      [PATCH] USB: disable usb device endpoints in more places · 9dfb0ad1
      David Brownell authored
      This patch touches the most significant places in usbcore
      that need to respond to configuration change events:
      
        - set_interface changes altsettings; affects endpoints
          in both new and old settings (but not other endpoints).
      
        - set_configuration; affects every endpoint
      
      The endpoints get disabled, flushing hardware state
      reliably.  This resolves two FIXMEs here, part of one
      in OHCI (ed_get) and all of one in EHCI (qh_append_tds).
      
      Not many drivers currently use these code paths, but
      now they should start to work properly.

      I got a similar SMP report recently, but without info about
      which clause was failing -- which is a key clue, thanks!!
      
      The COMPLETING state is used only while a QH is being
      scanned for completed TDs.  (Think CPU-0 irq handler.)
      Looking at the handful of places that call the routine
      reporting the BUG(), a couple seem like they could make
      trouble with multiple CPUs in the driver.

      Hmm, so if some other URB gets queued in that window,
      it'll get trashed?  Unlikely .. the clean fix would be
      making the status endpoint have a real URB queue.
      
      I combined your suggested change with two others:
      (a) protect the status-unlink and control completion
          handlers against IRQs [ the cases Duncan noted]
      (b) use mod_timer to retrigger the timer, instead of the
          heavy weight path.

      Update ppc for mingo's do_fork changes.  Together with the pmac compile
      fixes this allows me to stay at the bleeding edge with my my ibook..

      [PATCH] revert sysfs non-fix · a193c746
      Andrew Morton authored
      I completely misread this code and there was no bug.  In fact yesterday's fix
      broke it.  Revert.

      [PATCH] apply_alternatives() fix · f69ca779
      Andrew Morton authored
      From: Andi Kleen <ak@suse.de>
      
      There is some assembly code in setup.c which doesn't explicitly set its
      section.  It comes after a C function which is marked __init.  The compiler
      does not reset the section after such C functions.  The assembly code is
      going into .text.init.
      
      That's the wrong section.  We get oopses modprobing sctp and, with Manfred's
      unmap-free-pages debug patch we get oopses modprobing e100.ko.  In
      apply_alternatives().
