      [TCP]: Fix TCP header misalignment · 21df56c6
      Herbert Xu authored
      Indeed my previous change to alloc_pskb has made it possible
      for the TCP header to be misaligned iff the MTU is not a multiple
      of 4 (and less than a page).  So I suspect the optimised IPsec
      MTU calculation is giving you just such an MTU :)
      
      This patch fixes it by changing alloc_pskb to make sure that
      the size is at least 32-bit aligned.  This does not cause the
      problem fixed by the previous patch because max_header is always
      32-bit aligned which means that in the SG/NOTSO case this will
      be a no-op.
      
      I thought about putting this in the callers but all the current
      callers are from TCP.  If and when we get a non-TCP caller we
      can always create a TCP wrapper for this function and move the
      alignment over there.

      [NET]: Corrects a bug in ip_rt_acct_read() · 483b23ff
      Eric Dumazet authored
      It seems that stats of cpu 0 are counted twice, since
      for_each_possible_cpu() is looping on all possible cpus, including 0
      
      Before percpu conversion of ip_rt_acct, we should also remove the
      assumption that CPU 0 is online (or even possible)

      rt2x00: Request usb_maxpacket() once · b242e891
      Ivo van Doorn authored
      The usb max packet size won't change during the
      device's presence. We should store it in a
      variable inside rt2x00dev and use that.
      This should also fix a division error when the
      device is being hot-unplugged while a frame is
      being send out.

      x86: simplify "make ARCH=x86" and fix kconfig all.config · 6840999b
      Sam Ravnborg authored
      Simplify "make ARCH=x86" and fix kconfig so we again can set 64BIT in
      all.config.
      
      For a fix the diffstat is nice:
       6 files changed, 3 insertions(+), 36 deletions(-)
      
      The patch reverts these commits:
       - 0f855aa6 ("kconfig: add helper to set
         config symbol from environment variable")
       - 2a113281 ("kconfig: use $K64BIT to
         set 64BIT with all*config targets")
      
      Roman Zippel pointed out that kconfig supported string compares so
      the additional complexity introduced by the above two patches were
      not needed.
      
      With this patch we have following behaviour:
      
        # make {allno,allyes,allmod,rand}config [ARCH=...]
        option \ host arch      | 32bit         | 64bit
        =====================================================
        ./.                     | 32bit         | 64bit
        ARCH=x86                | 32bit         | 32bit
        ARCH=i386               | 32bit         | 32bit
        ARCH=x86_64             | 64bit         | 64bit
      
      The general rule are that ARCH= and native architecture takes
      precedence over the configuration.
      
      So make ARCH=i386 [whatever] will always build a 32-bit kernel
      no matter what the configuration says.  The configuration will
      be updated to 32-bit if it was configured to 64-bit and the
      other way around.
      
      This behaviour is consistent with previous behaviour so no
      suprises here.
      
      make ARCH=x86 will per default result in a 32-bit kernel but as
      the only ARCH= value x86 allow the user to select between 32-bit
      and 64-bit using menuconfig.

      x86: fix reboot with no keyboard attached · 05dfa35e
      Truxton Fulton authored
      Attempt to fix http://bugzilla.kernel.org/show_bug.cgi?id=8378
      
      Hiroto Shibuya wrote to tell me that he has a VIA EPIA-EK10000 which
      suffers from the reboot problem when no keyboard is attached.  My first
      patch works for him:
      
        http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=59f4e7d572980a521b7bdba74ab71b21f5995538
      
      But the latest patch does not work for him :
      
        http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=8b93789808756bcc1e5c90c99f1b1ef52f839a51
      
      We found that it was necessary to also set the "disable keyboard" flag in
      the command byte, as the first patch was doing.  The second patch tries to
      minimally modify the command byte, but it is not enough.
      
      Please consider this simple one-line patch to help people with low end VIA
      motherboards reboot when no keyboard is attached.  Hiroto Shibuya has
      verified that this works for him (as I no longer have an afflicted
      machine).
      
      
      Additional discussion:
      
      Note that original patch from Truxton DOES
      disable keyboard and this has been in main tree since 2.6.14, thus it must have
      quite a bit of air time already.
      
      http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.14.y.git;a=commit;h=59f4e7d572980a521b7bdba74ab71b21f5995538
      
      Note that he only mention "System flag" in the description and comment, but
      in the code, "disable keyboard" flag is set.
      
        outb(0x14, 0x60);       /* set "System flag" */
      
      In 2.6.23, he made a change to read the current byte and then mask the flags,
      but along this change,  he only set the "System flag" and dropped the setting
      of "disable keyboard" flag.
      
      http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.23.y.git;a=commit;h=8b93789808756bcc1e5c90c99f1b1ef52f839a51
      
         outb(cmd | 0x04, 0x60); /* set "System flag" */
      
      So my request is to restore the setting of disable keyboard flag which has been
      there since 2.6.14 but disappeared in 2.6.23.
