Four architectures (arm, mips, sparc, x86) use __vmalloc_area() for
module_init(). Much of the code is duplicated and can be generalized in a
globally accessible function, __vmalloc_node_range().
__vmalloc_node() now calls into __vmalloc_node_range() with a range of
[VMALLOC_START, VMALLOC_END) for functionally equivalent behavior.
Each architecture may then use __vmalloc_node_range() directly to remove
the duplication of code.

Occasionally the system gets into a state where the CMOS clock has gotten
slightly ahead of current time and the periodic update of RTC fails. The
message is a nuisance and repeats spamming the log.
See: http://www.ntp.org/ntpfaq/NTP-s-trbl-spec.htm#Q-LINUX-SET-RTC-MMSS
Rather than just removing the message, make it show only once and reduce
severity since it indicates a normal and non urgent condition.

The device tree code is now in two pieces: some which can be used generically
on any platform which selects CONFIG_OF_FLATTREE, and some early which is used
at boot time on only a few architectures. This patch segregates the early
code so that only those architectures which care about it need compile it.
This also means that some of the requirements in the early code (such as
a cmd_line variable) that most architectures (e.g. X86) don't provide
can be ignored.

I am about to commit:
http://sourceware.org/ml/binutils/2010-10/msg00033.html
that fixes a problem with the LD/SD macro currently implemented by GAS for
the o32 ABI in an inconsistent way. This is best illustrated with a
simple program, which I'm copying here from the message above for easier
reference:
$ cat ld.s
ld $5,32767($4)
ld $5,32768($4)
This gets assebled into the following output:
$ mips-linux-as -32 -mips3 -o ld.o ld.s
$ mips-linux-objdump -d ld.o
ld.o: file format elf32-tradbigmips
Disassembly of section .text:
00000000 <.text>:
0: dc857fff ld a1,32767(a0)

c: 8c258000 lw a1,-32768(at)
10: 8c268004 lw a2,-32764(at)
...
Oops!
The GAS fix makes the macro behave in a consistent way and pairs of LW/SW
instructions to be output as appropriate regardless of the size of the
offset associated with the address used. The machine instruction is still
available, but to reach it macros have to be disabled first. This has a
side effect of requiring the use of a machine-addressable memory operand.
As some platforms require 64-bit operations for accesses to some I/O
registers LD/SD instructions are used in a couple of places in Linux
regardless of the ABI selected. Here's a fix for some pieces of code
affected I've been able to track down. The fix should be backwards
compatible with all supported binutils releases in existence and can be
used as a reference for any other places or off-tree code. The use of the
"R" constraint guarantees a machine-addressable operand.

Consider the following test case:
write_c0_compare(read_c0_count());
Even if the counter doesn't increment during execution, this might not
generate an interrupt until the counter wraps around. The CPU may
perform the comparison each time CP0 COUNT increments, not when CP0
COMPARE is written.
If mips_next_event() is called with a very small delta, and CP0 COUNT
increments during the calculation of "cnt += delta", it is possible
that CP0 COMPARE will be written with the current value of CP0 COUNT.
If this is detected, the function should return -ETIME, to indicate
that the interrupt might not have actually gotten scheduled.

The perf hardware pmu got initialized at various points in the boot,

The problem is that the NMI lockup detector is ran from early_initcall()
and expects the hardware pmu to be present.
Sanitize this by moving all architecture hardware pmu implementations to
initialize at early_initcall() and move the lockup detector to an explicit
initcall right after that.

The TASK_SIZE macro should reflect the size of a user process virtual
address space. Previously for 64-bit kernels, this was not the case.
The immediate cause of pain was in
hugetlbfs/inode.c:hugetlb_get_unmapped_area() where 32-bit processes
trying to mmap a huge page would be served a page with an address
outside of the 32-bit address range. But there are other uses of
TASK_SIZE in the kernel as well that would like an accurate value.
The new definition is nice because it now makes TASK_SIZE and
TASK_SIZE_OF() yield the same value for any given process.
For 32-bit kernels there should be no change, although I did factor
out some code in asm/processor.h that became identical for the 32-bit and
64-bit cases.
__UA_LIMIT is now set to ~((1 << SEGBITS) - 1) for 64-bit kernels.
This should eliminate the possibility of getting a
AddressErrorException in the kernel for addresses that pass the
access_ok() test.
With the patch applied, I can still run o32, n32 and n64 processes,
and have an o32 shell fork/exec both n32 and n64 processes.

BMIPS processor cores are used in 50+ different chipsets spread across
5+ product lines. In many cases the chipsets do not share the same
peripheral register layouts, the same register blocks, the same
interrupt controllers, the same memory maps, or much of anything else.
But, across radically different SoCs that share nothing more than the
same BMIPS CPU, a few things are still mostly constant:
SMP operations
Access to performance counters
DMA cache coherency quirks
Cache and memory bus configuration
So, it makes sense to treat each BMIPS processor type as a generic
"building block," rather than tying it to a specific SoC. This makes it
easier to support a large number of BMIPS-based chipsets without
unnecessary duplication of code, and provides the infrastructure needed
to support BMIPS-proprietary features.
