      [TCP]: Fix TCP header misalignment · 21df56c6
      Herbert Xu 提交于
      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 提交于
      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 提交于
      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 提交于
      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.

      dirty page balancing: Get rid of broken unmapped_ratio logic · 8c086340
      Linus Torvalds 提交于
      This code harks back to the days when we didn't count dirty mapped
      pages, which led us to try to balance the number of dirty unmapped pages
      by how much unmapped memory there was in the system.
      
      That makes no sense any more, since now the dirty counts include the
      mapped pages.  Not to mention that the math doesn't work with HIGHMEM
      machines anyway, and causes the unmapped_ratio to potentially turn
      negative (which we do catch thanks to clamping it at a minimum value,
      but I mention that as an indication of how broken the code is).
      
      The code also was written at a time when the default dirty ratio was
      much larger, and the unmapped_ratio logic effectively capped that large
      dirty ratio a bit.  Again, we've since lowered the dirty ratio rather
      aggressively, further lessening the point of that code.
