      [CPUFREQ] More powernow-k7 hardening. · 6322fd9d
      Dave Jones authored
      Even with the previous fixes, a stress test of rapidly changing speeds in a loop locked
      up my test laptop just after a day. Making the errata 5 workaround unconditional
      (previously it was only for certain steppings) seems to have cured it. It's now been
      running the stress test for nearly two days without a problem.

      [CPUFREQ] Fix ACPI P-State driver. · 88d91a82
      Dave Jones authored
      from Dmitry Torokhov.
      
      I have the following problems with ACPI P-States driver:
      
      - It crashes because it tries to switch CPU speed without registering cpufreq
      driver first but acpi_processor_set_performance calls cpufreq_notify_transition.
      
      - When testing for capable CPUs it skips all online ones so for my single CPU
      notebook it can't activate at all.
      
      - If a processor does not support throttling then it will say that "limit"
      interface is not supported even after activating performance control.
      
      The patch below should fix these issues. It also adds some info messages since
      /proc/acpi/processor/*/performance interface is marked obsolete but i still
      would like to see if P-states were recognized during boot.

      [CPUFREQ] kill cpufreq_driver export. · fcb1f22e
      Dave Jones authored
      From Dominik Brodowski.
      This removes the special export of cpufreq_driver for proc_intf.c. Instead,
      the behaviour of /proc/cpufreq previous of Greg's class re-write is back:
      the check whether cpufreq_driver is loaded is done within cpufreq_cpu_get

      When scaling upwards, we need to change the voltage before the frequency.
      When scaling downwards, the opposite.
      This may fix some of the hangs people have been seeing when jumping
      from a low frequency to a very high frequency.

      [PATCH] Fix raid1 handling of writing to multiple devices. · 1e23fe7d
      Neil Brown authored
      When raid1 writes, it needs to schedule writes to some number
      of devices, and when all writes have completed, the r1_bio
      structure that holds it all together must be freed.
      However we must make sure not to free it before all devices
      have been considered for submitting writes to.
      
      This happens in two places: when submitting a normal write request
      and when submiting a write as part of resync.
      
      This patch makes both these places:
        the same
        simpler
        more correct.

      [PATCH] allow thread_info to be allocated as part of task_struct · 7df5cefd
      David Mosberger authored
      This re-organizes the thread info allocations a bit, so that
      architectures like ia64 that want to allocate the thread_info structure
      as part of the task structure allocation can do so.
      
      The bulk of the patch is adding the "tsk" information to the thread
      info allocator (ignored by all non-ia64 architectures), and switching
      the order of the allocators to make this all possible.

      [PATCH] ext3: fix deadlock in journal_create() · d62b7983
      Andrew Morton authored
      From: Mark Fasheh <mark.fasheh@oracle.com>
      
      journal_create() is called under down_write(s_umount) on the mount path.  But
      it calls fsync_bdev(), which wants down_write(s_umount).
      
      Change journal_create() to run sync_blockdev() instead.  Just to write out
      the new journal's blocks.

      [PATCH] hugetlbfs: mount options and permissions · 07b71f8c
      Andrew Morton authored
      From: "Seth, Rohit" <rohit.seth@intel.com>
      
      This patch enables system administrators to more flexibly assign read/write
      permissions to files in hugetlbfs.  Mount options are added which will
      specify the uid, gid and mode of the filesystem's root directory.
      
      This patch also enables super users to do chown/chgrp on files in hugetlbfs.
      
      Also included in this patch is the support for uid, gid and mode command line
      options for mount command for hugetlbfs.
      
      The following mount options are added to hugetlbfs:
      
      	uid=value gid=value mode=value
      
      The values may be specified in hex (0xNNN), decimal or octal (0NNN).

      [PATCH] reiserfs support for blocksizes other than 4096 bytes · 1e559269
      Andrew Morton authored
      From: Oleg Drokin <green@namesys.com>
      
      This patch allows reiserfs to support blocksizes from 1024 bytes and up to
      PAGE_CACHE_SIZE.  Also it fixes two glitches that prevent reiserfs from
      working correctly in case if PAGE_CACHE_SIZE is bigger than blocksize.
      
      Originally this patch was created by Edward Shushkin and Vladimir Saveliev,
      and then it was adapted to modern 2.4 and 2.5 by me.
      
      Also people should be aware that 1024 bytes blocksize is not very good thing
      as tree grows very fast.  mkreiserfs is able to create filesystems with
      different blocksizes for quite a while already (-b switch).

      [PATCH] reiserfs option parser fix and ability to pass · b743d13b
      Andrew Morton authored
      From: Oleg Drokin <green@namesys.com>
      
      This patch adds support for remounting taking into account all extra options
      you may want to pass it.  (by Jeff Mahooney).
      
      Also it reworks the parser to correctly deal with mutually exclusive options.
      Now whatever option was specified last will take an effect.
      
      - If you pass more than one jdev= option, the error will be reported and
        mount/remount refused.
      
      - If you pass incorrect alloc= suboptions, the mount/remount will fail.
        (it did not before).
      
      - nolargeio now actually looks at its argument.  Argument is expected to be
        numeric.  If it is zero, default io size is set to 128k (default setting),
        if it is non-zero, default io size is set to PAGE_SIZE.

      [PATCH] Fix generic_file_write() again. · b7651add
      Andrew Morton authored
      From: "Milton D. Miller II" <miltonm@realtime.net>
      
      The code at present has a small problem: when a fault is encountered we will
      run commit_write() to cover the amount of data which was successfully copied
      in from userspace.
      
      But filemap_copy_from_user() may have zeroed out some more of the page.  So
      pagecache now has zeroes and the buffer_head which represents those zeroes is
      not dirtied.  So a subsequent eviction and re-read of the file in the window
      beyond the faulting offset will return the file's old contents and not the
      zeroes.
      
      So we change filemap_copy_from_user_iovec() to have the same behaviour as the
      non-iovec filemap_copy_from_user(), and ensure that the commit_write() covers
      the parts of the page which copy_from_user() zeroed out.

      [PATCH] Graceful failure in devfs_remove() · 2632cc57
      Andrew Morton authored
      From: Pavel Roskin <proski@gnu.org>, via Christoph Hellwig <hch@infradead.org>
      
      It's already the second time that I encounter a kernel panic in the same
      place.  When devfs_remove() is called on a non-existent file entry, the
      kernel panics and I have to reboot the system.
      
      First time it was unregistering of pseudoterminals.  This time it's
      ide-floppy module that doesn't register devfs entries if the media is absent
      but still tries to unregister them.  The bug in ide-floppy will be reported
      separately.
      
      The point of this message is that the failure in devfs_remove() is possible,
      especially with rarely used drivers.  Secondly, is not fatal enough to
      justify an immediate panic and reboot.  Thirdly, devfs misses a chance to
      tell the user what's going wrong.

      [PATCH] remove unsafe BUG_ON() · 82980ce2
      Andrew Morton authored
      From: Hugh Dickins <hugh@veritas.com>
      
      PageDirty BUG_ON in __remove_inode_page is, and always has been, unsafe for
      SMP or preemption: truncation may be racing against unmapping's
      set_page_dirty in zap_pte_range (amongst a few other possibilities).
      !PageUptodate error in __set_page_dirty_buffers is unsafe then too.

      [PATCH] radio-cadet.c: remove unnecessary copy_to_user() · 2cb28602
      Andrew Morton authored
      From: Hollis Blanchard <hollisb@us.ibm.com>
      
      As pointed out by the Stanford checker, 'v' is not tainted.  The driver
      shouldn't be using copy_to_user() in cadet_do_ioctl() at all:
      
        cadet_do_ioctl() is being called by drivers/media/video/videodev.c:
        video_usercopy(), which has already copied the buffer 'arg' (aka 'v')
        into kernel space, and will copy it back after cadet_do_ioctl()
        returns.  So all the direct 'v' accesses are correct.

      [ARM] Convert platform devices to use platform_device · 4f00f1c2
      Russell King authored
      Since struct platform_device now has the ability to pass resources,
      defined by the platform to the device driver, we can now use this
      to handle platform specific devices.  One such instance is the
      StrongARM SA1111 companion chip, which can appear in various address
      spaces, and connected to different IRQ lines depending on how many
      cups of coffee the hardware designer had, the direction of the wind
      outside the designers office that day.
      
      We also convert some of the other StrongARM peripheral on-chip
      devices to use struct platform_device.
      
      ARM also provides a platform_add_devices() function which can be
      used by platform code to bulk-register a tabular set of platform
      devices.
