In a case documented as

  We should never be called with any of these states

6f08b72cdd [PATCH] serial moxa: fix wrong BUG
There is a wrong BUG in mxser_close.

The BUG is triggered when tty->driver_data == NULL, But in fact this is not
a bug, because tty->driver->close is called even when tty->driver->open
fails.

LDD3 tells us to do nothing in such cases.

b9b0332fcf [PATCH] HPET, Maintainers
This patch identifies the HPET Maintainers.  Clemens in taking over as
primary maintainer for the HPET driver.  Clemens has i386 hardware with
HPET and is a better choice than me because of this.  I've shared this
patch with all cc: recipients and there is agreement on ownership.
Hopefully this eliminates future confusion in terms of where HPET
maintenance is owned.

d4b6899678 [PATCH] s390: remove pagex support
Remove pagex pseudo page fault code.  It does not work together with the
system call speedup that makes the complete system call path enabled for
interrupts.  To make pagex and the syscall speedup code work together we would
have to add code to the program check handler to do a critical section cleanup
like the asynchronous interrupt code.  This would make program checks slower.
Not what we want.

Newer versions of z/VM have the improved pfault pseudo page fault interface.
This replaces the old pagex interface and does not have the problem.  So its
better to just rip out the pagex code.

26d89d1eef [PATCH] uml: build host-binaries with the native host arch again
This patch reverts back the changes to HOSTCFLAGS and HOSTLDFLAGS

When we were building complete binaries to get constants (such as ptrace
register layout on stack) from host userspace headers, we needed to make the
arch for building HOST binaries match our one: i.e.  on a 64bit system
compiling 32bit binaries, we compile 32-bit hostprogs and need, say, 32-bit
ncurses.  Now we can revert that - that avoids problem with, say, menuconfig
and ncurses, on a system which can't compile well 32-bit programs.

Network code uses htons() to convert it.  So UML's method to access these

I replaced bytewise copying by memcpy(), maybe even that might be removed, if
ifa->ifa_address/mask may be used immediately.

4f0272415a [PATCH] uml: fix syscall stubs
Jeff Dike noted that the assembly code for syscall stubs is misassembled with
GCC 3.2.3: the values copied in registers weren't preserved between one asm()
and the following one.

So I fixed the thing by rewriting the __asm__ constraints more like unistd.h
ones.

Note: in syscall6 case I had to add one more instruction (i.e.  moving arg6 in
eax and shuffling things around) - it's needed for the function to be valid in
general (we can't load the value from the stack, relative to ebp, because we
change it), but could be avoided since we actually use a constant as param 6.

The only fix would be to turn stub_syscall6 to a macro and use a "i"
constraint for arg6 (i.e., specify it's a constant value).

5f9c3cbcd5 [PATCH] cris: printk() duplicate declaration
printk() already declared in include/linux/kernel.h so squish the
duplication.  Besides, no printk() usage here.  Bye bye.

a4c4af7c8d [PATCH] cpu hoptlug: avoid usage of smp_processor_id() in preemptible code
Replace smp_processor_id() with any_online_cpu(cpu_online_map) in order to
avoid lots of "BUG: using smp_processor_id() in preemptible [00000001]
code:..." messages in case taking a cpu online fails.

All the traces start at the last notifier_call_chain(...) in kernel/cpu.c.
Since we hold the cpu_control semaphore it shouldn't be any problem to access
cpu_online_map.

The reason why cpu_up failed is simply that the cpu that was supposed to be
taken online wasn't even there.  That is because on s390 we never know when a
new cpu comes and therefore cpu_possible_map consists of only ones and doesn't
reflect reality.

77f72b192f [PATCH] i386: LVT entries remaining unmasked on reboot
Excerpt from bugzilla entry

http://bugzilla.kernel.org/show_bug.cgi?id=5518

"i386 version of Reboot-through-BIOS is unsafe: it forgets to mask APIC LVT
interrupts before jumping to a BIOS entry point.  As a result, BIOS ends up
bombarded with interrupts early on boot.  The BIOS does not expect it since
following a "normal" hardware cpu reset, all APIC LVT registers have the
Mask bit (16) set and can't generate interrupts.

For example, the version of Phoenix BIOS used by VMware enables interrupts
for the first time before masking/clearing APIC LVT.  The APIC Timer LVT
register is still set up for a timer interrupt delivery with a high vector
from the previous Linux incarnation (0xef in our case).  The BIOS has not
fully initialized its IDT at this point and the real mode gate for 0xef
remains all zeros.  Vector 0xef dispatches BIOS to address 0:0, BIOS takes
a #GP and eventually hangs.

machine_shutdown() does attempt to shut down APIC before jumping to BIOS,
but it is ineffective"
