      [PATCH] remove preempt_disable from pdflush · eb245678
      Robert Love authored
      It seems by the comments the statements were only there to prevent the
      thread from finding itself as TASK_RUNNING after a kernel preemption.
      Since we reverted to the original preemption behavior (which does not do
      that) it should be safe.  Looking over the code confirms - it seems to
      not be doing anything evil and is properly locked otherwise.

      [PATCH] One more fix for swsusp · ffab9e04
      Pavel Machek authored
      As andrew pointed out, it is bad idea to run_task_queue() when
      spinlock is held. This fixes it (only could be triggered by user
      pressing Magic-D). There's minor problem left where Magic-D could be
      delayed/ignored under high load. I'll either fix that or kill Magic-D
      support (with acpi, it is very easy to trigger swsusp by echo 4 >
      /proc/acpi/sleep, so magic key is probably not neccessary any more).

      [PATCH] get/put_cpu methods · 79eb6a12
      Robert Love authored
      This implements a get_cpu() and matching put_cpu() to safely hand out
      the current CPU to avoid preempt races.  Andrew and I have been bitching
      about the need for such a method.
      
      I also went ahead and replaced an example of current explicit
      preempt-off with the new methods, as a case in point.

      [PATCH] more suspend-to-{RAM,disk} fixes · 8e93dcc8
      Pavel Machek authored
      One more build fix, this time for !CONFIG_SOFTWARE_SUSPEND but
      CONFIG_ACPI:
      
      I've choosen this solution for now, as it is safest for ACPI people.
      I'll modify suspend.c so that freezing part can be included without
      whole suspend-to-disk support being included.

      [PATCH] suspend-to-{RAM,disk} · 542f96a5
      Pavel Machek authored
      Here's suspend-to-{RAM,disk} combined patch for
      2.5.17. Suspend-to-disk is pretty stable and was tested in
      2.4-ac. Suspend-to-RAM is little more experimental, but works for me,
      and is certainly better than disk-eating version currently in kernel.
      
      Major parts are: process stopper, S3 specific code, S4 specific
      code.

      kbuild: Restore build nr, improve vmlinux link · ea52ca1b
      Kai Germaschewski authored
      People relied on the build generation number to find out if they actually
      booted the right kernel, only incrementing it on config changes isn't
      enough for them. So this patch goes back to the old behavior, only done
      right this time:
      
      We now don't increment the generation number on every invocation of make, 
      but on every link of vmlinux. At the same time, this patch fixes the
      Makefile to only relink vmlinux if any of its prequisite object files
      (or the command line) changed. Incrementing the version number
      happens *after* we decided to relink vmlinux.

      kbuild: Regenerate include/linux/version.h only if necessary · 5b281f91
      Kai Germaschewski authored
      Before overwriting version.h, check if it actually changed - otherwise
      we will unnecessarily rebuild a lot of files, as e.g. module.h depends
      on version.h, and many files include module.h

      [PATCH] Update to srm_env.c driver (for Alpha arch.) · e0c8dbaa
      Jan-Benedict Glaw authored
      Hi Linus!
      
      Please apply this patch. It updates the srm_env.c driver (to access
      Alpha's SRM environment variables) to its current version (which is
      already included in up-to-date 2.4.x kernels).

      [PATCH] remaining cpu_has cleanups · ec66b46d
      Brian Gerst authored
      This patch cleans up the remaining direct tests against x86_capability.
            It moves the cpu_has_* macros to the more appropriate
      cpufeature.h.  It also introduces the cpu_has() macro to test features
      for individual cpus.

      [PATCH] usb-storage · eae28375
      Andries E. Brouwer authored
      Created the first of a series of usb-storage patches
      this afternoon. Please find it below or on ftp.XX.kernel.org
      under people/aeb/2.5.16-us-patch .
      It removes 5% of the usb-storage code, but should, if I made
      no mistake, not affect the behaviour of the code.
      
      (This is the introduction of raw_bulk.c to hold USB-bulk
      and scatter-gather code that was repeated three-five times
      in various drivers. The next patch is smartmedia.c.)

      [PATCH] bfs header move around + warning fix · 70e08a38
      Christoph Hellwig authored
      (Patch has been ACKed by the bfs maintainer)
      
      Now that bfs no more is included in the big unions in fs.h it makes
      sense to move the contents of bfs_fs_i.h and bfs_fs_sb.h to a bfs-private
      location.  I've created fs/bfs/bfs.h for that, also merging in bfs_defs.h.
      
      In addition I've changed si_imap to an unsigned long pointer as the bitops
      now use that type explicitly.

      This changes futex semantics to a simple "sleep if this address

      other primitives.  It also adds a timeout value.

      [PATCH] buffermem_pages removal (4/5) · 71e6cd0a
      Christoph Hellwig authored
      This is the most discussion-worthy patch of the series:  Change the
      meaning of si_meminfo->bufferram from "all pages in pagecache
      backed by block devices" to "all pages in pagecache".
      
      In the header/manpage is is documented as "Memory used by buffers",
      but as the buffercache is gone I think the new meaning fits the
      intention from pre-pagecache days much better.

      Christoph Hellwig authored
      This one is a bit more controveral as it may break stupid userlevel
      programs:  remove the 'Buffers' field from /proc/meminfo and make
      the Cached field show the full pagecache size instead of subtracting
      the block-device backed pages.
      
      All /proc/meminfo-using programs I have (free, top) still work fine.

      [PATCH] buffermem_pages removal (1/5) · e95bd965
      Christoph Hellwig authored
      With all work done by akpm in 2.5 Linus no more has a buffer cache
      in the traditional sense.  Still we try to keep estimates about
      what would be the buffer cache size by keeping the number of pages
      indexed by block device inodes.  This is broken not only because the
      old buffercache was also used for file data which is nowdays not
      hashed to block device inodes and thus makes every user of this data
      assume wrong numbers.  Second is is possible to use block device
      pages not through the buffer_head interface (i.e. userspace
      block device nodes, possibly JFS also soon).  In addition the atomic_t
      used for this bookkepping (buffermem_pages) causes cacheline bouncing
      on larger machines.
      
      This is the first patch of a series to get rid of it.  It removes the
      useless output of supposedly buffer pages in show_mem(), which is used
      by the magic sysrq key code.

      kbuild: Stop immediately on error · 5f044d28
      Kai Germaschewski authored
      This patch restores the previous behavior of stopping the build
      immediately on error (unless the -k option is given to make)
      
      Before this patch, we would do the echo command no matter if the
      compile failed, thus returning success always.
