      [ARM PATCH] 1761/1: Remove SA1111_PCI_FAKEDEV (take 2) · 0b5a9b4c
      Deepak Saxena authored
      Patch from Deepak Saxena
      
      Follows your suggestion and also removes the #ifdef around
      pci_unmap_addr and friends. Since pci.h should only be getting
      included if PCI is enabled by PCI drivers and core, we shouldn't
      need the NOP version.

      [ARM PATCH] 1759/1: Add ARM925 support, updated · 04275968
      Tony Lindgren authored
      Patch from Tony Lindgren
      
      The following patch adds the ARM925 processor support.
      
      This patch is based on the proc-arm925.S in 2.4 kernel, and it has been
      modified to be more like the ARM926 support in the 2.6 kernel, except for
      the cache flushing and initialization. Also, this patch fixes the
      writeback cache flushing for most part.
      
      There are still some issues with writeback cache flushing with devices 
      using direct memory access, such as USB OHCI. It is recommended to use
      the writethrough instead if using USB. This is the default for OMAP-1510.
      OMAP-1610 does not have these issues, as it uses ARM926 core.
      
      This patch includes the update for the processor functions to be armv4t 
      instead armv5t as suggested here:

      [PATCH] fixes to ColdFire/5407 startup code · 06d1514e
      Greg Ungerer authored
      Correct the cache setup bits for the 5407. This enables the write
      buffers properly (despite what the previous comment said). This
      combined with fixed cache flushing code provides a nice performance
      boost on the 5407.
      
      Also fix the ROMfs setup to only move the ROMfs region if it is actually
      configured.

      [PATCH] mark ftape un-removable · 9c27c441
      Andrew Morton authored
      From: Christoph Hellwig <hch@lst.de>
      
      I've just grepped over the tree for reamining MOD_INC_USE_COUNT users, and
      ftape is a really horrible one, it relies on MOD_{INC,DEV}_USE_COUNT in the
      most horrible places + it's own bookkepping and the <= 2.4 may unload
      hooks.  And although I don't have the hardware I can guarantee it doesn't
      work as expected.
      
      So let's just remove the module_exit handler and mark it unremovable, if
      someone wants to fix up ftape later it's fine with me, but it's a really
      scary driver..

      [PATCH] tuner driver fixes · 7541c77e
      Andrew Morton authored
      From: Gerd Knorr <kraxel@bytesex.org>
      
      "options tuner type=2" is just there for historical reasons and should
      only be used/needed if the main driver doesn't allow to configure the
      tuner type.  I'm not sure whenever I can remove that altogether without
      breaking anything.  There are several users of the tuner module, some
      outside the standard kernel tree ...
      
      > >         if (type < TUNERS) {
      > > +               t->type = type;
      > >                 printk("tuner: type forced to %d (%s) [insmod]\n",
      > >                        t->type,tuners[t->type].name);
      > >                 set_type(client,type);
      
      That is wrong, it will break in other corner cases, it may cause the
      set_type() function not doing the initializations.
      
      The prink can also be dropped because set_type does that too.  The patch
      below removes that.  It also makes the kernel messages a bit more verbose
      and adds support for two new tuners.

      [PATCH] Fix sprintf modifiers in usr/gen_init_cpio.c for cygwin · 499104b6
      Andrew Morton authored
      From: Pragnesh Sampat <pragnesh.sampat@timesys.com>
      
      The file initramfs_data.cpio is slightly different when generated on
      cygwin, compared to linux, which causes the kernel to panic with the
      message "no cpio magic" (See Documentation/early-userspace/README).
      
      The problem in cpio generation is due to the difference in sprintf
      modifiers on cygwin.  The code uses "%08ZX" for strlen of a device node.
      printf man pages discourages "Z" and has 'z' instead.  Both of these are
      not available on cygwin sprintf (at least some versions of cygwin).  The
      net result of all of this is that the generated file literally contains
      "ZX" and then the strlen after that and messes up that 110 offset etc.  The
      file is 516 bytes long on the system that I tested and on linux it is 512
      bytes.
      
      The fix below just uses "%08X" for that field.

      [PATCH] Inefficient TLB flush fix · 68d01416
      Andrew Morton authored
      From: Martin Hicks <mort@wildopensource.com>
      
      This is a patch based on one that Jack Steiner sent to the ia64 list in
      November.  The original thread can be found at:
      
      http://marc.theaimsgroup.com/?l=linux-ia64&m=106869606922555&w=2
      
      I created the little wrapper function that was requested.  I think the only
      other arch, other than ia64, that doesn't at least include asm-generic/tlb.h
      is arm.
      
      
      Something appears broken in TLB flushing on IA64 (& possibly other
      architectures).  Functionally, it works but performance is bad on systems
      with large cpu counts.
      
      The result is that TLB flushing in exit_mmap() is frequently being done via
      IPIs to all cpus rather than with a "ptc" instruction or with a new
      context..

      [PATCH] ide-tape: remove obsolete onstream support · 725fb82e
      Andrew Morton authored
      From: Willem Riede <wrlk@riede.org>
      
      
      The onstream drives, be they scsi, atapi, ieee1394 or usb, are supported by the
      osst driver.  When the drives were new, code was introduced in ide-tape
      independently, but never really maintained since.  There are issues with the
      drives I found and dealt with in osst, that ide-tape doesn't address.
      
      So this code in ide-tape is both redundant and imperfect.  I assumed from
      http://marc.theaimsgroup.com/?l=linux-kernel&m=107550547613846&w=2 that there
      was buy in for removing it.
      
      When this patch is applied, ide-tape will refuse to attach to an onstream DI
      drive, and will write to syslog to use ide-scsi + osst instead.

      [PATCH] Fix race in epoll_ctl(EPOLL_CTL_MOD) · 2328d92a
      Andrew Morton authored
      From: Davide Libenzi <davidel@xmailserver.org>
      
      A potential race can happen in epoll_ctl(EPOLL_CTL_MOD) where an event can
      happen in between f_op->poll() and the lock on ep->lock (we cannot call
      f_op->poll() inside a lock, and the f_op->poll() callback does not carry
      any info at the current time - missing wake_up_info() already ;).  In that
      case the event would be removed.  We can easily leave the event inside the
      ready list and have the ep_send_events() logic do the job for us at later
      time.  (Thanks to david.lee@teracruz.com for reporting the thing, since it
      shouldn't have been a nice one ;)

      [PATCH] Fix __release_region() race · 43630c2c
      Andrew Morton authored
      From: MAEDA Naoaki <maeda.naoaki@jp.fujitsu.com>
      
      I am testing PCI hot-plug in 2.6.2 kernel, but sometimes a struct resource
      tree in kernel/resource.c was broken if multiple hot-plug requests are
      issued at the same time.
      
      The reason is lots of drivers call release_region() on hot removal, and
      __release_region(), which is invoked by release_region() macro, changes the
      tree without holding a writer lock for resource_lock.
      
      I think __release_region() must hold a writer lock as well as
      __request_region() does.
      
      A following patch fixes the issue in my environment.

      While I was stress-testing NFS/XFS on 2.6.1/2.6.2-rc, I found that
      sometimes my "dd" would exit with:
      
      	#  dd if=/dev/zero bs=4096 > /mnt/file
      	dd: writing `standard output': Invalid argument
      	1100753+0 records in
      	1100752+0 records out
      
      After adding some debug printk's to the server and client code and some
      tcpdump-ing, I found that the NFSERR_INVAL was returned by nfsd_commit on
      the server.
      
      Turns out that the "offset" argument is off_t instead of loff_t.  It isn't
      used at all (unfortunately), but it _is_ checked for sanity, so that's
      where the error came from.
