      x86/umwait: Fix error handling in umwait_init() · e7409258
      Fenghua Yu authored
      Currently, failure of cpuhp_setup_state() is ignored and the syscore ops
      and the control interfaces can still be added even after the failure. But,
      this error handling will cause a few issues:
      
      1. The CPUs may have different values in the IA32_UMWAIT_CONTROL
         MSR because there is no way to roll back the control MSR on
         the CPUs which already set the MSR before the failure.
      
      2. If the sysfs interface is added successfully, there will be a mismatch
         between the global control value and the control MSR:
         - The interface shows the default global control value. But,
           the control MSR is not set to the value because the CPU online
           function, which is supposed to set the MSR to the value,
           is not installed.
         - If the sysadmin changes the global control value through
           the interface, the control MSR on all current online CPUs is
           set to the new value. But, the control MSR on newly onlined CPUs
           after the value change will not be set to the new value due to
           lack of the CPU online function.
      
      3. On resume from suspend/hibernation, the boot CPU restores the control
         MSR to the global control value through the syscore ops. But, the
         control MSR on all APs is not set due to lake of the CPU online
         function.
      
      To solve the issues and enforce consistent behavior on the failure
      of the CPU hotplug setup, make the following changes:
      
      1. Cache the original control MSR value which is configured by
         hardware or BIOS before kernel boot. This value is likely to
         be 0. But it could be a different number as well. Cache the
         control MSR only once before the MSR is changed.
      2. Add the CPU offline function so that the MSR is restored to the
         original control value on all CPUs on the failure.
      3. On the failure, exit from cpumait_init() so that the syscore ops
         and the control interfaces are not added.

      Makefile: Convert -Wimplicit-fallthrough=3 to just -Wimplicit-fallthrough for clang · bfd77145
      Joe Perches authored
      A compilation -Wimplicit-fallthrough warning was enabled by commit
      a035d552 ("Makefile: Globally enable fall-through warning")
      
      Even though clang 10.0.0 does not currently support this warning without
      a patch, clang currently does not support a value for this option.
      
        Link: https://bugs.llvm.org/show_bug.cgi?id=39382
      
      The gcc default for this warning is 3 so removing the =3 has no effect
      for gcc and enables the warning for patched versions of clang.
      
      Also remove the =3 from an existing use in a parisc Makefile:
