      powerpc/pseries: Make 32-bit MSI quirk work on systems lacking firmware support · f1dd1531
      Brian King authored
      Recent commit e61133dd added support
      for a new firmware feature to force an adapter to use 32 bit MSIs.
      However, this firmware is not available for all systems. The hack below
      allows devices needing 32 bit MSIs to work on these systems as well.
      It is careful to only enable this on Gen2 slots, which should limit
      this to configurations where this hack is needed and tested to work.
      
      [Small change to factor out the hack into a separate function -- BenH]

      Benjamin Herrenschmidt authored
      This moves the quirk itself to pci_64.c as to get built on all ppc64
      platforms (the only ones with a pci_dn), factors the two implementations
      of get_pdn() into a single pci_get_dn() and use the quirk to do 32-bit
      MSIs on IODA based powernv platforms.

      powerpc: Context switch more PMU related SPRs · 59affcd3
      Michael Ellerman authored
      In commit 9353374b "Context switch the new EBB SPRs" we added support for
      context switching some new EBB SPRs. However despite four of us signing
      off on that patch we missed some. To be fair these are not actually new
      SPRs, but they are now potentially user accessible so need to be context
      switched.

      We use two flags, one to indicate an invalidation is needed after
      creating a new entry and one to indicate an invalidation is needed
      after removing an entry. However we were testing the wrong flag
      in the remove case.

      drivers/crypto/nx: Fixes for multiple races and issues · 1ad936e8
      Kent Yoder authored
      Fixes a race on driver init with registering algorithms where the
      driver status flag wasn't being set before self testing started.
      
        Added the cra_alignmask field for CBC and ECB modes.
      
        Fixed a bug in GCM where AES block size was being used instead of
      authsize.
      
        Removed use of blkcipher_walk routines for scatterlist processing.
      Corner cases in the code prevent us from processing an entire
      scatterlist at a time and walking the buffers in block sized chunks
      turns out to be unecessary anyway.
      
        Fixed off-by-one error in saving off extra data in the sha code.
      
        Fixed accounting error for number of bytes processed in the sha code.

      be2net: bug fix on returning an invalid nic descriptor · 950e2958
      Wei Yang authored
      In function be_get_nic_desc(), it will go through the descriptor array
      returned from f/w. By comparing the desc_type field, it determines whether
      there is a nic descriptor in the array or not. In the case of no nic
      descriptor, this function should return NULL.
      
      The code may return an invalide descriptor, when there is no nic descriptor
      in the array and the desc_count is less than MAX_RESOURCE_DESC. In this case,
      even there is no nic descriptor, it will still return the lase descriptor
      since the i doesn't equal to MAX_RESOURCE_DESC.
      
      This patch fix this issue by returning the descriptor when find it and return
      NULL for other cases.

      Eric Dumazet authored
      commit 3853b584 ("xps: Improvements in TX queue selection")
      introduced ooo_okay flag, but the condition to set it is slightly wrong.
      
      In our traces, we have seen ACK packets being received out of order,
      and RST packets sent in response.
      
      We should test if we have any packets still in host queue.

       "Here are a number of tiny USB bugfixes / new device ids for 3.10-rc2
      
        The majority of these are USB gadget fixes, but they are all small.
        Other than that, some USB host controller fixes, and USB serial driver
        fixes for problems reported with them.
      
        Also hopefully a fixed up USB_OTG Kconfig dependancy, that one seems
        to be almost impossible to get right for all of the different
        platforms these days."

      xfrm: properly handle invalid states as an error · 497574c7
      Timo Teräs authored
      The error exit path needs err explicitly set. Otherwise it
      returns success and the only caller, xfrm_output_resume(),
      would oops in skb_dst(skb)->ops derefence as skb_dst(skb) is
      NULL.

      virtio_net: enable napi for all possible queues during open · e4166625
      Jason Wang authored
      Commit 55257d72 (virtio-net: fill only rx
      queues which are being used) only does the napi enabling during open for
      curr_queue_pairs. This will break multiqueue receiving since napi of new queues
      were still disabled after changing the number of queues.
      
      This patch fixes this by enabling napi for all possible queues during open.

      tcp: bug fix in proportional rate reduction. · 35f079eb
      Nandita Dukkipati authored
      This patch is a fix for a bug triggering newly_acked_sacked < 0
      in tcp_ack(.).
      
      The bug is triggered by sacked_out decreasing relative to prior_sacked,
      but packets_out remaining the same as pior_packets. This is because the
      snapshot of prior_packets is taken after tcp_sacktag_write_queue() while
      prior_sacked is captured before tcp_sacktag_write_queue(). The problem
      is: tcp_sacktag_write_queue (tcp_match_skb_to_sack() -> tcp_fragment)
      adjusts the pcount for packets_out and sacked_out (MSS change or other
      reason). As a result, this delta in pcount is reflected in
      (prior_sacked - sacked_out) but not in (prior_packets - packets_out).
      
      This patch does the following:
      1) initializes prior_packets at the start of tcp_ack() so as to
      capture the delta in packets_out created by tcp_fragment.
      2) introduces a new "previous_packets_out" variable that snapshots
      packets_out right before tcp_clean_rtx_queue, so pkts_acked can be
      correctly computed as before.
      3) Computes pkts_acked using previous_packets_out, and computes
      newly_acked_sacked using prior_packets.

       - Fix a build error if <linux/printk.h> is included without

       - Cleanup and fix the damage done by the generic idle loop patch.
       - A kprobes fix that brings the MIPS code in line with what other
         architectures are for quite a while already.
       - Wire up the native getdents64(2) syscall for 64 bit - for some reason
         it was only for the compat ABIs.  This has been reported to cause an
         application issue.  This turned out bigger than I meant but the wait
         instruction support code was driving me nuts.
