JFYI, when comparing v4.1[1] to v4.1-rc8[3], the summaries are:
  - build errors: +44/-7

  + /home/kisskb/slave/src/arch/arm/mm/dump.c: error:
'L_PTE_MT_BUFFERABLE' undeclared here (not in a function):  => 81:10
  + /home/kisskb/slave/src/arch/arm/mm/dump.c: error:
'L_PTE_MT_DEV_CACHED' undeclared here (not in a function):  => 117:10
  + /home/kisskb/slave/src/arch/arm/mm/dump.c: error:
'L_PTE_MT_DEV_NONSHARED' undeclared here (not in a function):  =>
108:10

I'm rather ignoring this because I don't see these errors here.  This
is one of the problems of just throwing out build reports.  With zero
information such as a configuration or a method on how to cause the
errors, it's pretty much worthless to post errors.

Folk who do build testing need to be smarter, and consider what it's
like to be on the receiving end of their report emails...

Fortunately the kisskb service has good bookkeeping of build logs and configs.

Re-adding the lost URL:

  1. Open URL in web browser,
  2. Click on "Failed", next to "arm-randconfig",
  3. Click on "Download", next to "arm-randconfig",
  4. Reproduce,
  5. Fix,
  6. Profit! ;-)

Thanks!

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
