Scalable MCA (SMCA) is a new feature in AMD Fam17h processors
which indicates presence of MCA extensions.

MCA extensions expands existing register space for the MCE banks
and also introduces a new MSR range to accommodate new banks.

Add the detection bit.

Make CONFIG_MICROCODE a bool. It was practically a bool already anyway,
since early loader was forcing it to =y.

Regardless, there's no real reason to have something be a module which
gets built-in on the majority of installations out there. And its not
like there's noticeable change in functionality - we still can load late
microcode - just the module glue disappears.

The per CPU thermal vector init code checks if the thermal
vector is already installed and complains and bails out if it
is.

This happens after kexec, as kernel shut down does not clear the
thermal vector APIC register.

This causes two problems:

1. So we always do not fully initialize thermal reports after
   kexec. The CPU is still likely initialized, as the previous
   kernel should have done it. But we don't set up the software
   pointer to the thermal vector, so reporting may end up with a
   unknown thermal interrupt message.

2. Also it complains for every logical CPU, even though the
   value is actually derived from BP only.

The problem is that we end up with one message per CPU, so on
larger systems it becomes very noisy and messes up the otherwise
nicely formatted CPU bootup numbers in the kernel log.

Just remove the check. I checked the code and there's no valid
code paths where the thermal init code for a CPU could be called
multiple times.

Why the kernel does not clean up this value on shutdown:

The thermal monitoring is controlled per logical CPU thread.
Normal shutdown code is just running on one CPU. To disable it
we would need a broadcast NMI to all CPUs on shut down. That's
overkill for this. So we just ignore it after kexec.

People reported that when allocating crashkernel memory using
the ",high" and ",low" syntax, there were cases where the
reservation of the high portion succeeds but the reservation of
the low portion fails.

Then kexec can load the kdump kernel successfully, but booting
the kdump kernel fails as there's no low memory.

The low memory allocation for the kdump kernel can fail on large
systems for a couple of reasons. For example, the manually
specified crashkernel low memory can be too large and thus no
adequate memblock region would be found.

Therefore, we try to reserve low memory for the crash kernel
*after* the high memory portion has been allocated. If that
fails, we free crashkernel high memory too and return. The user
can then take measures accordingly.

Pave the way for checking the current patch level of the
microcode in a core. We want to be able to do stuff depending on
the patch level - in this case decide whether to update or not.
But that will be added in a later patch.

Drop unused local var uci assignment, while at it.

Integrate a fix for 32-bit and CONFIG_PARAVIRT from Takashi Iwai:

 Use native_rdmsr() in check_current_patch_level() because with
 CONFIG_PARAVIRT enabled and on 32-bit, where we run before
 paging has been enabled, we cannot deref pv_info yet. Or we
 could, but we'd need to access its physical address. This way of
 fixing it is simpler. See:

Bank 4 MCEs are logged and reported only on the node base core
(NBC) in a socket. Refer to the D18F3x44[NbMcaToMstCpuEn] field
in Fam10h and later BKDGs. The node base core (NBC) is the
lowest numbered core in the node.

This patch ensures that we inject the error on the NBC for bank
4 errors. Otherwise, triggering #MC or APIC interrupts on a core
which is not the NBC would not have any effect on the system,
i.e. we would not see any relevant output on kernel logs for the
error we just injected.

  virtualization and wanting to use 32-bit PAE kernels and wanting to
  have working DMA operations - this configures it for them"

Leandro Awa writes:
 "After switching to version 4.1.6, our parallelized and distributed
  workflows now fail consistently with errors of the form:

  T34: ./regex.c:39:22: error: config.h: No such file or directory

  From our 'git bisect' testing, the following commit appears to be the
  possible cause of the behavior we've been seeing: commit 766c4cbf"

Al Viro says:
 "What happens is that 766c4cbf got the things subtly wrong.

  We used to treat d_is_negative() after lookup_fast() as "fall with
  ENOENT".  That was wrong - checking ->d_flags outside of ->d_seq
  protection is unreliable and failing with hard error on what should've
  fallen back to non-RCU pathname resolution is a bug.

  Unfortunately, we'd pulled the test too far up and ran afoul of
  another kind of staleness.  The dentry might have been absolutely
  stable from the RCU point of view (and we might be on UP, etc), but
  stale from the remote fs point of view.  If ->d_revalidate() returns
  "it's actually stale", dentry gets thrown away and the original code
  wouldn't even have looked at its ->d_flags.

  What we need is to check ->d_flags where 766c4cbf

 does (prior to
  ->d_seq validation) but only use the result in cases where we do not
  discard this dentry outright"

Pull power management and ACPI fixes from Rafael Wysocki:
 "These are four fixes for bugs in the devfreq and cpufreq subsystems,
  including two regression fixes (one for a recent regression and one
  for a problem introduced in 4.2).

  Specifics:

   - Two fixes for cpufreq regressions, an acpi-cpufreq driver one
     introduced during the 4.2 cycle when we started to preserve cpufreq
     directories for offline CPUs and a general one introduced recently
     (Srinivas Pandruvada).

   - Two devfreq fixes, one for a double kfree() in an error code path
     and one for a confusing sysfs-related failure (Geliang Tang, Tobias
     Jakobi)"
