Patch from Nicolas Pitre

It appears that the EF_ARM_SOFT_FLOAT is a reserved bit with the new
ARM EABI.  Since EABI is said to not support FPA (FPA emulation being
the reason why we'd want to disable iWMMXt access) we now test for any
EABI version as well to turn on iWMMXt access.

Patch from Nicolas Pitre

This implements TLS support in the most efficient way for all ARM
processors in use today.  The trick is to define a specific address in
kernel area that is made readable from user space to hold the TLS
pointer so it is highly efficient to retrieve it with no overhead.
Since the kernel already maps a page at 0xffff0000 to hold the exception
vectors, we can use the top of that page for storing the TLS ptr at
0xffff0ffc. This address has the advantage of fitting optimally with the
ARM load addressing mode as follows:
	mov	rd, #0xffff0fff
	ldr	rd, [rd, #-3]
Considering load scheduling, this means 2 cycles to retrieve the TLS
value which is even faster than a coprocessor access.  Even gcc
generates the above assembly when given:
	void *tls = *((void **)0xffff0ffc);
This is fine to make the vector page readable from user space since it
contains nothing that could compromize security and doesn't require an
extra memory page to be allocated.
On SMP (which should be ARMv6 and above only) the special reg for
TLS will be available.  Since ARMv6 binaries are most likely to use
strex/ldrex insns instead of swp to implement user space atomic
primitives, those ARMv6 binaries won't execute on pre ARMv6 processors
anyway.  So the abscence of a tls reg is a non issue for them already.
Also on SMP targets, since the hivec page can't be relied upon to get
the TLS value, we'll have the kernel emulate access to it through the
data abort vector for backward compatibility with pre ARMv6 binaries.
Otherwise, non SMP ARMv6 kernels will support both methods
simultaneously.
So the decision to use hivec or tlsreg could depend on whether given
library is optimized for ARMv6+ or not. And since ARM SMP devices are
still far from becoming mainstream we can safely go with the hivec (and
hivec emulation on SMP) for the time being.

The adrsvc macro was used to allow the entry-* files to be built on
ARM32 and ARM26 processors.  Since we no longer support ARM26 CPUs,
eliminate this macro.

This is the third of 4 patches which factor out common code in
the ARM exception entry assembly code, aiming towards a reduction
in the size of the changes required here for SMP support.  These
patches are low impact, and will be merged over the coarse of the

This patch addresses the code handling exception entry from user

The special case for the Sharp LH processors is unnecessary.  A macro
override makes it cleaner and concentrates the change where it ought
to be.  The default in include/asm-arm/numnodes.h means that only
platforms that care to change the default need to do anything.

If the transmit buffer of the e100 overflowed, then the system would hang.
This was caused because the e100 driver would stop the queue, and
netpoll_send_pkt in netpoll.c would then loop forever.  This is because the
e100 net_poll would never start the queue again after the transmits have
completed.

For those that use the e100 and netconsole, all you need to do is a sysreq
't' to lock up the system.
