      [ARM PATCH] 1380/1: Big-Endian support for jiffies · e4923829
      Russell King authored
      Patch from Deepak Saxena
      
      jiffies is defined as pointing to jiffies_64 for backwards comptability (I think, not 100% sure why we don't just use jiffies_64 everywhere?). On BE systems, we need to point to the upper 4 bytes of jiffies_64 or we will never get past calibrate_delay. This is what is done in PPC, SH, and other big endian architectures.

      [PATCH] printk size_t qualifier confusion · 7f939798
      Andrew Morton authored
      My printf manpage says:
      
             z      A  following  integer  conversion  corresponds to a
                    size_t or ssize_t argument. (Linux libc5 has Z with
                    this meaning. Don't use it.)
      
      And the opengroup spec says
      
      z Specifies that a following d , i , o , u , x , or X conversion specifier
        applies to a size_t or the corresponding signed integer type argument; or
        that a following n conversion specifier applies to a pointer to a signed
        integer type corresponding to a size_t argument.
      
      
      yet our vsnprintf implementation has
      
      				/* 'z' support added 23/7/1999 S.H.    */
      				/* 'z' changed to 'Z' --davidm 1/25/99 */
      
      
      I guess the path of least surprise is to support both.  gcc-3.2.1 doesn't
        seem to care.

      [PATCH] fix adaptec diagnostics for ppc64 · 61b8dae6
      Andrew Morton authored
      The return type of sizeof() is size_t.  On many architectrues size_t is
      unsigned long, and may not be printed with %d.  Use %Zu instead.

      [PATCH] OSS CS4232 locking fixes · 2b8a659c
      Andrew Morton authored
      Patch from: Peter Waechtler <pwaechtler@mac.com>
      
      Addresses BUGME bug #331.  "OSS CS4232 nasty spinlock printks on boot"
      
      The locking in some OSS modules is really lousy.
      Because save_flags/cli/restore_flags could be used recursivly - the
      programmers pushed the locking too far the lower level.
      
      Because on ISA cards the register sets are usually multiplexed
      you had to write to an address latch and then access the data port
      in an "atomic" manner.
      
      I suggest removing the locking from ad_read/ad_write +
      ad_{enter|leave}_MCE and clamping the locks wherever the functions
      are called. I hope the attached patch does that correctly.
      
      Yes, I don't like all the timeout loops while holding the locks:
      high chances that a cpu is spinning in interrupt context :(

      [PATCH] fix fadvise64() return type · f979631f
      Andrew Morton authored
      Patch from: David Mosberger <davidm@napali.hpl.hp.com>
      
      Please remember to declare the return-type of syscall stubs as "long".
      On 64-bit platforms, it's generally necessary to ensure that the
      entire 64-bit return value is valid (and can be checked against
      negative values).

      Andrew Morton authored
      This driver is calling down into scsi_register with local interrupts
      disabled.  scsi_register performs blocking allocations, starts kernel

      [PATCH] sunrpc dcache cleanup · b72d7dcb
      Andrew Morton authored
      Patch from Dipankar Sarma <dipankar@in.ibm.com>
      
      All fs should be using dcache APIs to manipulate dcache hash lists.  This is
      in line with the dcache cleanup patch (dcache_rcu-1) from Maneesh that Linus
      accepted.  This seems like a reasonable cleanup.  One change though, we don't
      need to grab dcache_lock while deleting dentries from the private list and
      __d_drop() should suffice here.

      [PATCH] disassociate_ctty SMP fix · 01ffc65c
      Andrew Morton authored
      Patch from Rik van Riel <riel@conectiva.com.br>
      
      the following patch, against today's BK tree, fixes a small
      SMP race in disassociate_ctty.  This function gets called
      from do_exit, without the BKL held.
      
      However, it sets the *tty variable before grabbing the bkl,
      then makes decisions on what the variable was set to before
      the lock was grabbed, despite the fact that another process
      could modify its ->tty pointer in this same function.

      assuming dev_t is unsigned generates a warning on ppc64.  Cast it.

      [CPUFREQ] add support for cpufreq governors. · 2e585809
      Dave Jones authored
      More bits from Dominik.
      
      Most cpufreq drivers (in fact, all except one, longrun) or even most
      cpu frequency scaling algorithms only offer the CPU to be set to one
      frequency. In order to offer dynamic frequency scaling, the cpufreq
      core must be able to tell these drivers of a "target frequency". So
      these specific drivers will be transformed to offer a "->target"
      call instead of the existing "->setpolicy" call. For "longrun", all
      stays the same, though.
      
      How to decide what frequency within the CPUfreq policy should be used?
      That's done using "cpufreq governors". Two are already in this patch
      -- they're the already existing "powersave" and "performance" which
      set the frequency statically to the lowest or highest frequency,
      respectively. At least two more such governors will be ready for
      addition in the near future, but likely many more as there are various
      different theories and models about dynamic frequency scaling
      around. Using such a generic interface as cpufreq offers to scaling
      governors, these can be tested extensively, and the best one can be
      selected for each specific use.
      
      Basically, it's the following flow graph:
      
      CPU can be set to switch independetly    |         CPU can only be set
            within specific "limits"           |       to specific frequencies
      
                                       "CPUfreq policy"
                      consists of frequency limits (policy->{min,max})
                           and CPUfreq governor to be used
                               /                    \
                              /                      \
                             /                       the cpufreq governor decides
                            /                        (dynamically or statically)
                           /                         what target_freq to set within
                          /                          the limits of policy->{min,max}
                         /                                \
                        /                                  \
              Using the ->setpolicy call,              Using the ->target call,
                  the limits and the                    the frequency closest
                   "policy" is set.                     to target_freq is set.
                                                        It is assured that it
                                                        is within policy->{min,max}

      [ARM] Better handling of bad IRQ implementations. · ea28cbc6
      Russell King authored
      There are edge triggered interrupt controllers around where the
      "enable" control is before the edge detection.  This means that
      we must keep the interrupts enabled, even when disable_irq() is
      in effect, and mark such interrupts for later processing.
      
      To make matters worse, some of these interrupt controllers do not
      provide any method to re-trigger the interrupt.  We are unable
      to call the handler direct from enable_irq() since we may be
      in an IRQ-protected context.
      
      Therefore, we add such interrupts to a list of pending interrupts,
      which we process at the next hardware interrupt.
