      [PATCH] migration thread fix · 5cfceb83
      Robert Love authored
      Attached is a patch that disables interrupts while holding the rq_lock.
      This is certainly needed to prevent a race against the timer tick, as
      Erich Focht pointed out.

      - line ending white spaces squadron strikes back;
      - some fscked tabs are fixed. Nice           after longs        coding sessions.

      - new functions for LxDA mode: dscc4_tx_done() and dscc4_tx_quiescent();
      - dscc4_{rx/tx}_reset() should comply to errata sheet.

      - dscc4_do_action() now looks like the others event waiting loops (may be
        called from interrupt context however);
      - dscc4_start_xmit(): cosmetic before LxDA changes + mb() parano;
      - dscc4_clock_setting(): only one return point, thanks;
      - dscc4_priv() invocation removed from dscc4_xxx_settings;
      - minor cleanups.

      François Romieu authored
      - DEBUG_PARANOIA was bad. "if (debug > x) {" is nice;
      - state_check() now has only one return point;
      - try_get_rx_skb() cosmetic;
      - dscc4_rx_update() belongs to HOLD mode to LxDA changes;
      - dscc4_wait_ack_cec() behaves like dscc4_xpr_ack();
      - dscc4_rx_skb() refill logic is ready for LxDA mode and does everything
        to fulfill what its name suggests.
      - document some errata voodoo in dscc4_init_one();
      - dscc4_init_ring() should handle try_get_rx_skb() failure.

      François Romieu authored
      - dscc4_xpr_ack() busy waiting loop is modified so as to allow long
        delay without chewing too much cycles;
      - more errata sheet magic;
      - dscc4_set_clock() now has only one return point.

      - space after "if"'s and "while"'s were missing here and there. Now it's easier to read
        after some hours in front of a computer.

      François Romieu authored
      - dscc4_patch_register() turns into scc_patchl() and should now avoid an
        hardware bug quoted in errata sheet;
      - dscc4_init_registers() interface changes as any caller doesn't really need
        to poke into dscc4_dev_priv internal;
      - scc_{writel/readl}() are added to access some buggy behaving registers;
      - {read/write}l conversion to the previous functions
      - dscc4_do_tx() sneaks, sorry. Belongs to HOLD -> LxDA changes.

      [PATCH] stop NULL pointer dereference in __alloc_pages · 0cf094f4
      Martin J. Bligh authored
      This trivial patch will apply to both 2.4.19-pre7 and 2.5.8 with just line
      offsets. It stops us from following a NULL pointer in classzone in the case
      where there is a pgdat without a fully populated zone list (ie a node with
      no ZONE_NORMAL on an ia32 NUMA machine). Without this patch, ia32
      NUMA machines won't even boot - we dereference the classzone ptr
      a few lines further down (or try to ;-) ).

      [PATCH] pagecache locking bugfix · cff6ab5e
      Andrew Morton authored
      The bug which Anton found.  On the
      find_or_create_page->__find_lock_page path we're performing
      a read_unlock of an rwlock which is held for writing.
      
      The patch converts that to using a write_lock throughout.
      
      Which penalises find_lock_page() a bit.  If it shows up
      on profiles then we can clone __find_lock_page() and
      use read_lock()s, but for now I'd opt for saving the
      cache footprint.

      [PATCH] 2.5.8 IDE 38 · 43c1ab59
      Martin Dalecki authored
      - Fix typo in ide_cmd_ioctl().
      
      - Fix typo in cris driver.
      
      - Don't retry operations on medium errors. (pointed out by Eric Andersen).
      
      - Attach the no_io_32bit, io_32bit, no_unmask, unmask and slow fields to the
         ata_channel instead of the ata_device structure. They are a property of the
         channel and not just the devices attached to it. This allowed us to fix the
         set_io_32bit function by removing the CONFIG_BLK_DEV_DTC2278 conditional. In
         fact initialization shows that this is fixing many other host chipsets as
         well since all of them did expect sometimes particular values for those
         parameters in paralell on both drives attached to a channel but we where
         allowed to apply different values on a per drive basis.
      
      - The keep_settings flag is now unconditional and we don't mess with any
         channel parameters before drive reset. Some chipsets really really expect
         unconditionally that the tweaks they apply are always present and this wasn't
         honoured thus far! We are expecting the user to have good reasons for
         manually tweaking the settings.
      
      - Don't reset io_32bit in ata_pre_reset() unconditionally. There are chipsets
         out there which expect io_32bit to be *allways* enabled!
      
      - Remove many obsolete and nawadays just confusing documentation from ide.txt
