The bindings required interrupts for all SoCs but actually only the PWM
timer clocksource (for S3C/S5P SoCs) was using them. This PWM timer
clocksource driver is not used on Exynos SoCs thus the interrupts can be
marked as optional.

First patch is about returning failure (rather than success) when
max_append_sectors is 0. This prevents bio_iov_iter_get_pages() from
getting into an endless loop.
Second patch enables issuing zone-append with iov_iter of bvec type.
It adds a helper which is similar to __bio_iov_bvec_add_pages()

Add CONFIG_CLK_xxx for i.MX ARMv7 platforms, and use it as build option
instead of CONFIG_SOC_xxx, the CONFIG_CLK_xxx will be selected by default
according to CONFIG_SOC_xxx, COMPILE_TEST will be also supported.

This is needed to be able to manage enclave resources state, enclave
notifications and have a reference of the PCI device that handles
command requests for enclave lifetime
in order to be able to call them after the system has booted.

If the microcode late loading and bug mitigation logic needs to turn
off SMT, it must use the hot plug infrastructure, not the boot time call
"cpu_smt_disable".
Update "cpu_smt_disable" to use the hot plug infrastructure to turn off
SMT when the system is in state running.

The usage of static_cpu_has in bugs.c file is counter-productive
since the code is executed once but there is extra effort to patch
it and keep alternatives in a special section --- so there is both
space and time cost.
Quote from _static_cpu_has definition:

* Static testing of CPU features.
While doing microcode late loading, need to probe again all the
CPU features after the microcode has been loaded. Before probing
the CPU features and bug, need to clear the current bug bits. The
new function, cpu_clear_bug_bits, will clear all the bug bits and
then set them.

This RFC patch set aims to provide the ability to re-evaluate all CPU
features and take proper bug mitigation in place after a microcode
late loading.
This was debated last year and this patch set implements a subset of
point #2 from Thomas Gleixner's idea:
If we have loaded a broken microcode at boot time, all the
speculation features will be blacklisted. Created a new
function for Intel CPUs to verify if we have a broken microcode
loaded or not and whitelist/blacklist features as needed.
This has to be done before get_cpu_cap because it uses these
Adapt check_bugs to be callable at runtime after the
microcode late loading has been done.
Also update SRBDS to reset the default value for srbds_mitigation and call
update_srbds_msr on all CPUs.
