This adds markers two important points in the spufs code and a new
module (sputrace.ko) that allows reading these out through a proc file.
Long-term I'd rather see something like lttng extended to use the spufs
instrumentation, but for now I think this is a good enough quick
solution. We'll probably want to add various addition event in addition
to that ones I have already.

This patch converts cpmac to the new Fixed PHY infrastructure, though it
doesn't fix all the problems with that driver. I didn't even bother to
test this patch to compile, because cpmac driver is broken in several ways:
1. This driver won't compile by itself because lack of its header describing
platform data;
2. It assumes that fixed PHYs should be created by the ethernet driver.
It is wrong assumption: fixed PHYs creation is platform code authority,
driver must blindly accept bus_id and phy_id platform data variables
instead.
Also, it seem that that driver doesn't have actual in-tree users, so
nothing to fix further.
The main purpose of that patch is to get rid of the following Kconfig
warning:
scripts/kconfig/conf -s arch/powerpc/Kconfig
drivers/net/Kconfig:1713:warning: 'select' used by config symbol
'CPMAC' refers to undefined symbol 'FIXED_MII_100_FDX'

The ext3 root inode was treated specially with respect
to in-inode extended attributes, for reasons detailed
in the removed comment below. The first mkfs-created
inodes would not get extra_i_size or the EXT3_STATE_XATTR
flag set in ext3_read_inode, which disallowed reading or
setting in-inode EAs on the root.
However, in ext4, ext4_mark_inode_dirty calls
ext4_expand_extra_isize for all inodes; once this is done
EAs may be placed in the root ext4 inode body.
But for reasons above, it won't be found after a reboot.
testcase:
setfattr -n user.name -v value mntpt/
setfattr -n user.name2 -v value2 mntpt/
umount mntpt/; remount mntpt/
getfattr -d mntpt/
name2/value2 has gone missing; debugfs shows it in the
inode body, but it is not found there by getattr.
The following fixes it up; newer mkfs appears to properly
zero the inodes, so this workaround isn't needed for ext4.

Teach the debug logging macro to differentiate between log levels based on the
type of debug level enabled specifically instead of a threshold-based one.
Thus, convert tape->debug_level to a bitmask that is written to over /proc.
Also,
- cleanup and simplify the debug macro thus removing a lot of code lines,
- get rid of unused debug levels,
- adjust the loglevel at several places where it was simply missing (e.g.
idetape_chrdev_open())
- move the tape ptr initialization up in idetape_chrdev_open() so that we can
use it in the debug_log macro earlier in the function.

The commit 139ddfcab5 ("ide: move handling of
I/O resources out of ide_probe_port()") changed the ordering of hwif->noprobe
check vs ide_hwif_request_regions() call (so that we now reserve I/O regions
before checking for hwif->noprobe). However ide-generic host driver depended
on hwif->noprobe to be set for skipping probing of empty ide_hwifs[] slots.
Fix it by passing only indexes of non-empty slots to ide_device_add_all()
from ide_generic_init().
