When CONFIG_PM is selected, the VFP code does not have any handler
installed to deal with either saving the VFP state of the current
task, nor does it do anything to try and restore the VFP after a
resume.
On resume, the VFP will have been reset and the co-processor access
control registers are in an indeterminate state (very probably the
CP10 and CP11 the VFP uses will have been disabled by the ARM core
reset). When this happens, resume will break as soon as it tries to
unfreeze the tasks and restart scheduling.
Add a sys device to allow us to hook the suspend call to save the
current thread state if the thread is using VFP and a resume hook
which restores the CP10/CP11 access and ensures the VFP is disabled
so that the lazy swapping will take place on next access.

The commit 39263db7986bf15c753f6847699107bdf5a2e318 added
a default <mach/io.h> implementation which is shared if
needed between all the s3c implementations. Remove the
s3c24a0 version which is the same as this.

Add the fourth UART definition for the S3C2443, and at the

Fix the usage of CONFIG_SERIAL_SAMSUNG_UARTS in several places
in the kernel where it had been missed. This finishes fixing a
long standing issue where S3C2443 and S3C64XX could not use the
4th UART

Remove the gpio mux setup function from i.MX framebuffer driver.
This function is platform specific and thus should be done by

of this driver we do not break anything.
