This patch should fix TOC handling for cdroms that can not play audio.  It
extends commit af744e32 ("cdrom: don't
check CDC_PLAY_AUDIO in cdrom_count_tracks()") with a safety check and
non-audio ioctls support.

Since CDC_PLAY_AUDIO flag was used not only to check ability to play audio
but also to ensure that audio_ioctl was not NULL, all TOC-related
operations had to use it.

As far as I understand, now audio_ioctl is never NULL, so a sanity check
during device registration should be sufficient.

It was tested on Optiarc AD7203A device, that has no ability to play
audio.

commit c3965bd1

Date:   Wed May 14 08:15:34 2008 -0700

    x86 boot: proper use of ARRAY_SIZE instead of repeated E820MAX constant

caused these new warnings during a normal build:

In file included from linux-2.6/arch/x86/boot/memory.c:17:
linux-2.6/include/linux/log2.h: In function '__ilog2_u32':
linux-2.6/include/linux/log2.h:34: warning: implicit declaration of function 'fls'

linux-2.6/include/linux/log2.h:63: warning: implicit declaration of function 'fls_long'

I tried to fix them in log2.h, but it's difficult because the real mode
environment is completely different from a normal kernel environment. Instead
define an own ARRAY_SIZE macro in boot.h, similar to the other private
macros there.

Quoting Mike Travis in "x86: cleanup early per cpu variables/accesses v4"
(23ca4bba):

    The DEFINE macro defines the per_cpu variable as well as the early
    map and pointer.  It also initializes the per_cpu variable and map
    elements to "_initvalue".  The early_* macros provide access to
    the initial map (usually setup during system init) and the early
    pointer.  This pointer is initialized to point to the early map
    but is then NULL'ed when the actual per_cpu areas are setup.  After
    that the per_cpu variable is the correct access to the variable.

As these variables are NULL'ed before __init sections are dropped
(in setup_per_cpu_maps), they can be safely annotated as __ref.

This change silences following section mismatch warnings:

x86_64 add/sub atomic ops does not seems to accept integer values bigger
than 32 bits as immediates. Intel's add/sub documentation specifies they
have to be passed as registers.

The only operations in the x86-64 architecture which accept arbitrary
64-bit immediates is "movq" to any register; similarly, the only
operation which accept arbitrary 64-bit displacement is "movabs" to or
from al/ax/eax/rax.

http://gcc.gnu.org/onlinedocs/gcc-4.3.0/gcc/Machine-Constraints.html

states :

e
    32-bit signed integer constant, or a symbolic reference known to fit
    that range (for immediate operands in sign-extending x86-64
    instructions).
Z
    32-bit unsigned integer constant, or a symbolic reference known to
    fit that range (for immediate operands in zero-extending x86-64
    instructions).

Since add/sub does sign extension, using the "e" constraint seems appropriate.

It applies to 2.6.27-rc, 2.6.26, 2.6.25...

The intent of "flush_tlbs" is to invalidate all TLB entries by doing a
TLB invalidate instruction for all pages in the address range 0 to
0x00400000.  A loop counter is set up at the high value and
decremented by page size.  However, the loop is only done once as the
sense of the conditional branch at the loop end does not match the
setup/decrement.  This fixes it to do the whole range by correcting
the branch condition.
