      perf/x86/intel: Fix INTEL_FLAGS_EVENT_CONSTRAINT* masking · 6b89d4c1
      Stephane Eranian authored
      On Intel Westmere, a cmdline as follows:
      
        $ perf record -e cpu/event=0xc4,umask=0x2,name=br_inst_retired.near_call/p ....
      
      was failing. Yet the event+ umask support PEBS.
      
      It turns out this is due to a bug in the the PEBS event constraint table for
      westmere. All forms of BR_INST_RETIRED.* support PEBS. Therefore the constraint
      mask should ignore the umask. The name of the macro INTEL_FLAGS_EVENT_CONSTRAINT()
      hint that this is the case but it was not. That macros was checking both the
      event code and event umask. Therefore, it was only matching on 0x00c4.
      There are code+umask macros, they all have *UEVENT*.
      
      This bug fixes the issue by checking only the event code in the mask.
      Both single and range version are modified.

        Remove mmiowb() from the kernel memory barrier API and instead, for

        MMIO has been performed inside the critical section.

        comments on the documentation, which is in a much better shape thanks
        to the efforts of Ben and Ingo.

           This required a broad range of surgery in text patching facilities,
           module loading, trampoline handling and other bits.
      
         - tweak page fault messages to be more informative and more
           structured.
      
         - remove DISCONTIGMEM support on x86-32 and make SPARSEMEM the
