      x86, UV: Fix and clean up bau code to use uv_gpa_to_pnode() · 1d21e6e3
      Robin Holt authored 
      Create an inline function to extract the pnode from a global
physical address and then convert the broadcast assist unit to
use the newly created uv_gpa_to_pnode function.

The open-coded code was wrong as well - it might explain a
few of our unexplained bau hangs.

      x86: Don't print number of MCE banks for every CPU · 93ae5012
      Roland Dreier authored 
      The MCE initialization code explicitly says it doesn't handle
asymmetric configurations where different CPUs support different
numbers of MCE banks, and it prints a big warning in that case.

Therefore, printing the "mce: CPU supports <x> MCE banks"
message into the kernel log for every CPU is pure redundancy
that clutters the log significantly for systems with lots of
CPUs.

      x86, UV: Fix information in __uv_hub_info structure · 036ed8ba
      Robin Holt authored 
      A few parts of the uv_hub_info structure are initialized
incorrectly.

 - n_val is being loaded with m_val.
 - gpa_mask is initialized with a bytes instead of an unsigned long.
 - Handle the case where none of the alias registers are used.

Lastly I converted the bau over to using the uv_hub_info->m_val
which is the correct value.

Without this patch, booting a large configuration hits a
problem where the upper bits of the gnode affect the pnode
and the bau will not operate.

      x86: Document linker script ASSERT() quirk · a5912f6b
      Ingo Molnar authored 
      Older binutils breaks if ASSERT() is used without a sink
for the output.

For example 2.14.90.0.6 is known to be broken, the link
fails with:

  LD      .tmp_vmlinux1
  ld:arch/x86/kernel/vmlinux.lds:678: parse error

Document this quirk in all three files that use it.

  See:    http://marc.info/?l=linux-kbuild&m=124930110427870&w=2
  See[2]: d2ba8b21 ("x86: Fix assert syntax in vmlinux.lds.S")
