Abstract the code sequence for adding a signal handler's sa_mask to
current->blocked because the sequence is identical for all architectures.
Furthermore, in the past some architectures actually got this code wrong,
so introduce a wrapper that all architectures can use.

Unlike other architectures, sparc currently has no SA_NODEFER definition
but only the older SA_NOMASK.  Since SA_NOMASK is the historical name for
SA_NODEFER, add SA_NODEFER and copy what other architectures do by making
SA_NOMASK a synonym for SA_NODEFER.

Randomization of PIE load address is hard coded in binfmt_elf.c for X86
and ARM.  Create a new Kconfig variable
(CONFIG_ARCH_BINFMT_ELF_RANDOMIZE_PIE) for this and use it instead.  Thus
architecture specific policy is pushed out of the generic binfmt_elf.c and
into the architecture Kconfig files.

X86 and ARM Kconfigs are modified to select the new variable so there is
no change in behavior.  A follow on patch will select it for MIPS too.

As described in e6fa16ab ("signal: sigprocmask() should do
retarget_shared_pending()") the modification of current->blocked is
incorrect as we need to check whether the signal we're about to block
is pending in the shared queue.

Some SoCs have a timer block enable controlled through the DSCR registers.
There is a problem in the timer64 driver initialization where the code
accesses a timer register to get the divisor used to calculate timer clock
rate. If the timer block has not been enabled when this register read takes
place, an exception is generated. This patch makes sure that the timer block
is enabled before accessing the registers.

This factors out the AMD native MMCONFIG discovery so we can use it
outside amd_bus.c.

amd_bus.c reads AMD MSRs so it can remove the MMCONFIG area from the
PCI resources.  We may also need the MMCONFIG information to work
around BIOS defects in the ACPI MCFG table.
