      of: Fix the section mismatch warnings. · 5b624118
      由 Xiubo Li 提交于 
      In tag next-20140407, building with CONFIG_DEBUG_SECTION_MISMATCH
enabled, the following WARNING is occured:

WARNING: drivers/built-in.o(.text.unlikely+0x2220): Section mismatch
in reference from the function __reserved_mem_check_root() to the
function .init.text:of_get_flat_dt_prop()
The function __reserved_mem_check_root() references
the function __init of_get_flat_dt_prop().
This is often because __reserved_mem_check_root lacks a __init
annotation or the annotation of of_get_flat_dt_prop is wrong.

WARNING: vmlinux.o(.text.unlikely+0xb9d0): Section mismatch in reference
from the function __reserved_mem_check_root() to the (unknown reference)
.init.data:(unknown)
The function __reserved_mem_check_root() references
the (unknown reference) __initdata (unknown).
This is often because __reserved_mem_check_root lacks a __initdata
annotation or the annotation of (unknown) is wrong.

This is cause by :
'drivers: of: add initialization code for dynamic reserved memory'.

      sym53c8xx_2: Set DID_REQUEUE return code when aborting squeue · fd1232b2
      由 Mikulas Patocka 提交于 
      This patch fixes I/O errors with the sym53c8xx_2 driver when the disk
returns QUEUE FULL status.

When the controller encounters an error (including QUEUE FULL or BUSY
status), it aborts all not yet submitted requests in the function
sym_dequeue_from_squeue.

This function aborts them with DID_SOFT_ERROR.

If the disk has full tag queue, the request that caused the overflow is
aborted with QUEUE FULL status (and the scsi midlayer properly retries
it until it is accepted by the disk), but the sym53c8xx_2 driver aborts
the following requests with DID_SOFT_ERROR --- for them, the midlayer
does just a few retries and then signals the error up to sd.

The result is that disk returning QUEUE FULL causes request failures.

The error was reproduced on 53c895 with COMPAQ BD03685A24 disk
(rebranded ST336607LC) with command queue 48 or 64 tags.  The disk has
64 tags, but under some access patterns it return QUEUE FULL when there
are less than 64 pending tags.  The SCSI specification allows returning
QUEUE FULL anytime and it is up to the host to retry.

      drivers: net: xen-netfront: fix array initialization bug · 810d8ced
      由 Vincenzo Maffione 提交于 
      This patch fixes the initialization of an array used in the TX
datapath that was mistakenly initialized together with the
RX datapath arrays. An out of range array access could happen
when RX and TX rings had different sizes.
