Commit 51bc085d ("PCI: Improve host drivers compile test coverage")
added configuration options to allow PCI host controller drivers to be
compile tested on all architectures.

Some host controller drivers (eg PCIE_ALTERA) config entries select the
PCI_DOMAINS config option to enable PCI domains management in the kernel.
Now that host controller drivers can be compiled on all architectures, this
triggers build regressions on arches that do not implement the PCI_DOMAINS
required API (ie pci_domain_nr()):

  drivers/ata/pata_ali.c: In function 'ali_init_chipset':
  drivers/ata/pata_ali.c:469:38: error: implicit declaration of function 'pci_domain_nr'; did you mean 'pci_iomap_wc'?

Furthemore, some software configurations (ie Jailhouse) require a
PCI_DOMAINS enabled kernel to configure multiple host controllers without
having an explicit dependency on the ARM platform on which they run.

Make PCI_DOMAINS a visible configuration option on ARM so that software
configurations that need it can manually select it and move the PCI_DOMAINS
selection from PCI controllers configuration file to ARM sub-arch config
entries that currently require it, fixing the issue.

If CONFIG_SMP=n, building a kernel for R-Car Gen2 fails with:

Indeed, on R-Car Gen2 SoCs, secure_cntvoff_init() is not only needed for
secondary CPUs, but also for the boot CPU.  This is most visible on SoCs
with Cortex A7 cores (e.g. R-Car E2, cfr. commit 9ce3fa68 ("ARM:

When delivering a signal to a task that is using rseq, we call into
__rseq_handle_notify_resume() so that the registers pushed in the
sigframe are updated to reflect the state of the restartable sequence
(for example, ensuring that the signal returns to the abort handler if
necessary).

However, if the rseq management fails due to an unrecoverable fault when
accessing userspace or certain combinations of RSEQ_CS_* flags, then we
will attempt to deliver a SIGSEGV. This has the potential for infinite
recursion if the rseq code continuously fails on signal delivery.

Avoid this problem by using force_sigsegv() instead of force_sig(), which
is explicitly designed to reset the SEGV handler to SIG_DFL in the case
of a recursive fault. In doing so, remove rseq_signal_deliver() from the
internal rseq API and have an optional struct ksignal * parameter to
rseq_handle_notify_resume() instead.
