In commit 9aa3283595 (ehea/ibm*: Move the
IBM drivers) the IBM_NEW_EMAC* were renames to IBM_EMAC*
The conversion was incomplete so that even if the driver was added to
the .config it wasn't built, but there were no errors). In this commit
we also update the various defconfigs that use EMAC to use the new
Kconfig symbol, and explicitly add the NET_VENDOR_IBM guard.
We do not explicitly select the Kconfig dependencies, as this would force
EMAC on. Doing it in the defconfig allows more flexibility.
Tested on a canyondlands board.

Instead of setting up a match interrupt for 'current_time + delta'
on ->set_next_event(), program timer 0 to count down from 'delta - 1'
and trigger an interrupt when it reaches zero.

Currently, arch-mmp/time.c uses timer 0 both as a clocksource timer
and as a clockevent timer, the latter by setting up a comparator
interrupt to match on 'current_time + delta'. This is problematic
if delta is small enough, as that can lead to 'current_time + delta'
already being in the past when comparator setup has finished, leading
to the requested event not triggering.
As there is also a silicon issue that requires stopping a timer's
counter while writing to one of its match registers, we'll switch to
using two separate timers -- timer 0 as clockevent timer, which we'll
start and stop on every invocation of ->set_next_event(), and timer 1
as clocksource timer, which will be free-running.
This first patch enables timer 1 on boot, so that we can use it as
clocksource timer.

vsyscall=emulate (default): Vsyscalls are emulated by instruction

that it's marked NX. This way programs that make assumptions about

POSIX specifies how siginfo_t should be populated for alignment

Currently, it's possible to set the kernel to ignore alignment
faults when changing the alignment fault handling mode at runtime
via /proc/sys/alignment, even though this is undesirable on ARMv6
and above, where it can result in infinite spins where an un-fixed-
up instruction repeatedly faults.
In addition, the kernel clobbers any alignment mode specified on
the command-line if running on ARMv6 or above.
This patch factors out the necessary safety check into a couple of
new helper functions, and checks and modifies the fault handling
mode as appropriate on boot and on writes to /proc/cpu/alignment.
Prior to ARMv6, the behaviour is unchanged.
For ARMv6 and above, the behaviour changes as follows:
* Attempting to ignore faults on ARMv6 results in the mode being
forced to UM_FIXUP instead. A warning is printed if this
happened as a result of a write to /proc/cpu/alignment. The
user's UM_WARN bit (if present) is still honoured.
* An alignment= argument from the kernel command-line is now
honoured, except that the kernel will modify the specified mode
as described above. This is allows modes such as UM_SIGNAL and
UM_WARN to be active immediately from boot, which is useful for
debugging purposes.

which has 2 problems - an off by one error so that we do one less word

and poison too much. On a platform with HAVE_TCM=y but nothing in the

later updates to the *_proc_info structures missed this file.
