      x86/smpboot: Init apic mapping before usage · 1e90a13d
      Thomas Gleixner 提交于
      The recent changes, which forced the registration of the boot cpu on UP
      systems, which do not have ACPI tables, have been fixed for systems w/o
      local APIC, but left a wreckage for systems which have neither ACPI nor
      mptables, but the CPU has an APIC, e.g. virtualbox.
      
      The boot process crashes in prefill_possible_map() as it wants to register
      the boot cpu, which needs to access the local apic, but the local APIC is
      not yet mapped.
      
      There is no reason why init_apic_mapping() can't be invoked before
      prefill_possible_map(). So instead of playing another silly early mapping
      game, as the ACPI/mptables code does, we just move init_apic_mapping()
      before the call to prefill_possible_map().
      
      In hindsight, I should have noticed that combination earlier.
      
      Sorry for the churn (also in stable)!

      Lv Zheng 提交于
      The last step of the method termination should be the end of the method
      serialization. Otherwise, the steps happening after it will face the race
      issues that cannot be protected by the method serialization mechanism.
      
      This patch fixes this issue by moving the per-method-object deletion code
      prior than the end of the method serialization. Otherwise, the possible
      race issues may result in AE_ALREADY_EXISTS error in a parallel
      environment.

      ARC: boot log: refactor cpu name/release printing · d975cbc8
      Vineet Gupta 提交于
      The motivation is to identify ARC750 vs. ARC770 (we currently print
      generic "ARC700").
      
      A given ARC700 release could be 750 or 770, with same ARCNUM (or family
      identifier which is unfortunate). The existing arc_cpu_tbl[] kept a single
      concatenated string for core name and release which thus doesn't work
      for 750 vs. 770 identification.
      
      So split this into 2 tables, one with core names and other with release.
      And while we are at it, get rid of the range checking for family numbers.
      We just document the known to exist cores running Linux and ditch
      others.
      
      With this in place, we add detection of ARC750 which is
       - cores 0x33 and before
       - cores 0x34 and later with MMUv2

      ARC: boot log: refactor printing abt features not captured in BCRs · 73e284d2
      Vineet Gupta 提交于
      On older arc700 cores, some of the features configured were not present
      in Build config registers. To print about them at boot, we just use the
      Kconfig option i.e. whether linux is built to use them or not.
      So yes this seems bogus, but what else can be done. Moreover if linux is
      booting with these enabled, then the Kconfig info is a good indicator
      anyways.
      
      Over time these "hacks" accumulated in read_arc_build_cfg_regs() as well
      as arc_cpu_mumbojumbo(). so refactor and move all of those in a single
      place: read_arc_build_cfg_regs(). This causes some code redcution too:

      | arc_cpu_mumbojumbo                           752     620    -132

      ARCv2: boot log: print IOC exists as well as enabled status · 711c1f26
      Vineet Gupta 提交于
      Previously we would not print the case when IOC existed but was not
      enabled.
      
      And while at it, reduce one line off boot printing by consolidating
      the Peripheral address space and IO-Coherency which in a way
      applies to them

       "This is a standalone pull request for the fix for a regression
        introduced in -rc1 by a change to vm_insert_mixed to start using the
        PAT range tracking to validate page protections. With this fix in
        place, all the VRAM mappings for GPU drivers ended up at UC instead of
        WC.
      
        There are probably better ways to fix this long term, but nothing I'd
        considered for -fixes that wouldn't need more settling in time. So
        I've just created a new arch API that the drivers can reserve all
        their VRAM aperture ranges as WC"
