+Upstream changed the default rootfs to tmpfs when none has been passed

+Subject: netfilter: conntrack: cache route for forwarded connections
+
+... to avoid per-packet FIB lookup if possible.
+
+The cached dst is re-used provided the input interface
+is the same as that of the previous packet in the same direction.
+
+If not, the cached dst is invalidated.
+
+For ipv6 we also need to store sernum, else dst_check doesn't work,
+pointed out by Eric Dumazet.
+
+This should speed up forwarding when conntrack is already in use
+anyway, especially when using reverse path filtering -- active RPF
+enforces two FIB lookups for each packet.
+
+Before the routing cache removal this didn't matter since RPF was performed
+only when route cache didn't yield a result; but without route cache it
+comes at higher price.
+
+Julian Anastasov suggested to add NETDEV_UNREGISTER handler to
+avoid holding on to dsts of 'frozen' conntracks.

+
+On a BCM4709 based device, I found that GMAC cores may be enabled at
+probe time, but only become usable after a full reset.
+Disable cores before re-enabling them to ensure that they are properly
+reset.

+
+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.

+
+Several DMA ops are no-op on many platforms, and the indirection through
+the mips_dma_map_ops function table is causing the compiler to emit
+unnecessary code.
+
+Inlining visibly improves network performance in my tests (on a 24Kc

+Subject: [PATCH 2/3] mtd: part: add generic parsing of linux,part-probe
+
+This moves the linux,part-probe device tree parsing code from
+physmap_of.c to mtdpart.c. Now all drivers can use this feature by just
+providing a reference to their device tree node in struct
+mtd_part_parser_data.

+Subject: [PATCH] usb: ehci-orion: fix probe for !GENERIC_PHY
+
+Commit d445913ce0ab7f ("usb: ehci-orion: add optional PHY support")
+added support for optional phys, but devm_phy_optional_get returns
+-ENOSYS if GENERIC_PHY is not enabled.
+
+This causes probe failures, even when there are no phys specified:
+
+[    1.443365] orion-ehci f1058000.usb: init f1058000.usb fail, -38
+[    1.449403] orion-ehci: probe of f1058000.usb failed with error -38
+
+Similar to dwc3, treat -ENOSYS as no phy.
+
+Fixes: d445913ce0ab7f ("usb: ehci-orion: add optional PHY support")

+Subject: [PATCH 1/3] uapi/kernel.h: glibc specific inclusion of sysinfo.h
+
+including sysinfo.h from kernel.h makes no sense whatsoever,
+but removing it breaks glibc's userspace header,
+which includes kernel.h instead of sysinfo.h from their sys/sysinfo.h.
+this seems to be a historical mistake.
+on musl, including any header that uses kernel.h directly or indirectly
+plus sys/sysinfo.h will produce a compile error due to redefinition of
+struct sysinfo from sys/sysinfo.h.
+so for now, only include it on glibc or when including from kernel
+in order not to break their headers.

+Subject: [PATCH 2/3] uapi/libc-compat.h: do not rely on __GLIBC__
+
+Musl provides the same structs as glibc, but does not provide a define to
+allow its detection. Since the absence of __GLIBC__ also can mean that it
+is included from the kernel, change the __GLIBC__ detection to
+!__KERNEL__, which should always be true when included from userspace.

+Message-Id: <1396868224-252888-2-git-send-email-manuel.lauss@gmail.com>
+
+This small patch makes the MIPS FPU emulator optional. The kernel
+kills float-users on systems without a hardware FPU by sending a SIGILL.
+
+Disabling the emulator shrinks vmlinux by about 54kBytes (32bit,
+optimizing for size).

+v4: rediffed because of patch 1/2, should now work with micromips as well
+v3: updated patch description with size savings.
+v2: incorporated changes suggested by Jonas Gorski
+    force the fpu emulator on for micromips: relocating the parts
+    of the mmips code in the emulator to other areas would be a
+    much larger change; I went the cheap route instead with this.
