Maciej W. Rozycki 392a0408fd i2c-sibyte: SWARM I2C board initialization
The standard rtc-m41t80.c driver cannot be used with the SWARM as it is,
because the board does not provide setup information for the I2C core.  
As a result the bus and the address to probe for the M41T80 chip is not
known.

 Here is a set of changes that fix the problem:

1. swarm-i2c.c -- SWARM I2C board setup, currently for the M41T80 chip on 
   the bus #1 only (there is a MAX6654 temperature sensor on the bus #0 
   which may be added in the future if we have a driver for that chip).

2. The i2c-sibyte.c BCM1250A SMBus controller driver now registers its 
   buses as numbered so that board setup is correctly applied.

H. Peter Anvin 3bf2e77453 x86, suspend, acpi: enter Big Real Mode
The explanation for recent video BIOS suspend quirk failures is that
the VESA BIOS expects to be entered in Big Real Mode (*.limit = 0xffffffff)
instead of ordinary Real Mode (*.limit = 0xffff).

This patch changes the segment descriptors to Big Real Mode instead.

The segment descriptor registers (what Intel calls "segment cache") is
always active.  The only thing that changes based on CR0.PE is how it is
*loaded* and the interpretation of the CS flags.

The segment descriptor registers contain of the following sub-registers:
selector (the "visible" part), base, limit and flags.  In protected mode
or long mode, they are loaded from descriptors (or fs.base or gs.base can
be manipulated directly in long mode.)  In real mode, the only thing
changed by a segment register load is the selector and the base, where the
base <- selector << 4.  In particular, *the limit and the flags are not
changed*.

As far as the handling of the CS flags: a code segment cannot be writable
in protected mode, whereas it is "just another segment" in real mode, so
there is some kind of quirk that kicks in for this when CR0.PE <- 0.  I'm
not sure if this is accomplished by actually changing the cs.flags register
or just changing the interpretation; it might be something that is
CPU-specific.  In particular, the Transmeta CPUs had an explicit "CS is
writable if you're in real mode" override, so even if you had loaded CS
with an execute-only segment it'd be writable (but not readable!) on return
to real mode.  I'm not at all sure if that is how other CPUs behave.

Heiko Carstens 1d030370f0 [S390] Remove P390 support.
Most likely it is broken anyway because of the changes in memory
detection. Since we can't test it and there are probably better ways
that using a P390 card, remove support for it.

Move memory detection code to own file and also simplify it.
Also add an interface which can be called at any time to get the
current memory layout. This interface is needed by our kernel
internal system dumper.

Julia Lawall 402a3998ba [S390] arch/s390: Eliminate NULL test and memset after alloc_bootmem
As noted by Akinobu Mita in patch b1fceac2b9,
alloc_bootmem and related functions never return NULL and always return a
zeroed region of memory.  Thus a NULL test or memset after calls to these
functions is unnecessary.

This was fixed using the following semantic patch.

Hendrik Brueckner a0443fbb46 [S390] Extra Kernel Parameters via VMPARM
Now it is possible to specify additional kernel parameters on the IPL
command line using the IPL PARM option.
If the Linux system is already running, the new reipl sysfs attribute
'parm' can be used to change kernel parameters for the next reboot.
Examples:
  IPL    C PARM dasd=1234 root=/dev/dasda1
  IPL 1234 PARM savesys=mylnxnss
  echo "init=/bin/bash" > /sys/firmware/reipl/ccw/parm

This patch adds a driver for subchannels of type chsc.

- obtain information about the machine's I/O configuration
- dynamically change the machine's I/O configuration via
  asynchronous chsc commands

Heiko Carstens 761cdf6aac [S390] initrd vs bss section clearing.
In case the initrd is located within the bss section it will be
overwritten when the section is cleared. To prevent this just move
the initrd right behind the bss section if it starts within the
section.
The current code already moves the initrd if the bootmem allocator
bitmap would overwrite it. With this patch we should be safe against
initrd corruptions.
