      [NWFPE] performance improvements [Part 2] · 5f7d2c16
      Ralph Siemsen authored
      Second part of NWFPE improvements.  Builds on top of patch 1464/1.
      
      Remove unused code.  And fix a function prototype to match function.
      No impact on generated code or NWFPE performance.

      [NWFPE] Performance improvements [Part 1] · 95a3352a
      Ralph Siemsen authored
      This is the first of a series of patches to NWFPE, which aim to bring
      the performance improvements from the netwinder.org CVS tree into the
      mainline ARM kernel.
      
      This patch is merely a reformatting of the NWFPE sources.  All files
      were processed with "indent -kr -i8 -ts8 -sob -l132 -ss" and a few
      manual fixups. Exception: the softfloat files have not been touched.
      
      This patch should be applied after the 5 patches previously published
      by RMK on linux-arm-kernel have been applied.

      kbuild: remove dependency on compile.h · db0d6263
      Kai Germaschewski authored
      We had a dummy dependency on include/linux/compile.h, but it really caused
      more trouble than benefits. It's not actually needed for the module
      postprocessing, it was only put there to make sure we recognize when
      gcc changed under us. However, we really can only do so much, and
      the rest of kbuild won't notice a changed gcc either, so if the user replaces
      gcc during a build, he just can't rely on the build doing the right thing.
      
      The common cases are still covered, anyway. When the command to invoke
      gcc changes ("CC=gcc32") we notice, and when the path to
      
      	/usr/lib/gcc-lib/i386-redhat-linux/2.96/include/stdarg.h
      
      changes (which luckily contains the "2.96", we'll notice and handle that,
      too.

      [PATCH] kbuild: do not run split-include for all compilations · 1ef75673
      Sam Ravnborg authored
      When a rule in the top-level Makefile includes scripts as one
      of the prerequisites it inherits FORCE, and thus is always build.
      include/linux/autoconf.h recently included scripts hereby forcing
      split-include to be run for each compilation.
      
      Fix all rules that lists scripts as a prerequisite but did not list FORCE.
      Fixed by listing the executable needed direct.

      do_mounts: Fix CONFIG_BLK_DEV_MD=m case · eae6fb05
      Kai Germaschewski authored
      We don't really have a nice way to say "compile this when CONFIG_FOO
      is y, don't otherwise".
      
      Alternatives are:
      
      obj-$(subst m,,$(CONFIG_FOO)) := foo.o
      
      or
      
      obj-$(CONFIG_FOO)	:= foo.o
      obj-m :=
      
      or
      
      obj-y			:= do_foo.o
      do_foo-$(CONFIG_FOO)	:= foo.o
      
      I chose the last one, though I'm not particularly happy with either.

      Patch from Stephen Cameron <steve.cameron@hp.com>
      
      Add CCISS_GETLUNINFO ioctl.
      
      This ioctl returns the LUNID, number of partitions, and current number of
      opens on a logical volume.  Used by the array config utility or any app that
      needs to send passthrough commands to a particular logical disk.

      [PATCH] cciss: retry bus resets · f51e4f73
      Andrew Morton authored
      Patch from Stephen Cameron <steve.cameron@hp.com>
      
      Make cciss driver retry 3rd party bus reset aborted commands up to 3 times.
      (ported to 2.5 by me, original patch by Charles White)
      
      This is needed for a multi port storage box that can have multiple hosts
      connected to it, or be used in a multipath configuration.  In certain
      configurations SCSI bus resets initiated by one host may affect another host.

      [PATCH] cciss: fix unlikely startup problem · db54a480
      Andrew Morton authored
      Patch from Stephen Cameron <steve.cameron@hp.com>
      
      
      * Make cciss driver wait longer for board to enter simple mode to
        handle an unlikely corner case.  (Hot replace of failed 144GB
        drive in RAID 5 set at just the wrong time prior to driver loading
        can make the board take a longer than usual time to go into "simple
        mode".  Without the patch, the driver gives up too early, and consequently
        doesn't work.  (A reboot will generally "fix" it.)  This patch avoids
        the problem.
      * Fix a couple ioctls to return EAGAIN instead of inappropriate EFAULT.

      [PATCH] hugetlb: fix MAP_FIXED handling · cf9b6e7a
      Andrew Morton authored
      Patch from Rohit Seth
      
      ia64 reserves virtual address region 4 (any address which starts with 0x4)
      for huge pages.
      
      Apparently, for hardware reasons, we do not wish to allow mappings with
      other page sizes to appear in that region.
      
      This patch prevents the user from being able to place regular MAP_FIXED
      mappings into region 4 on ia64.  It is a no-op for ia32.

      [PATCH] ext2: clear ext3 htree flag on directories · dac80052
      Andrew Morton authored
      Forward port of a change which Ted made to 2.4's ext2.
      
      HTREE backwards compatibility patch.
      
      "I thought (and assumed) this patch had been applied to both the ext2 and
       ext3 filesystems in the 2.4 kernel.  It turns out it had only made it into
       the ext3 filesystem code.  This means that if an HTREE-enabled filesystem is
       mounted using ext2, it will corrupt the filesystem as far as e2fsck and an
       ext3 htree-enabled kernel is concerned.  (The corruption won't cause any
       data loss, but it will cause e2fsck and an ext3-htree kernel to omit a lot
       of warning messages.)"

      [PATCH] Don't panic if TSC is enabled and notsc is used · 0355478a
      Andrew Morton authored
      Patch from: john stultz <johnstul@us.ibm.com>
      
      The kernel will currently panic if it was built with CONFIG_X86_TSC and
      someone boots it with `notsc'.
      
      Change it to just print a warning.

      [PATCH] fix preempt-issues with smp_call_function() · a8dd6484
      Andrew Morton authored
      Patch from Thomas Schlichter <schlicht@uni-mannheim.de>
      
      Based on a patch from Dave Jones.
      
      It converts a large number of instances of:
      
      	smp_call_function(foo);
      	foo();
      
      into
      
      	on_each_cpu(foo);
      
      and in doing so fixes up the preempt-unsafeness of the first version.

      [PATCH] loop: Fix OOM and oops · 29da03f1
      Andrew Morton authored
      The loop driver takes a copy of the data which it is writing.  When this
      happens on the try_to_free_pages() path, loop can easily consume ALL memory
      and bio_copy() will fail to allocate a page.
      
      Loop forgets to check the bio_copy() return value and oopses.
      
      Fix this by dropping PF_MEMALLOC and throttling to the block writeout speed.
      
      The patch exports blk_congestion_wait() to modules for this.  This is a
      needed export: several filesystems have a "try to allocate and yield if it
      failed" loop and blk_congestion_wait() is a more appropriate way of
      implementing the sleep in this situation.
