<mingo@elte.hu> (02/02/20 1.371)
        - export vmalloc_to_page().

<torvalds@home.transmeta.com> (02/02/20 1.369.2.4)
        Get rid of non-working and unused "uvirt_to_bus()".
        
        Fix up vmalloc_to_page() and callers (argument is a kernel
        virtual address ie should be a "void *")

<rmk@flint.arm.linux.org.uk> (02/02/20 1.369.1.9)
        Preempt support and fix ARM build for thread_info changes

<thockin@sun.com> (02/02/20 1.369.5.1)
        Link status detection fix for natsemi net driver.
        
        Apparently, the LSTATUS bit of BMSR latches low until a management read. 
        This causes ETHTOOL_GLINK to report no-link on the first read after the
        link is connected.  (damned QA people catch dumb stuff like this KNOWING
        I'll have to fix it).  This patch just forces GLINK to mdio_read() twice.

<miles@megapathdsl.net> (02/02/20 1.369.2.5)
        Update rivafb for kdev_t changes in early 2.5.x series.

<rmk@flint.arm.linux.org.uk> (02/02/20 1.369.1.10)
        Add extra ARM help texts to arch/arm/Config.help, update some other
        help texts.

<rmk@flint.arm.linux.org.uk> (02/02/20 1.369.1.11)
        Documentation for user space ARM alignment trap handler describing
        its modes of operation.

<rmk@flint.arm.linux.org.uk> (02/02/20 1.369.1.12)
        Fix a bug where a user-generated unaligned load could read or write kernel
        data.

<elenstev@mesatop.com> (02/02/20 1.369.6.2)
        Correct typo in pcmcia net drivers help text.

<elenstev@mesatop.com> (02/02/20 1.369.6.3)
        Add some missing help texts to drivers/net/Config.help.

<EdV@macrolink.com> (02/02/20 1.369.2.6)
        This patch corrects PCI device id in pci_ids.h for Oxford Semi OX16PCI952
        PCI/dual 16950 UART chip, and adds this entry to pci.ids.  I downloaded the
        datasheet today and verified that 9521 is the correct device id.

<mikep@linuxtr.net> (02/02/20 1.369.6.4)
        Janitor patch for olympic tokenring driver, to replace the
        save_flags/cli/restore flags sequence with spin_locks.

<greg@kroah.com> (02/02/20 1.369.7.2)
        usb uhci.c:
                - added usb_get_urb() and usb_put_urb() logic

<greg@kroah.com> (02/02/20 1.369.7.3)
        usb usb-ohci.c:
                - added usb_put_urb() and usb_get_urb() logic

<greg@kroah.com> (02/02/20 1.369.7.4)
        usb usb-uhci.c:
                - added usb_put_urb() and usb_get_urb() logic.

<martin@mdiehl.de> (02/02/20 1.369.7.5)
        usb hub:
                - fix problem with us not delaying for any ammount of time after a new device
                  has been powered up, as the USB spec indicates should happen.

<johannes@erdfelt.com> (02/02/20 1.369.7.6)
        [PATCH] uhci.c, one more toggle fix
         
        This patch fixes another toggle bug and reverts the previous bogus
        patch which caused compile warnings.
        
        It also adds a quick comment explaining the criteria.

<johannes@erdfelt.com> (02/02/20 1.369.7.7)
        [PATCH] uhci.c, interrupt unlink in completion
        
        This patch fixes a bug where an interrupt URB is unlinked in the drivers
        completion handler and we'll try to resubmit it anyway.

<johannes@erdfelt.com> (02/02/20 1.369.7.8)
        [PATCH] uhci.c, fix pci dma ordering issue
        
        There was a bug where we unmap the PCI DMA mapping and then sync the
        data afterwards. This reverses the ordering as well as insures we don't
        unmap the region more than once.

<johannes@erdfelt.com> (02/02/20 1.369.7.9)
        uhci.c didn't work well with USB storage. It would tend to stall
        relatively quickly and sometimes locked up the system. It usually only
        took me a couple of tries ripping a CD to reproduce the problem.
        
        I took a long hard look at the locking in uhci.c and decided to clean
        it up, fixing a couple of bugs along the way as well as documenting the
        locking strategy.
        
        With this patch applies, where I could only rip a CD a couple of times
        before causing problems, I was able to rip a CD 12,000 times in a row
        successfully, before I stopped it. Not a single error :)

<greg@kroah.com> (02/02/20 1.369.7.10)
        usb config.help:
                - removed an unneeded header.  Thanks to Jeff Garzik for pointing this out.

<greg@kroah.com> (02/02/20 1.369.7.11)
        usb vicam driver:
                - compile time fixes

<mmcclell@bigfoot.com> (02/02/20 1.369.7.12)
        usb ov511 driver:
                - update to version 1.49
                  (with a bit of merge foo from greg)

<jt@hpl.hp.com> (02/02/21 1.369.6.5)
        Update (ancient) wireless net drivers netwave_cs, wavelan,
        and wavelan_cs to new wireless API.

<jgarzik@mandrakesoft.com> (02/02/21 1.369.6.6)
        Update wireless net drivers wavelan and wavelan_cs to directly
        use spin_[un]lock_irq{save,restore}, instead of defining static
        inline functions to do the same thing (but possibly in a non-portable
        way).

<mingo@elte.hu> (02/02/21 1.373)
        cleanups, speedups and fixes. Added support for non-current set_cpus_allowed().

<mingo@elte.hu> (02/02/21 1.374)
        - make i_mmap and i_mmap_shared a list.h list
        -
         make vma->vm_next_share and vma->vm_pprev_share
          a proper list.h list as well.

<torvalds@penguin.transmeta.com> (02/02/21 1.369.1.15)
        make rd.c compile again

<Andries.Brouwer@cwi.nl> (02/02/21 1.369.1.16)
        [PATCH] imm.c
        
        2.5.5 Oopses at boot time with a disk in a zipdrive.
        With this patch all is fine. I have not read the
        patch, certainly not checked it for correctness,
        just observed that it works for me.
        I think the author is Rich Baum.
        
        Andries

<reiser@namesys.com> (02/02/21 1.369.1.17)
        [PATCH] 2.5 dropping unneded lock precense check.
        
        After BKL was moved from the VFS into the filesystem's methods in the lookup
        call, we do not need to check BKL is actually held (we know it is not).
        This patch patch removes unneeded lock_depth check.
        Without this patch reiserfs cannot be used on SMP.

<Ballabio_Dario@emc.com> (02/02/21 1.369.1.18)
        [PATCH] PATCH: scsi driver update for 2.5.5
        
        Here enclosed patch for eata.c, eata.h, u14-34f.c, u14-34f.h
        to be applied to lk-2.5.5.
        
        eata.c:
               + Remove any reference to virt_to_bus().
               + Fix pio hang while detecting multiple HBAs.
               + Fixed a board detection bug: in a system with
                 multiple ISA/EISA boards, all but the first one
                  were erroneously detected as PCI.
        
        u14-34f.c:
               + Remove any reference to virt_to_bus().
               + Fix pio hang while detecting multiple HBAs.

<hirofumi@mail.parknet.co.jp> (02/02/21 1.369.1.19)
        [PATCH] Insufficient validity check of fat_read_super() <2>
        
        This patch add the validity check of 2 values (fats, reserved). These
        values must not be 0.
        
        OGAWA Hirofumi <hirofumi@mail.parknet.co.jp>

<rml@tech9.net> (02/02/21 1.369.1.20)
        [PATCH] proper lseek locking in ALSA, take 3
        
        The attached patch implements proper locking in ALSA lseek methods.
        Note ALSA has 3 lseek implementations, but only:
        
                sound/core/info.c :: snd_info_entry_llseek()
        
        requires locking.  I wrapped the function in the BKL.  According to
        Jaroslav Kysela the gus_mem_proc method is only called from above.  The
        third lseek, in hwdep.c, clearly doesn't need locking.  Without this
        patch, the above lseek is not safe.
        
                Robert Love

<rml@tech9.net> (02/02/21 1.369.1.21)
        [PATCH] add lseek changes to fs porting guide
        
        Al updated Documentation/filesystems/porting with 2.5 changes but there
        is no mention of lseek.  The following patch, against 2.5.5, adds lseek
        to the list of functions that no longer are called with the BKL.
        
                Robert Love

<akpm@zip.com.au> (02/02/21 1.369.1.22)
        [PATCH] .text.exit linkage errors
        
        A forward-port of all the .text.exit fixes which went into
        2.4.   Also contains a couple of s/MINOR/minor/ changes.

<andersg@0x63.nu> (02/02/21 1.369.1.24)
        [PATCH] missing chunk in lvm-fixes in 2.5.5
        
        the lvm-patch that went into 2.5.5 missed the changes in lvm.h and is
        still not compileable. This patch adds those changes. The kernel i'm
        running right now has this patch and /var and /home on lvm.

<mingo@elte.hu> (02/02/23 1.376)
        
        - new, less intrusive and faster migration method:
        
        /*
         * This is how migration works:
         *
         * 1) we queue a migration_req_t structure in the source CPU's
         *    runqueue and wake up that CPU's migration thread.
         * 2) we down() the locked semaphore => thread blocks.
         * 3) migration thread wakes up (implicitly it forces the migrated
         *    thread off the CPU)
         * 4) it gets the migration request and checks whether the migrated
         *    task is still in the wrong runqueue.
         * 5) if it's in the wrong runqueue then the migration thread removes
         *    it and puts it into the right queue.
         * 6) migration thread up()s the semaphore.
         * 7) we wake up and the migration is done.
         */

<mingo@elte.hu> (02/02/23 1.377)
        - cleanup patch from Hugh Dickins, fix up drivers to use vmalloc_to_page() instead of local hacks of uvirt_to_kva(). (and related fixes.)

<viro@math.psu.edu> (02/02/25 1.375.1.1)
        [PATCH] Re: [BUGFIX] handling bad inodes in 2.4.x kernels (fwd)
        
        here's much simpler fix (both 2.4 and 2.5):

<torvalds@penguin.transmeta.com> (02/02/25 1.379)
        Update kernel version and defconfig

<viro@math.psu.edu> (02/02/25 1.380)
        [PATCH] (1/3) fs/super.c cleanups
        
        * missing yield() added to grab_super() (on failure exit).  Without
          that we have a nasty race - if get_sb_bdev() happens just before
          we grab ->s_umount in kill_super(), we are going to have
          get_sb_bdev() spinning indefinitely long without yielding CPU,
          so that kill_super() could make progress (and break the loop).
        
        * in kill_super() code that does actual superblock shutdown is
          wrapped in if (sb->s_root) {}.  That condition is true for
          all old callers of kill_super(), so we don't change existing
          behaviour.
        
        * instances of deactivate_super()/remove_super() (after failed
          call of foo_fill_super()) are replaced with
                up_write(&s->s_umount);
                kill_super(s);
          - now it becomes legitimate (kill_super() works on such guys and
          does exactly what we want).

<viro@math.psu.edu> (02/02/25 1.381)
        [PATCH] (2/3) fs/super.c cleanups
        
        Now remove_super() is called only from kill_super().  We move
        the code that closes device/drops reference to filesystem type
        from remove_super() into its caller.

<viro@math.psu.edu> (02/02/25 1.382)
        [PATCH] (3/3) fs/super.c cleanups
        
        Preparation to adding new method:
         new helper - shutdown_super().  It is cut from kill_super() and
         it had absorbed all actions done with superblock contents -
         now kill_super(s) is simply
        
                struct file_system_type *fs = s->s_type;
                if (!deactivate_super(s))
                        return;
                        shutdown_super(s);
                put_filesystem(fs);
        
         and shutdown_super() is going to become a method.

<viro@math.psu.edu> (02/02/25 1.384)
        [PATCH] net/wanrouter/wan{proc,main}.c crapectomy
        
                Patch below does the following:
        
        *       removes dead code from wanproc.c.   When file looks like
        #ifdef LINUX_2_4
        <800 lines>
        #else
        <900 lines>
        #endif
                there's no excuse for keeping all that junk around.
        *       switches wanproc.c to use of seq_file
        *       removes dead code from wanmain.c (again, dead == never seen by cc1).
        *       fixes indentation in both
        *       removes buttloads of trailing spaces in these files, while we are
                at it.
        
        See if it's OK with you...

        [PATCH] kdev_t search/replaces.
        
        First batch of various kdev_t related changes that have accumulated on
        linux-kernel, and some that got sent directly to me after you dropped them.
        
        Some of these need additional fixes to make them work, Some of them
        even to make them compile, but this is one step forward..
        
        I have bio-related fixes for some of these also, I'll push those seperately.

        [PATCH] un'fix' NCR scsi driver.
        
        Linus,
         Current driver in your tree has been 'fixed' by someone without
        understanding just how broken it was. Numerous fixes were done in 2.4
        after the 2.5 split by Alan.
        
        This patch reverts the damage the driver does in your tree, and brings
        Alan's 2.4 bits over instead. Downside: It doesn't compile.
        Upside: It doesn't pretend to work and corrupt data, and at least
        is the right base for people to start fixing.

        [PATCH] later DMI scan.
        
        This moves the dmi scan to an earlier stage so that we can trap issues
        such as the various laptops that don't like enabling APIC.
        It's likely to be useful for trapping other similar early-boot problems.

        [PATCH] Patch - sharing RTC timer between kernel and user space (2nd)
        
        This patch to allow using of RTC timer inside the kernel space.  We can
        use the RTC timer as timing source for ALSA sequencer. Patch by Takashi.
        
        The patch adds these three functions and one structure to rtc.h and
        rtc.c:
        
        typedef struct rtc_task {
               void (*func)(void *private_data);
               void *private_data;
        } rtc_task_t;
        
        int rtc_register(rtc_task_t *task);
        int rtc_unregister(rtc_task_t *task);
        int rtc_control(rtc_task_t *t, unsigned int cmd, unsigned long arg);
