      [PATCH] add FP exception mode prctl · fcc6fcc6
      Paul Mackerras authored
      This patch that adds a prctl so that processes can set their
      floating-point exception mode on PPC and on PPC64.  We need this
      because the FP exception mode is controlled by bits in the machine
      state register, which can only be accessed by the kernel, and because
      the exception mode setting interacts with the lazy FPU save/restore
      that the kernel does.

      [PATCH] printk from userspace · e1b19d6e
      Andrew Morton authored
      The patch allows userspace to issue printk's, via sys_syslog().
      
      The main use of this is within hpa's klibc - initial userspace needs a
      way of logging information and this API allows that information to be
      captured into the printk ringbuffer.  It ends up in /var/log/messages.
      
      Messages are truncated at 1024 characters by printk's vsprintf().
      
      Requires CAP_SYS_ADMIN.

      Make sure we delete devices from the driver list the iteration after we 
      detach them (so we can get a valid next pointer)

      [PATCH] random fixes · 5b1b229f
      Andrew Morton authored
      - I changed the sector_t thing in max_block to use davem's approach.
        I agree with Anton, but making it explicit doesn't hurt.
      
      - Remove a dead comment in copy_strings.
      
      Old stuff:
      
      - Remove the IO error warning in end_buffer_io_sync().  Failed READA
        attempts trigger it.
      
      - Emit a warning when an ext2 is mounting an ext3 filesystem.
      
        We have had quite a few problem reports related to this, mainly
        arising from initrd problems.  And mount(8) tends to report the
        fstype from /etc/fstab rather than reporting what has really
        happened.
      
      Fixes some bogosity which I added to max_block():
      
      - `size' doesn't need to be sector_t
      
      - `retval' should not be initialised to "~0UL" because that is
        0x00000000ffffffff with 64-bit sector_t.
      
      - Allocate task_structs with GFP_KERNEL, as discussed.
      
      - Convert the EXPORT_SYMBOL for generic_file_direct_IO() to
        EXPORT_SYMBOL_GPL.  That was only exported as a practicality for the
        raw driver.
      
      - Make the loop thread run balance_dirty_pages() after dirtying the
        backing file.  So it will perform writeback of the backing file when
        dirty memory levels are high.  Export balance_dirty_pages to GPL
        modules for this.
      
        This makes loop work a lot better - I suspect it broke when callers
        of balance_dirty_pages() started writing back only their own queue.
      
        There are many page allocation failures under heavy loop writeout.
        Coming from blk_queue_bounce()'s allocation from the page_pool
        mempool.  So...
      
      - Disable page allocation warnings around the initial atomic
        allocation attempt in mempool_alloc() - the one where __GFP_WAIT and
        __GFP_IO were turned off.  That one can easily fail.
      
      - Add some commentary in block_write_full_page()

      [PATCH] scaled writeback throttling levels · 5803a3a6
      Andrew Morton authored
      get_page_state() is showing up on profiles on some big machines.  It is
      a quite expensive function and it is being called too often.
      
      The patch replaces the hardwired RATELIMIT_PAGES with a calculated
      amount based on the amount of memory in the machine and the number of
      CPUs.

      [PATCH] fix ARCH_HAS_PREFETCH · 8e4f2fd3
      Andrew Morton authored
      include/linux/prefetch.h does a strange thing: if the arch doesn't have
      the prefectch functions, this header defines no-op version of them and
      then defines ARCH_HAS_PREFETCH.  So there's no way for mainline code to
      know if the architecture *really* has prefetch instructions.
      
      This information loss is unfortunate.  Examples:
      
      	for (i = 0; i < N; i++)
      		prefetch(foo[i]);
      
         Problem is, if `prefetch' is a no-op, the compiler will still
         generate an empty busy-wait loop.  Which it must do.  We need to
         know the truth about ARCH_HAS_PREFETCH to correctly elide that loop.
