      [PATCH] fix oops at pmac_zilog rmmod'ing · b5afcdb2
      Benjamin Herrenschmidt authored
      From: Colin Leroy <colin@colino.net>
      
      rmmod'ing pmac_zilog currently oopses because uart_unregister_driver(),
      which nullifies drv->tty_driver, is called before uart_remove_one_port(),
      which uses said drv->tty_driver.
      
      The comment at top of uart_unregister_driver() specifically says we have
      to have removed all our ports via uart_remove_one_port() before.

      [PATCH] ppc64: syscall error test incorrect for 64 bits results · 6c90fb7d
      Benjamin Herrenschmidt authored
      The syscall return path on ppc64 checks if the error is between
      -LAST_ERRNO and 0, if it is, does the usual inversion along with
      setting a CR bit indicating to glibc that an error occured.
      
      However, we had an interesting bug where we used a 32 bits logica
      (unsigned) comparison, thus possibly doing false positives for
      valid 64 bits unsigned values whose low 32 bits happen to be in
      the error range.
      
      Fix that.

      [PATCH] Add BINFMT_MISC docs for Mono .NET-based binaries · 5f746471
      Felipe Alfaro Solana authored
      Just as there is documentation for BINFMT_MISC and Java bytecodes
      support, I thought it could be interesting to add documentation on how
      to add BINFMT_MISC support for directly running .NET ".exe" binaries
      using the Mono CLR.

      [PATCH] ppc32: More preempt fixes · 379092d2
      Benjamin Herrenschmidt authored
      This patch fixes more cases of possible preempt issue when testing
      MSR for FP or VEC bits and then doing giveup_fpu or giveup_altivec
      that I missed in my previous round of fixes (bk get helps before
      grepping ;)
      
      I also change the single step and program check exceptions to not
      re-enable interrupts right away on C code entry, it was useless and
      would cause interesting issues with preempt & xmon

      [PATCH] add missing <linux/config.h> · 1a336f5d
      Roman Zippel authored
      A few asm/types.h test a config variable without including
      <linux/config.h> first, which can e.g. cause different sector_t
      definitions. HFS fell victim to that and broke on ppc with CONFIG_LBD
      enabled. I scanned all asm/types.h and added <linux/config.h> as
      necessary.

      [PATCH] ppc64: Use full DART table on G5 · 9cfd4af7
      Olof Johansson authored
      This increases the DART table to use the full size.  We allocate a full
      16MB page anyway, so there's no difference in memory consumption. 
      
      Thanks to Ben for spotting this, it was left over from debugging...

      [PATCH] USB: Eliminate wait following interface unregistration · 98c81a17
      Greg Kroah-Hartman authored
      This patch from Alan Stern <stern@rowland.harvard.edu> fixes a bug in
      the current USB code that causes khubd to hang when a device is removed
      from the system, thereby preventing any future USB device changes (like
      adding or removing other devices) from happening.
      
      Both Andrew and I can easily duplicate this bug against the current -bk
      tree. 
      
      It's not a perfect fix, but it works for now, and I will spend the next
      week working on restructuring the code so this is handled properly.

      [SPARC32]: Rename cpuid functions · bedd4ac0
      Keith M. Wesolowski authored
      smp_processor_id is to be used when current_thread_info()->cpu is
      valid; i.e. almost always.  Early on or when setting that field,
      hard_smp_processor_id is used.  Clarify the distinction and only
      export to modules what's really needed.  smp_processor_id is not
      model-specific, so we no longer need btfixups for it.

      [PATCH] Remove <asm/setup.h> from cmdlinepart.c · 5d6e3d87
      Andrew Morton authored
      From: Bjorn Helgaas <bjorn.helgaas@hp.com>
      
      Remove include of <asm/setup.h> from cmdlinepart.c.  This is not be needed
      for i386 (it builds fine with this patch), and ia64 doesn't supply a
      setup.h.
      
      asm/setup.h contains a hodge-podge of stuff with no real
      consistency between architectures.  It appears to be
      included mainly by arch-specific drivers:
      	acsi (Atari disks)
      	amiflop (Amiga floppy)
      	z2ram (ZorroII ram disk)
      	amiserial (Amiga serial)
      	...
      and under arch-specific #ifdefs:
      	fbcon (under __mc68000__ or CONFIG_APUS)
      	fonts (ditto)
      	logo (CONFIG_M68K)
      	...

      [PATCH] Fix uninitialized data in EFI RTC /proc interface · 589df808
      Andrew Morton authored
      From: Bjorn Helgaas <bjorn.helgaas@hp.com>
      
      The problem is that we don't clear out the efi_time_t buffer before asking
      EFI to fill it in.  EFI doesn't always write the entire buffer (in
      particular, the alarm time only supports one second resolution, so the
      nanosecond field is often untouched).
      
      The effect is that 'cat /proc/driver/efirtc' shows garbage in the
      nanoseconds part of the alarm time, and sometimes artifacts like bogus
      alarm date and junk after the actual end of the text.

      [PATCH] selinux: check return value for receive node permission · 735c736e
      Andrew Morton authored
      From: James Morris <jmorris@redhat.com>
      
      This patch fixes a bug where the return value for a permission call is not 
      checked.
      
      The bug was introduced when I added some code in the following changeset:
      
      <http://linux.bkbits.net:8080/linux-2.5/diffs/security/selinux/hooks.c@1.19?nav=index.html|src/|src/security|src/security/selinux|hist/security/selinux/hooks.c>
      
      Code was added after this line:
      
      	err = avc_has_perm(isec->sid, node_sid, SECCLASS_NODE, node_perm, NULL, &ad);
      
      without adding an explicit check of 'err', which was previously returned
      from the function rather than being checked.  i.e. it would drop through
      to:
      
      	out:	
       		return err;
      
       	}
      
      With the new code added, err can (and typically would) be overwritten with 
      a successful value, causing the permission check to not deny permission if 
      needed.  The intended denial would have been logged.
      
      The patch below fixes this problem.

      [PATCH] adjuct cpu_khz in response to cpufreq changes · e9c7ac4a
      Andrew Morton authored
      From: john stultz <johnstul@us.ibm.com>
      
      This patch ensures that cpu_khz is adjusted on cpufreq notifications even
      when the tsc timesource is not in use.  It fixes the mostly cosmetic issue
      when using the ACPI PM timesource of /proc/cpuinfo not being properly
      updated when cpu frequency was lowered.

      Andrew Morton authored
      From: Martin Schwidefsky <schwidefsky@de.ibm.com>
      
      The purpose of this is to speed up system calls on s390.  I managed to
      squeeze about 65 cycles from each system call.  This improved e.g.  getpid()
      from 232 to 157 cycles.  As a nice side-effect it simplified the uaccess
      functions considerably.

      dasd device driver changes:
       - After a state change interrupt restart all running i/o on queue
         and reset device timer.
       - Improve some debug messages.
       - Lower timeout of reserve/release/steal_lock to 2 seconds.
       - Fix BIODASDPSRD ioctl.
       - Replace ro_flag, use_diag_flag and disconnect_error_flag words by bits.
       - Use BLKPG_DEL_PARTITION ioctl instead of a call to delete_partition because
         delete_partition is not an exported function. Since dasd_destroy_partitions
         can't do blkdev_get because dasd_open would fail, keep the block device
         open as long as partitions exist. This in turn requires a different
         approach to the open vs. offline race.
