not necessary since it is pre initialized with zeros. Plus it
was broken on 64 bit since it cleared only four of eight bytes.

Martin Schwidefsky 2d6cd2a590 [S390] remove warnings with functions ending in BUG
Functions which end in a BUG() statement and skip the return statement
cause compile warnings on s390, e.g.:

mm/bootmem.c: In function 'mark_bootmem':
mm/bootmem.c:321: warning: control reaches end of non-void function

To avoid the warning add an endless loop to the BUG() macro.

Martin Schwidefsky 547e3cec4f [S390] remove ptrace warning on 31 bit.

arch/s390/kernel/ptrace.c: In function 'poke_user':

Getting rid of the dummy variables removes the warnings.
