      [PATCH] CPU scheduler CAN_MIGRATE fix · 9e3a8956
      Andrew Morton authored
      From: Andrew Theurer <habanero@us.ibm.com>
      
      This change:
      http://linux.bkbits.net:8080/linux-2.5/diffs/kernel/sched.c@1.202
      
      does not seem to make sense:
      
      #define CAN_MIGRATE_TASK(p,rq,this_cpu)					\
      	((!idle || (jiffies - (p)->last_run > cache_decay_ticks)) &&    \
      		!task_running(rq, p) &&					\
      			cpu_isset(this_cpu, (p)->cpus_allowed))
      
      It should be just the opposite; an idle cpu should be able to have a more
      aggressive steal, and a busy cpu should not.

      [PATCH] Reduce random driver lock contention · c3ee1c75
      Andrew Morton authored
      From: Matt Mackall <mpm@selenic.com>
      
      The new locking in the random driver is consuming 60% of CPU resources in
      Anton's monster power5 boxes.
      
      
      Basically, when the primary pool is 7/8th full, we shut off the firehose
      and go into a trickle mode to keep the pool fresh.  Saves CPU for everyone
      and should make the contention drop off the charts too (though the trickle
      factor might need adjusting again for Origin-class machines).

      [PATCH] fix Summit srat.h includes · e623ce48
      Andrew Morton authored
      From: Dave Hansen <haveblue@us.ibm.com>
      
      I was compiling for my plain 'ol PC, and was getting unresolved symbols
      for get_memcfg_from_srat() and get_zholes_size().  The CONFIG_NUMA
      definition right now allows it to be turned on for plain old X86_PC. 
      Does anyone know why this is? 
      
      depends on SMP && HIGHMEM64G &&
                (X86_PC || X86_NUMAQ || X86_GENERICARCH ||
                        (X86_SUMMIT && ACPI && !ACPI_HT_ONLY))
      
      In any case, the summit code incorrectly assumes in at least 2 places
      that NUMA && !NUMAQ means summit.  Someone was evidently trying to cover
      the generic subarch case, but that's already taken care of by the lovely
      config system and CONFIG_ACPI_SRAT.  This patch fixes those assumptions
      and adds a nice little warning for people that try to #include srat.h
      without having srat support turned on.

      [PATCH] mwave locking fixes · 5ee6ddc2
      Andrew Morton authored
      From: Manfred Spraul <manfred@colorfullife.com>
      
      The mwave driver uses a user space daemon for some modem operations. The
      user space daemon calls ioctl(,IOCTL_MW_GET_IPC), and the driver returns
      after an interrupt arrived. The actual wait used
      interruptible_sleep_on(), which can lead to lost wakeups. A local 
      spinlock on the stack is used to close that race, but this is broken on 
      SMP, perhaps even with preempt.
      
      The attached patch fixes that by switching to the normal 
      add_wait_queue/test_if_race_occured/schedule/remove_wait_queue sequence.

      [PATCH] ext3: remove debug code · 712c0c6f
      Andrew Morton authored
      ext3 has fancy test harness code which allows you to simulate crashes (for
      testing recovery).  It will make the underlying disk start ignoring writes a
      specified number of seconds after the mount.
      
      It's inoperative without an additional offline patch anyway, and it's doing
      hacky things which scared Al.  So kill it; I'll maintain it in the separate
      ext3 debug patch.

      [PATCH] tidy up lib/inflate.c error messages · 28160177
      Andrew Morton authored
      From: Andre McCurdy <armcc2000@yahoo.com>
      
      There is some inconsistency within lib/inflate.c and its users about
      whether the error message text or the error() function should provide
      the '\n'.
      
      This patch tries to make everyone consistent - by removing the
      newline from all message texts, and adding one to the only error()
      function which did not provide it (in init/do_mounts_rd.c).

      [PATCH] remap file pages MAP_NONBLOCK fix · be98a9cd
      Andrew Morton authored
      From: Rajesh Venkatasubramanian <vrajesh@eecs.umich.edu>
      
      The remap_file_pages system call with MAP_NONBLOCK flag does not
      install file-ptes when the required pages are not found in the
      page cache. Modify the populate functions to install file-ptes
      if the mapping is non-linear and the required pages are not found
      in the page cache.
      
      Patch is for test4-mm6. Compiles and boots. Patch tested using the
      programs at:

      [PATCH] d_delete-d_lookup race fix · ee9966a5
      Andrew Morton authored
      From: Maneesh Soni <maneesh@in.ibm.com>
      
      d_delete() calls dentry_iput() after releasing the per dentry lock.  This
      can race with __d_lookup and lead to situation where we can make dentry
      negative with ref count > 1.  The following patch makes dentry_iput() to
      hold per dentry lock till d_inode is NULL and dentry has been removed from
      d_alias list.

      [PATCH] make selinux enable param config option, enabled by · beb12afa
      Andrew Morton authored
      From: James Morris <jmorris@redhat.com>
      
      This patch against current bk makes the recently added SELinux boot
      parameter feature a configurable option, and enables SELinux by default
      when selected.  These changes were made following feedback including 
      discussion on the SELinux list.
      
      The rationale for the changes is to allow SELinux to be be configured and
      enabled unconditionally.  If the boot parameter option is selected, then
      SELinux is now enabled unless selinux=0 is specified at the kernel command
      line.

      [PATCH] Fix imm.c again · 94c5d6eb
      Andrew Morton authored
      From: Adrian Bunk <bunk@fs.tum.de>
      
      Earlier patch wasn't correct especially in the !CONFIG_SCSI_IZIP_EPP16
      case, reading all uses of this array (IMM_MODE_STRING is used to print the
      corresponding string in printks).
      
      If I'm not misunderstanding it, CONFIG_SCSI_IZIP_EPP16 means "use 16bit 
      even when 32bit is requested".
      
      It seems the right solution is
      
      static char *IMM_MODE_STRING[] =
      {
              [IMM_AUTODETECT] = "Autodetect",
              [IMM_NIBBLE]     = "SPP",
              [IMM_PS2]        = "PS/2",
              [IMM_EPP_8]      = "EPP 8 bit",
              [IMM_EPP_16]     = "EPP 16 bit",
      #ifdef CONFIG_SCSI_IZIP_EPP16
              [IMM_EPP_32]     = "EPP 16 bit",
      #else
              [IMM_EPP_32]     = "EPP 32 bit",
      #endif
              [IMM_UNKNOWN]    = "Unknown",

      [PATCH] Move ikconfig to /proc/config.gz · f261ecb2
      Andrew Morton authored
      From: "Randy.Dunlap" <randy.dunlap@verizon.net>
      
      
      The SuSE kernels place their ikconfig info at /proc/config.gz: in a
      different place, and compressed.  We thought it was a good idea to do it
      that way in 2.6 as well.
      
      - gzip the /proc config file, put it in /proc/config.gz;
      
      - Based on a SuSE patch by Oliver Xymoron <oxymoron@waste.org>, which was
        derived from a patch by Nicholas Leon <nicholas@binary9.net>
      
      - change /proc/ikconfig/built_with to /proc/config_build_info;
      
      - cleanup ikconfig init/exit entry points (static, __init, __exit);
      
      - Makefile help from Sam Ravnborg;

      ikconfig cleanup
      EDESC
      From: Stephen Hemminger <shemminger@osdl.org>
      
      Simplify and cleanup the code:
      	- use single interface to seq_file where possible
      	- don't need to do as much of the /proc interface, only read
      	- use copy_to_user to avoid char at a time copy
      	- remove unneccesary globals
      	- use const char[] rather than const char * where possible.
      
      Didn't change the version since interface doesn't change.
