      [PATCH] smp_call_function doco fix · 57078435
      Rusty Russell authored
      Trivial patch update against 2.5.17:
      dipankar@in.ibm.com: smp_call_function change:
        My earlier patch fixed only i386. As per Dave Miller's suggestion,
        I have fixed smp_call_function for other smp architectures too.
      
        Description
        -----------
        Going by the documentation and use of _bh version of spin_lock(),
        smp_call_function() is allowed to be called from BH context,
        We can run into a deadlock with some locks if we do so.
        This because reader-writer locks can sometimes be used optimally
        by not disabling irqs while taking the reader side if only the
        reader side of the lock is taken from irq context.
      
              CPU #0                                CPU #1
      
              read_lock(&tasklist_lock)
                                               write_lock_irq(&tasklist_lock)
                                               [spins with interrupt disabled]
              [Interrupted by BH]
              smp_call_function() for BH
                   handler
                                               [ doesn't take the IPI]
      
        So, cpu #1 doesn't take the IPI and cpu #0 spinwaits
        for the IPI handler to start, resulting in a deadlock.
      
        The last time I looked, I couldn't see smp_call_function() being
        called from BH context anywhere. So, there is no immediate problem.
        However it seems right to correct the documentation and also not
        disable BH while taking the call lock since it isn't necessary.
        This patch does exactly that.
      
        Thanks

      [PATCH] sigio delivery fix · c1140e63
      Rusty Russell authored
      Stephen Rothwell <sfr@canb.auug.org.au>: fix for sigio delivery:
        Hi Linus,
      
        This patch means that we keep the upper 16 bits of the si_code
        field of the siginfo structure that is delivered with and SIGIOs.
        We need this so that the code that actually copies the siginfo_t
        out to user mode knows which part of the union to copy.  We currently
        get away with out this information because we always copy at least
        two ints worth of the union, but this s an ugly hack and I would
        like to tidy it up.
      
        Comments?

        Hello,
      
         It seems all Ethernet device drivers were bulk-converted to use the new
        common CRC functions.  I discovered declance used incorrect endianness to
        calculate the sum for its multicast filter and had a few alignment
        problems there.  I fixed these bugs in the MIPS/Linux CVS tree which is at
        2.4.18 now.  Here is the respective update for the official kernel.
      
         The bugs make the filter non-functional.  Please apply.

      Simplify linking/building objects in subdirectories · aa2ac864
      Kai Germaschewski authored
      New-style Makefiles have a nice way of declaring objects
      which need to be built either built-in or as modules:
      
              obj-$(CONFIG_EEPRO100) += eepro100.o
      
      However, handling objects in subdirectories, which need to be
      built and linked is not as nice:
      
              subdir-$(CONFIG_E100) += e100
      
              ifeq ($(CONFIG_E100),y)
                obj-y += e100/built-in.o
              endif
      
      This means we descend into the subdirectory when building
      vmlinux / modules, depending on CONFIG_XXX. When we are building
      vmlinux we also need to link whatever has been built in the
      subdirectory, so we add it to $(obj-y) at the appropriate place
      (link order is important).
      
      Now, the extension below allows to rewrite the second case into
      
               obj-$(CONFIG_E100) += e100/
      
      which looks much nicer ;-) Existing behavior is not changed, and the
      only prerequisite to using the extension above is that the O_TARGET in
      the subdir is named "built-in.o".

      [PATCH] split namei.h out of fs.h · 26d7de18
      Christoph Hellwig authored
      Currently fs.h is full of unrelated declarations and included in almost
      any source file. Thus it makes sense to spilt certain aspects out that are
      only used by few users.
      
      This patch starts with the namei/path lookup interface and splits it into
      <linux/namei.h> which is now directly included by the 24 files that actually
      need it.

      [PATCH] 2.5.17 IDE 66 · 6b4fef7a
      Martin Dalecki authored
       - Move ll_10byte_cmd_build to the only place where it's used: ide-cd.  The SCSI
         layer does have it's own implementation which additionally it's messing
         around with the hard_nr_sectors struct request value.  One should *not*
         provide "infrastructure" until its really used as such.
      
         If anywhere this should reside in a file called ATAPI.
      
       - Unfold the INIT_REQUEST macro from blk.h. This showed up plenty of duplicate
         checks for QUEUE_EMPTY. Clean them as well. Remove the over cautious
         major(CURRENT->rq_dev != MAJOR_NR) checks. During the last several years I
         never saw any report about it. Looking at the !CURRENT->bio it is clear that
         dereferencing NULL will provide the same kind of panic as the check.  Some
         comments around the code in question show nicely that indeed INIT_REQUEST
         was a good example of code obfuscation.
      
       - A short look at RQ_INACTIVE shows that it is only used inside the scsi.c file
         and during the removal of devices. This shows that the many checks for
         RQ_INACTIVE are not necessary. Looking closer even shows that some of them
         did happen before checks for an empty queue. Plenty of drivers didn't care
         about it and the CD-ROM ones should be handled properly, because the
         most common drivers would fail as well. Comments indicate that this
         was an leftover from 1.3 days...
