      [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).

      [PATCH] EATA driver fix · 030219ad
      Andrew Morton authored
      This driver is calling down into scsi_register with local interrupts
      disabled.  scsi_register performs blocking allocations, starts kernel
      threads, etc.  slab debugging gets offended by someone performing blocking
      operations with local interrupts disabled.

      [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.

      I have a whole bunch of silly compile warning fixes here, arising from
      building the kernel for a 64-bit target.  Some are trivial, some are genuine
      printk bugs.

      [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}

      [PATCH] x86-64 merge · d8f19f2c
      Andi Kleen authored
      This brings the x86-64 port uptodate in 2.5.60. Unfortunately I cannot
      test too much because i constantly get deadlocks in exit/wait in initscripts
      on SMP bootup. The kernel seems to still lose a lot of SIGCHLD. 2.5.59/SMP
      had the same problem. Uniprocessor and SMP kernel on UP seems to work.
      
      This patch only touches x86-64 specific files. It requires a few simple
      changes to arch independent files that I will send separately.
      
       - Fixed a lot of obsolete/misleading configure help texts.
       - Remove old bootblock disk loader and support fdimage target for syslinux
         instead (H. Peter Anvin)
       - Fix potential fpu signal restore problem on 32bit emulation.
       - Merge with 2.5.60 i386 (hugetlbfs, acpi etc.)
       - Some fixes for local apic disabled modus.
       - Beginngs of S3 ACPI wakeup from real-mode (not working yet, don't use)
       - Beginnings of NUMA/CONFIG_DISCONTIGMEM support for AMD K8 (work in progress,
         port from 2.4): clean up memory mapping at bootup, generalize bootmem etc.
       - Fix 64bit GS base reload problem and reenable (Karsten Keil)
       - Fix race with vmalloc accesses from interrupt handlers disturbing page fault/
         similar race for the debug handler (thanks to Andrew Morton)
       - Merge cpu access primitives with i386
       - Revert to private module list for now because putting modules
         nto vmlist triggered too many problems.
       - Some cleanups, removal of unneeded code.
       - Let early __get_free_pages see consistent pda
       - Preempt disabled for now because it is too broken right now
       - Signal handler fixes
       - Fix do_gettimeofday to be completely lockless and reenable vsyscalls
       - Optimize context switch path a bit (should be ported to i386)
       - Get thread_info via stack for better code
       - Don't leak pmd pages
       - Clean up hardcoded task stack sizes.
