      Pull clock framework updates from Mike Turquette:
       "The clock framework changes contain the usual driver additions,
        enhancements and fixes mostly for ARM32, ARM64, MIPS and Power-based
        devices.
      
        Additionally the framework core underwent a bit of surgery with two
        major changes:
      
         - The boundary between the clock core and clock providers (e.g clock
           drivers) is now more well defined with dedicated provider helper
           functions.  struct clk no longer maps 1:1 with the hardware clock
           but is a true per-user cookie which helps us tracker users of
           hardware clocks and debug bad behavior.
      
         - The addition of rate constraints for clocks.  Rate ranges are now
           supported which are analogous to the voltage ranges in the
           regulator framework.
      
        Unfortunately these changes to the core created some breakeage.  We
        think we fixed it all up but for this reason there are lots of last
        minute commits trying to undo the damage"

      kernel: make READ_ONCE() valid on const arguments · dd369297
      Linus Torvalds authored
      
      
      The use of READ_ONCE() causes lots of warnings witht he pending paravirt
      spinlock fixes, because those ends up having passing a member to a
      'const' structure to READ_ONCE().
      
      There should certainly be nothing wrong with using READ_ONCE() with a
      const source, but the helper function __read_once_size() would cause
      warnings because it would drop the 'const' qualifier, but also because
      the destination would be marked 'const' too due to the use of 'typeof'.
      
      Use a union of types in READ_ONCE() to avoid this issue.
      
      Also make sure to use parenthesis around the macro arguments to avoid
      possible operator precedence issues.

      x86: pte_protnone() and pmd_protnone() must check entry is not present · e3a1f6ca
      David Vrabel authored
      Since _PAGE_PROTNONE aliases _PAGE_GLOBAL it is only valid if
      _PAGE_PRESENT is clear.  Make pte_protnone() and pmd_protnone() check
      for this.
      
      This fixes a 64-bit Xen PV guest regression introduced by 8a0516ed
      
      
      ("mm: convert p[te|md]_numa users to p[te|md]_protnone_numa").  Any
      userspace process would endlessly fault.
      
      In a 64-bit PV guest, userspace page table entries have _PAGE_GLOBAL set
      by the hypervisor.  This meant that any fault on a present userspace
      entry (e.g., a write to a read-only mapping) would be misinterpreted as
      a NUMA hinting fault and the fault would not be correctly handled,
      resulting in the access endlessly faulting.

      debug: prevent entering debug mode on panic/exception. · 5516fd7b
      Colin Cross authored
      
      
      On non-developer devices, kgdb prevents the device from rebooting
      after a panic.
      
      Incase of panics and exceptions, to allow the device to reboot, prevent
      entering debug mode to avoid getting stuck waiting for the user to
      interact with debugger.
      
      To avoid entering the debugger on panic/exception without any extra
      configuration, panic_timeout is being used which can be set via
      /proc/sys/kernel/panic at run time and CONFIG_PANIC_TIMEOUT sets the
      default value.
      
      Setting panic_timeout indicates that the user requested machine to
      perform unattended reboot after panic. We dont want to get stuck waiting
      for the user input incase of panic.

      kdb: Const qualifier for kdb_getstr's prompt argument · 32d375f6
      Daniel Thompson authored
      
      
      All current callers of kdb_getstr() can pass constant pointers via the
      prompt argument. This patch adds a const qualification to make explicit
      the fact that this is safe.
