[GIT PULL] KGDB/KDB fixes for 3.19-rc4

[Jason Wessel]

Linus,

Please pull the kgdb tree bug fixes.

These have been around since 3.17 and in kgdb-next for the last 9
weeks and some will go back to -stable.

Summary of changes:

KGDB/KDB fixes and cleanups
 Cleanups
   kdb: Remove unused command flags, repeat flags and KDB_REPEAT_NONE

 Fixes
   kgdb/kdb: Allow access on a single core, if a CPU round up is deemed
      impossible, which will allow inspection of the now "trashed" kernel
   kdb: Add enable mask for the command groups
   kdb: access controls to restrict sensitive commands
