Commit caacf05e causes big drop of UDP loop back performance. The cause of the regression is that we do not cache the local output routes. Each time we send a datagram from unconnected UDP socket, the kernel allocates a dst_entry and adds it to the rt_uncached_list. It creates lock contention on the rt_uncached_lock. Reported-by:

Add 6 new devices and one modified device, based on information from laptop vendor Windows drivers. Sony provides a driver with two new devices using a Gobi 2k+ layout (1199:68a5 and 1199:68a9). The Sony driver also adds a non-standard QMI/net interface to the already supported 1199:9011 Gobi device. We do not know whether this is an alternate interface number or an additional interface which might be present, but that doesn't really matter. Lenovo provides a driver supporting 4 new devices: - MC7770 (1199:901b) with standard Gobi 2k+ layout - MC7700 (0f3d:68a2) with layout similar to MC7710 - MC7750 (114f:68a2) with layout similar to MC7710 - EM7700 (1199:901c) with layout similar to MC7710 Note regaring the three devices similar to MC7710: The Windows drivers only support interface #8 on these devices. The MC7710 can support QMI/net functions on interface #19 and #20 as well, and this driver is verified to work on interface #19 (a firmware bug is suspected to prevent #20 from working). We do not enable these additional interfaces until they either show up in a Windows driver or are verified to work in some other way. Therefore limiting the new devices to interface #8 for now.

This driver support many composite USB devices where the interface class/subclass/protocol provides no information about the interface function. Interfaces with different functions may all use ff/ff/ff, like this example of a device with three serial interfaces and three QMI/wwan interfaces: T: Bus=02 Lev=01 Prnt=01 Port=03 Cnt=01 Dev#=116 Spd=480 MxCh= 0 D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1 P: Vendor=1199 ProdID=68a2 Rev= 0.06 S: Manufacturer=Sierra Wireless, Incorporated S: Product=MC7710 S: SerialNumber=3581780xxxxxx C:* #Ifs= 6 Cfg#= 1 Atr=e0 MxPwr= 0mA I:* If#= 0 Alt= 0 #EPs= 2 Cls=ff(vend.)

The driver has had its own interface number whitelisting code to simulate this functionality. Replace this with generic interface number matching now that the USB subsystem support is there. This - removes the need for a driver_info structure per interface number, - avoids running the probe function for unsupported interfaces, and - simplifies the code. Signed-off-by:

Without this patch, I can't get netconsole logs remotely over vlan. The reason is probably we don't handle vlan tags in either netpoll tx or rx path.

This patch fixes several problems in the call path of netpoll_send_skb_on_dev(): 1. Disable IRQ's before calling netpoll_send_skb_on_dev(). 2. All the callees of netpoll_send_skb_on_dev() should use rcu_dereference_bh() to dereference ->npinfo. 3. Rename arp_reply() to netpoll_arp_reply(), the former is too generic. Cc: "David S.

In __netpoll_rx(), it dereferences ->npinfo without rcu_dereference_bh(), this patch fixes it by using the 'npinfo' passed from netpoll_rx() where it is already dereferenced with rcu_dereference_bh(). Cc: "David S. Miller" <davem@davemloft.net> Signed-off-by:

Like the previous patch, slave_disable_netpoll() and __netpoll_cleanup() may be called with read_lock() held too, so we should make them non-block, by moving the cleanup and kfree() to call_rcu_bh() callbacks. Cc: "David S. Miller" <davem@davemloft.net> Signed-off-by:

Commit 72121572 ("GPIO: gpio-pxa: fix devicetree functions") added an "xlate" function pointer to the irq_domain_ops, but this function is nor declared or defined anywhere when CONFIG_OF is disabled, causing the build error: drivers/gpio/gpio-pxa.c:532:11: error: 'irq_domain_xlate_twocell' undeclared here (not in a function) Extending the DT-only code section to cover the irq_domain_ops and the pxa_gpio_dt_ids solves this problem and makes it clearer which code is actually used without DT.

It seems we can not update the crtc scanout address. After disabling crtc, update to base address do not take effect after crtc being reenable leading to at least frame being scanout from the old crtc base address. Disabling crtc display request lead to same behavior. So after changing the vram address if we don't keep crtc disabled we will have the GPU trying to read some random system memory address with some iommu this will broke the crtc engine and will lead to broken display and iommu error message. So to avoid this, disable crtc. For flicker less boot we will need to avoid moving the vram start address.
