      [PATCH] correct vm_page_prot on stack pages · 300c2652
      Andrew Morton authored
      From: David Mosberger <davidm@napali.hpl.hp.com>
      
      The patch below is needed to make it possible to map stack pages
      without execution permission (as we do on ia64).

      [PATCH] don't clear PG_uptodate on ENOSPC · 2accc2e3
      Andrew Morton authored
      If get_block() returns -ENOSPC __block_write_full_page() is currently
      clearing PG_uptodate.
      
      Tht doesn't make any sense - failure to allocate space (or an IO error) does
      not make the page not uptodate.  It will create pages which are dirty, mapped
      into pagetables and not uptodate, which is a nonsensical state.

      [PATCH] Fix deadlock with ext3+quota · 36b4f825
      Andrew Morton authored
      From: Jan Kara <jack@ucw.cz>
      
      Fixes a deadlock-causing lock-ranking bug between dqio_sem and
      journal_start().
      
      It sets up the needed infrastructure so that the quota code's sync_dquot()
      operation can call into ext3 and arrange for the transaction start to be
      nested outside the taking of dqio_sem.

      [PATCH] Remove flush_page_to_ram() · edf20d3a
      Andrew Morton authored
      From: Hugh Dickins <hugh@veritas.com>
      
      This patch removes the long deprecated flush_page_to_ram.  We have
      two different schemes for doing this cache flushing stuff, the old
      flush_page_to_ram way and the not so old flush_dcache_page etc. way:
      see DaveM's Documentation/cachetlb.txt.  Keeping flush_page_to_ram
      around is confusing, and makes it harder to get this done right.
      
      All architectures are updated, but the only ones where it amounts
      to more than deleting a line or two are m68k, mips, mips64 and v850.
      
      I followed a prescription from DaveM (though not to the letter), that
      those arches with non-nop flush_page_to_ram need to do what it did
      in their clear_user_page and copy_user_page and flush_dcache_page.
      
      Dave is consterned that, in the v850 nb85e case, this patch leaves its
      flush_dcache_page as was, uses it in clear_user_page and copy_user_page,
      instead of making them all flush icache as well.  That may be wrong:
      I'm just hesitant to add cruft blindly, changing a flush_dcache macro
      to flush icache too; and naively hope that the necessary flush_icache
      calls are already in place.  Miles, please let us know which way is
      right for v850 nb85e - thanks.

      [PATCH] remove the test for null waitqueue in __wake_up() · 831cbe24
      Andrew Morton authored
      I've had a warning in there for 4-5 months and it has never triggered.  I
      think it's safe to remove this test.

      [PATCH] Fix gen_rtc compilation error · a802b873
      Andrew Morton authored
      From: Geert Uytterhoeven <geert@linux-m68k.org>
      
      It updates include/asm-{generic,parisc}/rtc.h for the recent changes in
      drivers/char/genrtc.c and include/asm-{m68k,ppc}/rtc.h.
      
      get_rtc_time() now returns some RTC flags instead of a 0/-1 success/failure
      indicator.  These flags include:
      
         - RTC_BATT_BAD: RTC battery is bad (can be detected on PA-RISC)
         - RTC_24H: Clock runs in 24 hour mode
      
      Most of these flags are the same as drivers/char/rtc.c, but RTC_BATT_BAD is a
      new one.

      [PATCH] radix_tree_delete API improvement · ed49cb09
      Andrew Morton authored
      radix_tree_delete() currently returns 0 on success, -ENOENT if there was
      nothing to delete.
      
      But it is more useful to return the address of the deleted item on success
      and NULL if there was no matching item.  It can potentially save a
      lookup+delete operation.

      [PATCH] kobject hotplug fixes · 932fd605
      Andrew Morton authored
      - allocated storage `envp' was being leaked on an error path
      
      - kmalloc() returns void*, no need to cast it
      
      - don't return 0 from a void-returning function
      
      Greg has acked this patch.
