      [PNP] remove DMA 0 restrictions · 29ffe2ad
      Adam Belay authored
      The original argument for blocking DMA 0 was to avoid conflicts with
      "memory refresh"  but such configurations are only found on very old
      8-bit systems that are likely not supported by the linux kernel. 
      This patch allows dma 0 to be assigned to PnP devices by default.  If
      for whatever reason dma 0 cannot be used, one can avoid allocating it
      by setting the pnp_reserve_dma= kernel parameter.

      [PNP] release card devices on probe failure · 3b4216cf
      Adam Belay authored
      When a driver's probe routine fails, it may not release all of the
      card devices it requested.  This patch allows the pnp layer to ensure
      that all devices claimed by the failing driver are released properly.

      Adam Belay authored
      Here's an updated patch that will correct the compile error when PROC

      moves the local proc functions to the local include file.  Thanks to
      Daniele Bellucci for finding the problem and contributing to this

      [PATCH] AS oops fix · 4e37508f
      Andrew Morton authored
      From: Nick Piggin <piggin@cyberone.com.au>
      
      If a request is merged with another, it sometimes has to be repositioned on
      the rbtree - you just do a delete then an add.  This is a quite uncommon
      case though.
      
      I changed the way adding works, so collisions must be handled by the caller
      instead of being dumbly fixed by the add routine.  Unfortunately the
      uncommon callers weren't handling it properly.

      [PATCH] zoran driver documentation fix · 598d1366
      Andrew Morton authored
      From: Ronald Bultje <rbultje@ronald.bitfreak.net>
      
      the zoran kernel driver is called 'zoran.o' in its CVS (historical thing, I
      don't know why), and it's called zr36067.o in the kernel tree.  The
      documentation in the kernel tree refers to zoran.o, though, which is (in
      the kernel tree) the driver for zr36120-based cards, rather than the driver
      for zr360x7-based cards.
      
      The attached patch fixes the documentation and makes it refer to
      zr36067.o instead.

      I saw a lockup where 2 cpus were stuck in sem_lock().  It seems like we can
      loop back to retry_undos with the lock held.  That path takes the lock so
      we will deadlock.

      Andrew Morton authored
      From: Anton Blanchard <anton@samba.org>
      
      If init_new_context fails we definitely do not want to call mmput, because
      that will call destroy_context against an uninitialised context.  Instead
      we should back out what we did in init_mm.  Fixes some weird failures on
      ppc64 when running a fork bomb.

      Fix fallout from Jens' insert_here removal.  Without it its possible that a
      request on the dispatch list is on the merge hash as well which is bad.  I
      don't _think_ this would happen in any code paths, but I haven't looked too
      closely.  It makes the API a bit less fragile anyway.

      [PATCH] x445: setup_ioapic_ids_from_mpc fix · 36a57256
      Andrew Morton authored
      From: James Cleverdon <jamesclv@us.ibm.com>
      
      32-way IBM x445s will have I/O xAPICs with IDs greater than 0xF (0x8 to 0xE
      isn't enough).  This breaks the code in setup_ioapic_ids_from_mpc.
      However, the entire unique ID check is unnecessary.  Only I/O APICs using
      the serial APIC bus need the unique numbers.  Those sending messages
      through the system bus simply don't use them.

      [PATCH] Incorrect value for SIGRTMAX · 58e1dd1e
      Andrew Morton authored
      From: Corey Minyard <minyard@acm.org>
      
      I was having a problem with signals with POSIX timers, and it turns out 
      that the value of SIGRTMAX is incorrect.  Remember that there is no
      signal 0, so the signals should go from 1-_NSIG.  However, SIGRTMAX is
      defined as (_NSIG-1) in all architectures.  The following patch fixes this.
      
      This define is only used in drivers/usb/core/devio.c and 
      kernel/posix-timers.c, and both are incorrect without this fix.  There's
      also no check for zero in posix-timers.c, that fix is part of the diff.
      
      Also, shouldn't do_sigaction() use this value instead of _NSIG?  It's
      not a big deal, but some architectures have different values for _NSIG
      and SIGRTMAX.

      [PATCH] NCR5380 timeout fix · 32ca1b05
      Andrew Morton authored
      From: Wagner_Volanin <fadinha.mail@terra.com.br>
      
      I have an old Genius Colorpage-SP2 SCSI scanner.  It is shipped with a
      MS-PNR 8bit ISA non-pnp proprietary SCSI card from Microtek.
      
      Although its chipset is a NCR53c400a, it wouldn't work with the appropriate
      driver, always accusing timeout, whatever settings I passed to it.
      
      Today I messed a little with the NCR5380.c file in drivers/scsi which is
      included by the g_NCR5380 driver and I couldn't understand one thing:
      
      Why the function NCR5380_poll_politely() returned the value 'r' on success
      if this value should be '0' case everything went ok...
      
      So I changed "return r;" to "return 0;" and after that my scanner worked
      fine, and was easily detected by SANE, without a single error message.  :)
      
      I have not the time to delve into the problem further, but I wanted to
      report this.  I couldn't find any counter-effects caused by changing these
      return values.

      [PATCH] hangcheck compile fix · ce7073a0
      Andrew Morton authored
      From: john stultz <johnstul@us.ibm.com>
      
      Since monotonic_clock() is not defined on every arch yet, this patch
      insures the hangcheck-timer module (currently the only user of
      monotonic-clock) is not built where it will not compile.
      
      I know, I know. Ideally monotonic_clock() would be implemented on all
      arches, but I've just not had the time.  If any of the non x86/x86-64
      folks feel bored, drop me a line.  It'd be a fairly easy project.

      Nobody told me that the failure to export these (like their block

      use larger device numbers without them.  So...this patch exports the new

      [PATCH] access_ok is likely · 2c2f8449
      Andrew Morton authored
      From Manfred
      
      While trying to figure out why sysv msg is around 30% slower than pipes for
      data transfers I noticed that gcc's autodetection (3.2.2) guesses the
      "if(access_ok())" tests in uaccess.h wrong and puts the error memset into the
      direct path and the copy out of line.
      
      So tell the compiler that access_ok() is likely to be true.

      [PATCH] Summit sub-arch: Make logical IDs independent of BIOS numbering scheme · 33479170
      Andrew Morton authored
      From: James Cleverdon <jamesclv@us.ibm.com>
      
      In forthcoming IBM x445 systems, the physical APIC ID will not follow the
      simple rule laid out by Intel and encoded into xapic_phys_to_log_apicid.
      (The BIOS code that sets IDs doesn't work right above 16 CPUs if HT is turned 
      on, so for > 16-way the BIOS will disable HT and repack the physical CPUs
      into APIC clusters.)
      
      Anyway, it's a good idea to make the APIC code more independent of any
      particular BIOS numbering scheme.  This patch allocates logical IDs based on
      how many CPUs have already been onlined in a particular APIC cluster.

      From: Erik Andersen <andersen@codepoet.org>
      
      When someone specifies "init=" to select an alternative binary to run
      instead of /sbin/init, argv[0] is not set correctly.  This is a problem for
      programs such as busybox that multiplex applications based on the value of
      argv[0].  For example, even if you specify init=/bin/sh" on the kernel
      command line, busybox will still receive "/sbin/init" as argv[0] and will
      therefore run init rather than /bin/sh...
