-Subject: [PATCH v2] mtd: m25p80: Add support for ESMT F25L32PA
-
-This flashchip is used in D-Link DIR-610 A1 router board 
-and maybe several others, yet is not kernel upstream.
-
-So add support for it according to datasheet [0], making it easier
-to support other boards using this flashchip in the future.
-
-Changelog v2:
- - Better description
- - Datasheet link at the bottom, similar to other patches.

-Subject: [PATCH] MIPS: decompressor: fix build failure on memcpy() in
- decompress.c
-
-The decompress.c file includes linux/kernel.h which causes the following
-inclusion chain to be pulled:
-linux/kernel.h ->
-	linux/dynamic_debug.h ->
-		linux/string.h ->
-			asm/string.h
-
-We end up having a the GCC builtin + architecture specific memcpy() expanding
-into this:
-
-void *({ size_t __len = (size_t n); void *__ret; if
-(__builtin_constant_p(size_t n) && __len >= 64) __ret = memcpy((void *dest),
-(const void *src), __len); else __ret = __builtin_memcpy((void *dest), (const
-void *src), __len); __ret; })
-{
- [memcpy implementation in decompress.c starts here]
- int i;
- const char *s = src;
- char *d = dest;
-
- for (i = 0; i < n; i++)
-  d[i] = s[i];
- return dest;
-}
-
-raising the following compilation error:
-arch/mips/boot/compressed/decompress.c:46:8: error: expected identifier or '('
-before '{' token
-
-There are at least three possibilities to fix this issue:
-
-1) define _LINUX_STRING_H_ at the beginning of decompress.c to prevent
-   further linux/string.h definitions and declarations from being used, and add
-   an explicit strstr() declaration for linux/dynamic_debug.h
-
-2) remove the inclusion of linux/kernel.h because we actually use no definition
-   or declaration from this header file
-
-3) undefine memcpy or re-define memcpy to memcpy thus resulting in picking up
-   the local memcpy() implementation to this compilation unit
-
-This patch uses the second option which is the less intrusive one.

-Subject: [PATCH 11/12] USB: EHCI: add ignore_oc flag to disable overcurrent
- checking
-
-This patch adds an ignore_oc flag which can be set by EHCI controller
-not supporting or wanting to disable overcurrent checking. The EHCI
-platform data in include/linux/usb/ehci_pdriver.h is also augmented to
-take advantage of this new flag.

-Subject: bridge: allow receiption on disabled port
-
-When an ethernet device is enslaved to a bridge, and the bridge STP
-detects loss of carrier (or operational state down), then normally
-packet receiption is blocked.
-
-This breaks control applications like WPA which maybe expecting to
-receive packets to negotiate to bring link up. The bridge needs to
-block forwarding packets from these disabled ports, but there is no
-hard requirement to not allow local packet delivery.
