      ARM: 5957/1: ARM: RealView SD/MMC Card detection and write-protect using GPIOLIB · b56ba8aa
      Colin Tuckley authored
      The switch to using GPIOLIB broke the sd/mmc card detection on the
      RealView development boards if GPIO_PL061 was not selected.
      This patch selects GPIO_PL061 if GPIOLIB is selected.
      The sense of the return value from mmc_status has also changed
      and is corrected.

      sfc: Change falcon_probe_board() to fail for unsupported boards · e41c11ee
      Ben Hutchings authored
      The driver needs specific PHY and board support code for each SFC4000
      board; there is no point trying to continue if it is missing.
      Currently unsupported boards can trigger an 'oops'.

      When we finish processing ASCONF_ACK chunk, we try to send
      the next queued ASCONF.  This action runs the sctp state
      machine recursively and it's not prepared to do so.

      sctp: fix to calc the INIT/INIT-ACK chunk length correctly is set · a8170c35
      Wei Yongjun authored
      When calculating the INIT/INIT-ACK chunk length, we should not
      only account the length of parameters, but also the parameters
      zero padding length, such as AUTH HMACS parameter and CHUNKS
      parameter. Without the parameters zero padding length we may get
      following oops.

      sctp: per_cpu variables should be in bh_disabled section · 81419d86
      Vlad Yasevich authored
      Since the change of the atomics to percpu variables, we now
      have to disable BH in process context when touching percpu variables.

      sctp: fix potential reference of a freed pointer · 0c42749c
      Vlad Yasevich authored
      When sctp attempts to update an assocition, it removes any
      addresses that were not in the updated INITs.  However, the loop
      may attempt to refrence a transport with address after removing it.

      sctp: avoid irq lock inversion while call sk->sk_data_ready() · 561b1733
      Wei Yongjun authored
      sk->sk_data_ready() of sctp socket can be called from both BH and non-BH
      contexts, but the default sk->sk_data_ready(), sock_def_readable(), can
      not be used in this case. Therefore, we have to make a new function
      sctp_data_ready() to grab sk->sk_data_ready() with BH disabling.
      
      =========================================================
      [ INFO: possible irq lock inversion dependency detected ]
      2.6.33-rc6 #129
      ---------------------------------------------------------
      sctp_darn/1517 just changed the state of lock:
       (clock-AF_INET){++.?..}, at: [<c06aab60>] sock_def_readable+0x20/0x80
      but this lock took another, SOFTIRQ-unsafe lock in the past:
       (slock-AF_INET){+.-...}
      
      and interrupts could create inverse lock ordering between them.
      
      other info that might help us debug this:
      1 lock held by sctp_darn/1517:
       #0:  (sk_lock-AF_INET){+.+.+.}, at: [<cdfe363d>] sctp_sendmsg+0x23d/0xc00 [sctp]
