ARM: convert printk(KERN_* to pr_*

Convert many (but not all) printk(KERN_* to pr_* to simplify the code.
We take the opportunity to join some printk lines together so we don't
split the message across several lines, and we also add a few levels
to some messages which were previously missing them.

ARM: 8026/1: Fix emulation of multiply accumulate instructions

The emulation for single and double precision multiply accumulate
instructions correctly normalised any denormal values in the operand
registers, but failed to normalise the destination (accumulator)
register.

This fixes https://bugzilla.kernel.org/show_bug.cgi?id=70501

[PATCH] arm build fail: vfpsingle.c

It looks like Zach Brown's patch pr_debug-check-pr_debug-arguments
worked as inteded. That is, it doesn't "allow completely incorrect code
to build." :).

The arm build fails with the following message:
CC arch/arm/vfp/vfpsingle.o
arch/arm/vfp/vfpsingle.c: In function `__vfp_single_normaliseround':
arch/arm/vfp/vfpsingle.c:201: error: `func' undeclared (first use in
this function)
arch/arm/vfp/vfpsingle.c:201: error: (Each undeclared identifier is
reported only once

make[1]: *** [arch/arm/vfp/vfpsingle.o] Error 1
make: *** [arch/arm/vfp] Error 2

The following patch fixes the issue by using func only when DEBUG is
defined.

[ARM] Cleanups for 4cc9bd2eaa1063c68341c1c00e66660adcfdf254

- Document the meaning for OP_SCALAR, OP_SD and add OP_DD.
- Formatting cleanups
- Remove now redundant code for making compare instructions
operate on scalar values.

[ARM] 3789/4: Fix VFP emulation to ignore VECITR for scalar instruction

VECITR in Floating-Point Exception register indicates the number of
remaining short vector iterations after a potential exception was
detected.

In case of exception caused by scalar instructions, VECITR is NOT updated.
Therefore emulation for VFP must ignore VECITR field
and treat "veclen" as zero when recognizing scalar instructing.

[ARM] 3750/3: Fix double VFP emulation for EABI kernels

Patch from Daniel Jacobowitz

vfp_put_double didn't work in a CONFIG_AEABI kernel. By swapping
the arguments, we arrange for them to be in the same place regardless
of ABI. I made the same change to vfp_put_float for consistency.

[ARM] 3758/1: Preserve signalling NaNs in conversion

Patch from Daniel Jacobowitz

The fcvtds and fcvtsd instructions were generating a qnan bit pattern

[ARM] 3749/3: Correct VFP single/double conversion emulation

Patch from Daniel Jacobowitz

The fcvtsd/fcvtds emulation was left behind when the numbering of double
precision registers was changed from 0-30 to 0-15. Both conversion
instructions were writing their results to the wrong register. Also,
the conversion instructions should stop after the first element even
if a vector length is specified.

[ARM] vfp: fix leak of VFP_NAN_FLAG into FPSCR

The VFP code can leak VFP_NAN_FLAG into the FPSCR. It doesn't correspond
to any real FPSCR bit (and overlaps one of the exception flags).

[ARM] 3473/1: Use numbers 0-15 for the VFP double registers

Patch from Catalin Marinas

This patch changes the double registers numbering to 0-15 from even 0-30,
in preparation for future VFP extensions. It also fixes the VFP_REG_ZERO
bug (value 16 actually represents the 8th double register with the original
numbering).

The original mcrr/mrrc on CP10 were generating FMRRS/FMSRR instead of
FMRRD/FMDRR. The patch changes to CP11 for the correct instructions.

Linux-2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
