Upstream changed the default rootfs to tmpfs when none has been passed
|
||||
to the kernel - this doesn't fit our purposes, so change it back.

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.

MIPS: allow disabling the kernel FPU emulator

This patch allows turning off the in-kernel Algorithmics

FPU emulator support, which allows one to save a couple of

precious blocks on an embedded system.

+ MyLoader is a bootloader which allows the user to define partitions

|

|

+ enable this option.
|

+
|

This patch allows the user to specify desired packet types (outgoing,
|
||||
broadcast, unicast, etc.) on packet sockets via setsockopt.
|
||||
This can reduce the load in situations where only a limited number
|
||||
of packet types are necessary
