      [PATCH] sunrpc dcache cleanup · b72d7dcb
      Andrew Morton authored
      Patch from Dipankar Sarma <dipankar@in.ibm.com>
      
      All fs should be using dcache APIs to manipulate dcache hash lists.  This is
      in line with the dcache cleanup patch (dcache_rcu-1) from Maneesh that Linus
      accepted.  This seems like a reasonable cleanup.  One change though, we don't
      need to grab dcache_lock while deleting dentries from the private list and
      __d_drop() should suffice here.

      [PATCH] disassociate_ctty SMP fix · 01ffc65c
      Andrew Morton authored
      Patch from Rik van Riel <riel@conectiva.com.br>
      
      the following patch, against today's BK tree, fixes a small
      SMP race in disassociate_ctty.  This function gets called
      from do_exit, without the BKL held.
      
      However, it sets the *tty variable before grabbing the bkl,
      then makes decisions on what the variable was set to before
      the lock was grabbed, despite the fact that another process
      could modify its ->tty pointer in this same function.

      [PATCH] provide uniproc write_trylock() · 40095952
      Andrew Morton authored
      Patch from Oleg Drokin <green@namesys.com>, Nikita Danilov <Nikita@Namesys.COM>
      
      There is no uniprocessor definition of _raw_write_trylock(), so
      write_trylock() doesn't work on UP.

      [PATCH] genhd warnings fix · d89ff79e
      Andrew Morton authored
      I have a whole bunch of silly compile warning fixes here, arising from
      building the kernel for a 64-bit target.  Some are trivial, some are genuine
      printk bugs.
      
      assuming dev_t is unsigned generates a warning on ppc64.  Cast it.

      [CPUFREQ] add support for cpufreq governors. · 2e585809
      Dave Jones authored
      More bits from Dominik.
      
      Most cpufreq drivers (in fact, all except one, longrun) or even most
      cpu frequency scaling algorithms only offer the CPU to be set to one
      frequency. In order to offer dynamic frequency scaling, the cpufreq
      core must be able to tell these drivers of a "target frequency". So
      these specific drivers will be transformed to offer a "->target"
      call instead of the existing "->setpolicy" call. For "longrun", all
      stays the same, though.
      
      How to decide what frequency within the CPUfreq policy should be used?
      That's done using "cpufreq governors". Two are already in this patch
      -- they're the already existing "powersave" and "performance" which
      set the frequency statically to the lowest or highest frequency,
      respectively. At least two more such governors will be ready for
      addition in the near future, but likely many more as there are various
      different theories and models about dynamic frequency scaling
      around. Using such a generic interface as cpufreq offers to scaling
      governors, these can be tested extensively, and the best one can be
      selected for each specific use.
      
      Basically, it's the following flow graph:
      
      CPU can be set to switch independetly    |         CPU can only be set
            within specific "limits"           |       to specific frequencies
      
                                       "CPUfreq policy"
                      consists of frequency limits (policy->{min,max})
                           and CPUfreq governor to be used
                               /                    \
                              /                      \
                             /                       the cpufreq governor decides
                            /                        (dynamically or statically)
                           /                         what target_freq to set within
                          /                          the limits of policy->{min,max}
                         /                                \
                        /                                  \
              Using the ->setpolicy call,              Using the ->target call,
                  the limits and the                    the frequency closest
                   "policy" is set.                     to target_freq is set.
                                                        It is assured that it
                                                        is within policy->{min,max}

      [PATCH] Fix stack handling in acpi_wakeup.S · 26a97bb1
      Pavel Machek authored
      This fixes stack handling in acpi_wakeup.S, and makes stack smaller so
      that wakeup code actually fits inside memory allocated for it. Plus
      someone renamed .L1432 to something meaningful.
