      Martin Schwidefsky authored
      From: Utz Bacher <utz.bacher@de.ibm.com>
      From: Cornelia Huck <cohuck@de.ibm.com>
      
      Common i/o layer changes:
       - Consolidate store channel subsystem characteristics from its three
         users (css, cmf and qdio) to a single location.
       - Always use new stipd format and move creation of global path group
         to channel subsystem init function. Add dummy init_IRQ to setup.c
         and remove requestirq.c.
       - Remove bogus CHPID_LONGS define.
       - Add more magic to catch chpids coming online again without generating
         machine checks.
       - Fix check for unsolicited interrupts. Deferred cc=1 indicates a
         solicited interrupt.
       - Fix progress indication in qdio summary bytes to avoid loosing interrupts.
       - Rename console_device to console_devno to avoid naming conflict.

      [PATCH] 64 bit bug in radix-tree lookup. · 48a3a8cd
      Martin Schwidefsky authored
      The radix tree functions __lookup and __lookup_tag uses (1 << shift) in
      their index calculations.  On 64 bit systems the shift can be bigger than
      32.  The shift of an integer by more than 32 bits evaluates to zero which
      causes the lookup to fail.

      [PATCH] es7000 subarch update for target_cpus() · 6b9956c0
      Natalie Protasevich authored
      This is ES7000 sub arch update.  The tiny patch below fixes a bug that
      results in boot problem on all ES7000 partitions with numbers higher than
      0.  Currently, target_cpus() returns incorrect cpumask value since it
      indexes bits by the logical APIC ID, not by CPU number.  The patch affects
      only ES7000 sub arch.  It was tested extensively on the system with
      multiple partitions.

      [PATCH] Another batch of fbcon fixes · 21aff035
      Antonino Daplas authored
      - Update display->vrows when fbset changes certain fields in var (such as
        color depth) but without changing the display resolution.  This might
        produce concommitant changes in other fields such as and especially
        var->yres_virtual.
      
      - Clear the FBINFO_MISC_MODECHANGEUSER flag _before_ issuing a
        notifier_call_chain().  Clearing it after the notifier_call_chain() will
        cause fbcon to go into an infinite loop.

      [PATCH] Mode Switch in fbcon_blank() · bd8450b9
      Antonino Daplas authored
      As we've discussed in another thread, below is a diff that will do a set_par()
      as late as possible when there is KD_TEXT<->KD_GRAPHICS switch.  The set_par()
      will be forced in fbcon_resize() instead.
      
      Not sure if this has repercussions with the other drivers, but this patch
      fixed the X nv driver hanging when switching to the console.  (I believe the
      crash is actually caused by an early set_par() -- while in fbcon_blank. 
      Removing the set_par in fbcon_blank fixed the hang but caused cursor sprite
      and display corruption).

      1 Seems that nVidia hardware has a limit on clipping coordinates that is
        also dependent on the color depth of the framebuffer.

        (RGB565).  The fix has been submitted several times in lkml and this list
        but was never applied.
      
      3 Search all I2C/DDC busses for the EDID block instead of just the first
        bus.

      [PATCH] sparse: define max kernel symbol length and clean up errors in kernel/kallsyms.c · 77e5ab66

      kernel/kallsyms.c:143:22: warning: bad constant expression
      
      Now the cause of sparse warnings is that it does not handle runtime array
      dimensioning (which I take it is a sparse problem), but in this particular
      case it _might_ make sense to change the runtime allocation to compile
      time, as the upper size of the array is known, because the code in
      kernel/kallsyms.c clearly uses 127 (or 128) as "magic constant" for kernel
      symbol (array) length, and in the other hand in include/linux/module.h
      there is: #define MODULE_NAME_LEN (64 - sizeof(unsigned long))
      
      The only concern is that the array become quite big (the original comment
      of it being "pretty small" no longer applies ...).  One way to help that
      would be to use buffer[] also in place of namebuf[], but that would be
      little tricky as the format string should be before the symbol name ...

      [PATCH] Bugfix for CLOCK_REALTIME absolute timer · 7fe672b1
      George Anzinger authored
      As required by the standard, this patch adds to POSIX ABSOLUTE timers the
      functionality of adjusting the timer when the clock is set so that it still
      expires at the specified time (provided that time has not passed, in which
      case the timer expires immeadiatly).
      
      The standard is, IMNSOHO, a bit vague on just how repeating timers are to
      be handled so I made some choices:
      
      1) If an absolute timer is to expire every N intervals, we assume that
         the expiries should happen at those specified times after clock setting.
          I.e.  we adjust the repeat timer as well as the initial timer.  (The
         other option would be to treat the repeating timers as relative and not
         to adjust them.)
      
      2) If a clock set moves the the clock prior to the initial expiry time
         AND that time has already passed and been signaled, the current repeat
         timer is adjusted, i.e.  we DO NOT go back to the initial time and
         repeat that.  (The other option is to treat this case as a new request
         with the initial timer parameters (which by this time we have lost).)
      
      3) If time is advanced such that it appears that several expiries have
         been missed, the overrun count will reflect the misses.  (The other
         option is to not reflect this in the overrun.) At the same time, nothing
         is done to acknowledge, to the user, that we are repeating expiries when
         the clock is retarded.

      [PATCH] ppc64: janitor log_rtas_error() call arguments · e1148e37
      Paul Mackerras authored
      This patch from Linas Vepstas (rediffed by me) fixes the confusing argument
      aliasing of the log_rtas_error() subroutine.
      
      This patch makes no functional changes, it just cleans up some strange
      usage.
      
      The rtas_args used to communicate with firmware are always taken from the
      paca struct, so as to keep the args at a fixed, low-memory location.  But
      the log_rtas_error() routine also took an rtas_args pointer, which it
      assumed was aliased to the paca struct.  This aliasing is both
      un-neccessary, and confusing; this patch eliminates this confusion.

      [PATCH] ppc64: PACA cleanup · 16b004a7
      David Gibson authored
      Cleanup the PPC64 PACA structure.  It was previously a big mess of
      unecessary fields, overengineered cache layout and uninformative comments. 
      This is essentially a rewrite of include/asm-pp64/paca.h with associated
      changes elsewhere.  The patch:
      
      - Removes unused PACA fields
      
      - Removes uneeded #includes
      
      - Uses gcc attributes instead of explicit padding to get the desired
        cacheline layout, also rethinks the layout and comments accordingly.
      
      - Better comments where asm or firmware dependencies apply non-obvious
        layout constraints.
      
      - Splits up the pointless STAB structure, letting us move its elements
        independently.
      
      - Uses offsetof instead of hardcoded offset in spinlocks.
      
      - Eradicates xStudlyCaps identifiers
      
      - Replaces PACA guard page with an explicitly defined emergency stack

      [PATCH] ppc64: remove RTAS arguments from PACA · 78c39c9f
      David Gibson authored
      This patch removes the RTAS arguments structure on ppc64 from the PACA. 
      The args have to be in the RMO, but since we have a global spinlock for
      RTAS anyway, there's no reason to have a separate copy of the args per-CPU.
       This patch replaces the PACA field with a single instance in the global
      rtas structure.
      
      The one exception is for the rtas_stop_self() call, which can't take the
      lock, because it never returns.  But it has a fixed set of arguments, so we
      can use another global instance which is initialized at boot.
      
      This lets us remove rtas.h from paca.h, which substantially reduces overall
      #include hairiness (because paca.h is now, as it wants to be, a nice
      low-level structure-defining header which relies on very little and can
      safely be included almost anywhere).  Although it does add some noise to
      the patch, because a bunch of places relied on the indirect inclusion of
      rtas.h, or even more indirect inclusions (see the hunks applying to eeh.h
      and current.h!).
