Now that the SH-4 page clear/copy ops are generic, they can be used for
all platforms with CONFIG_MMU=y. SH-5 remains the odd one out, but it too
will gradually be converted over to using this interface.
SH-3 platforms which do not contain aliases will see no impact from this
change, while aliasing SH-3 platforms will get the same interface as
SH-4.
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
This wires up clear_user_highpage() on SH-4 and subsequently converts the
SH7705 32kB cache mode over to using it. Now that the SH-4 implementation
handles all of the dcache purging directly in the aliasing case, there is
no need to do this in the default clear_page() implementation.

The ezLCD+101 board (to which an favr-32 is fitted) has a long,
unshielded, nasty lead between the touch panel and the ads7843 touch
controller. In order to get satisfactory response then, we need to
employ every noise-reduction trick in the driver's arsenal. After
extensive fiddling I've found some good settings:
1) We keep vref on all the time to dramatically reduce settling times
(at the cost of a tiny increase in power consumption).
2) Despite 1 the settling time is still non-zero. 500uS is plenty of
time for the signals to settle
3) Despite 1 and 2 there's still a little bit of noise around. By
setting a pen recheck delay we make the panel feel less touchy and
twitchy.
Someone with more time and patience myself might be able to tune this
numbers further but these settings are now perfectly acceptable for
normal use.
Tested on ezLCD+101 though should only improve response on other ezLCD+/
favr-32 boards too.

o Use ':=' for assignmnet so we do not re-evaluate for each use
o Use $(shell echo xxx) to remove ""
o Replaced CFLAGS_KERNEL with KBUILD_CFLAGS
The settings are equally relevant for modules and the linked kernel
o Dropped LDFLAGS_BLOB - it is no longer used
o Refactored assignmnets to libs-y and core-y
o Use MMU for the MMU specific extension. "MMUEXT" was hurting my eyes

commit 6321e3ed2a caused
the full bmv_count's worth of getbmapx structures to get
allocated; telling it to do MAXEXTNUM was a bit insane,
resulting in ENOMEM every time.
Chop it down to something reasonable, the number of slots
in the caller's input buffer. If this is too large the
caller may get ENOMEM but the reason should not be a
mystery, and they can try again with something smaller.
We add 1 to the value because in the normal getbmap
world, bmv_count includes the header and xfs_getbmap does:
nex = bmv->bmv_count - 1;
if (nex <= 0)
return XFS_ERROR(EINVAL);

It is not exactly pretty to leave the receiver enabled but we
