      kbuild: Separate output directory · 5a808876
      Sam Ravnborg authored
      Separate output directory support enables the following (at least):
      o Building several configurations from the same SRC base, and in parrallel
      o Building from a RO media
      o More efficient build if files are retreived via NFS (files stored locally)
      
      Usage is simple:
      cd /path/to/kernel/src
      mkdir ~/build/kernel
      make O=~/build/kernel [Make options]
      Please note: The O= syntax must be used for ALL invocations of make.
      
      As an alternative you may set KBUILD_OUTPUT to the directory where
      to put the output files.
      
      The patch works for me, and I have tried with various configurations,
      including allnoconfig and defconfig.
      
      How it works:
      If the O= option is used, or KBUILD_OUTPUT is set then a second invocation
      of make happens in the output directory.
      The second invocation of make uses VPATH to tell make where to locate
      the files. Furthermore include options for gcc is modifyied to point
      both in the directory where the kernel src is located, and in the
      directory where the output files are located. The latter is used for
      generated .h files.
      
      When building the kernel the asm symlink is created. To support this
      a new 'include2' directory is created. Within include2/ asm is a symlink to
      the asm-$(ARCH) directory in the kernel src.
      Also when building the kernel the asm-offset.h file is created, and
      located in the include/asm-$(ARCH) directory, but included via
      <asm/asm-offset.h>.
      Therefore within include/ another asm symlink is created pointing to
      the asm-$(ARCH) directory located in the output directory.
      
      In Makefile.build the output directory is created if not already present.
      This was needed to support xfs, and oprofile.
      
      The patch is loosly based on ideas from Kai G. Roman Zippel
      introduced support for this in kconfig long time ago

      [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] d_delete-d_lookup race fix · ee9966a5
      Andrew Morton authored

      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",

      #ifdef CONFIG_SCSI_IZIP_EPP16
              [IMM_EPP_32]     = "EPP 16 bit",
      #else
              [IMM_EPP_32]     = "EPP 32 bit",

      [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;

      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.

      [PATCH] compiler warning fixes for DAC960 on alpha · f5347e30
      Andrew Morton authored
      From: Dave Olien <dmo@osdl.org>
      
      This patch is forwarded from Jay Estabrook at HP.  I've compiled the
      patch on ia32 and ia64 machines and it's good.  I also recreated
      the patch so it would apply to mm5 without fuzzy offsets.
      Here's Jay's summary of the patch:
      
      Here's a very small set of patches against 2.6.0-test4 that help the
      DAC960 driver compile cleaner (gets rid of warnings on Alpha) and help
      it to work on some old OEM'ed DAC960 cards that were sold in our older
      Alphas.
      
      The warnings are all concerned with "conversions to different size
      without cast", as pointers and longs are same size (8-bytes) but ints
      are 4-bytes, on Alpha. I don't believe the change to (long) from (int)
      will affect any 32-bit architectures, but those using LP64 like Alpha,
      ie SPARC64 and prolly IA64, will have the warnings go away.
      
      The change to make the oldest acceptable firmware version 2.70 instead
      of 2.73 is made spcific to Alpha, since it is only those cards that
      DEC OEM'ed from Mylex that would have such (as explained a bit better
      in the patch itself).

      [PATCH] dac960 devfs_name initialisation fix · c6a4440f
      Andrew Morton authored
      From: Andrey Borzenkov <arvidjaar@mail.ru>
      
      DAC960.c does it incorrectly (at least in 2.6.0-test4). It will create
      _directory_ /dev/rd/cNdM making it impossible to create compat block device
      entry with the same name.
      
      The right thing it to create separate directory for each controller/target as 
      in attached trivial patch (untested due to lack of hardware). You will need
      devfsd support for this but then you will need it for cciss or cpqarray as 
      well and possibly for others. Which returns us to the problem of devfsd 
      maintenance ...
