      xen: report hypervisor version · 95c7c23b
      Jeremy Fitzhardinge 提交于
      Various versions of the hypervisor have differences in what ABIs and
      features they support.  Print some details into the boot log to help
      with remote debugging.

      x86: APIC: remove apic_write_around(); use alternatives · 593f4a78
      Maciej W. Rozycki 提交于
      Use alternatives to select the workaround for the 11AP Pentium erratum
      for the affected steppings on the fly rather than build time.  Remove the
      X86_GOOD_APIC configuration option and replace all the calls to
      apic_write_around() with plain apic_write(), protecting accesses to the
      ESR as appropriate due to the 3AP Pentium erratum.  Remove
      apic_read_around() and all its invocations altogether as not needed.
      Remove apic_write_atomic() and all its implementing backends.  The use of
      ASM_OUTPUT2() is not strictly needed for input constraints, but I have
      used it for readability's sake.
      
      I had the feeling no one else was brave enough to do it, so I went ahead
      and here it is.  Verified by checking the generated assembly and tested
      with both a 32-bit and a 64-bit configuration, also with the 11AP
      "feature" forced on and verified with gdb on /proc/kcore to work as
      expected (as an 11AP machines are quite hard to get hands on these days).
      Some script complained about the use of "volatile", but apic_write() needs
      it for the same reason and is effectively a replacement for writel(), so I
      have disregarded it.
      
      I am not sure what the policy wrt defconfig files is, they are generated
      and there is risk of a conflict resulting from an unrelated change, so I
      have left changes to them out.  The option will get removed from them at
      the next run.
      
      Some testing with machines other than mine will be needed to avoid some
      stupid mistake, but despite its volume, the change is not really that
      intrusive, so I am fairly confident that because it works for me, it will
      everywhere.

      x86, xen, power: fix up config dependencies on PM · 93a0886e
      Jeremy Fitzhardinge 提交于
      Xen save/restore needs bits of code enabled by PM_SLEEP, and PM_SLEEP
      depends on PM.  So make XEN_SAVE_RESTORE depend on PM and PM_SLEEP
      depend on XEN_SAVE_RESTORE.
