Currently, we set PSPR just before entering sleep mode. However,
some platforms have different requirements for setting PSPR in
order to properly wake up.
Set PSPR earlier in the suspend cycle so that platforms can
change the setting by using a sysdev driver instead.

Properly hook the I2C driver into the PM code; the previous fix for
this (ece5f7b3c4) worked around the
platform where I2C is required to be available early during resume.
It has been found to be sufficient to use the early resume hook for
this function, so the original hack can die. Leave the hack in
place for the PIO transfer handler though.

When EEH detects an i/o error it resets the device thus it cannot be accessed.
In this case the driver needs to unload its interface only with OS, kernel and
network stack but not with the device.
After successful recovery, the driver can load normally.

When running a 31-bit ptrace, on either an s390 or s390x kernel,
reads and writes into a padding area in struct user_regs_struct32
will result in a kernel panic.
This is also known as CVE-2008-1514.
Test case available here:
http://sources.redhat.com/cgi-bin/cvsweb.cgi/~checkout~/tests/ptrace-tests/tests/user-area-padding.c?cvsroot=systemtap
Steps to reproduce:
1) wget the above
2) gcc -o user-area-padding-31bit user-area-padding.c -Wall -ggdb2 -D_GNU_SOURCE -m31
3) ./user-area-padding-31bit
<panic>
Test status
-----------
Without patch, both s390 and s390x kernels panic. With patch, the test case,
as well as the gdb testsuite, pass without incident, padding area reads
returning zero, writes ignored.
Nb: original version returned -EINVAL on write attempts, which broke the
gdb test and made the test case slightly unhappy, Jan Kratochvil suggested
the change to return 0 on write attempts.
