Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/klassert/ipsec-next
Steffen Klassert says:
====================
1) Introduce skb_to_sgvec_nomark function to add further data to the sg list
without calling sg_unmark_end first. Needed to add extended sequence
number informations. From Fan Du.
2) Add IPsec extended sequence numbers support to the Authentication Header
protocol for ipv4 and ipv6. From Fan Du.
3) Make the IPsec flowcache namespace aware, from Fan Du.
4) Avoid creating temporary SA for every packet when no key manager is
registered. From Horia Geanta.
5) Support filtering of SA dumps to show only the SAs that match a
given filter. From Nicolas Dichtel.
6) Remove caching of xfrm_policy_sk_bundles. The cached socket policy bundles
are never used, instead we create a new cache entry whenever xfrm_lookup()
is called on a socket policy. Most protocols cache the used routes to the
socket, so this caching is not needed.
7) Fix a forgotten SADB_X_EXT_FILTER length check in pfkey, from Nicolas
Dichtel.
8) Cleanup error handling of xfrm_state_clone.
====================

+STMicroelectronics SoC DWMAC glue layer controller
+
+The device node has following properties.
+
+Required properties:
+ - compatible : Can be "st,stih415-dwmac", "st,stih416-dwmac" or
+ "st,stid127-dwmac".
+ - reg : Offset of the glue configuration register map in system
+ configuration regmap pointed by st,syscon property and size.
+
+ - reg-names : Should be "sti-ethconf".
+
+ - st,syscon : Should be phandle to system configuration node which
+ encompases this glue registers.
+
+ - st,tx-retime-src: On STi Parts for Giga bit speeds, 125Mhz clocks can be
+ wired up in from different sources. One via TXCLK pin and other via CLK_125
+ pin. This wiring is totally board dependent. However the retiming glue
+ logic should be configured accordingly. Possible values for this property
+
+ "txclk" - if 125Mhz clock is wired up via txclk line.
+ "clk_125" - if 125Mhz clock is wired up via clk_125 line.
+
+ This property is only valid for Giga bit setup( GMII, RGMII), and it is
+ un-used for non-giga bit (MII and RMII) setups. Also note that internal
+ clockgen can not generate stable 125Mhz clock.
+
+ - st,ext-phyclk: This boolean property indicates who is generating the clock
+ for tx and rx. This property is only valid for RMII case where the clock can
+ be generated from the MAC or PHY.
+
+ - clock-names: should be "sti-ethclk".
+ - clocks: Should point to ethernet clockgen which can generate phyclk.

-The 3Com Etherlink Plus (3c505) driver.
-
-This driver now uses DMA. There is currently no support for PIO operation.
-The default DMA channel is 6; this is _not_ autoprobed, so you must
-make sure you configure it correctly. If loading the driver as a
-module, you can do this with "modprobe 3c505 dma=n". If the driver is
-linked statically into the kernel, you must either use an "ether="
-statement on the command line, or change the definition of ELP_DMA in 3c505.h.
-
-The driver will warn you if it has to fall back on the compiled in
-default DMA channel.
-
-If no base address is given at boot time, the driver will autoprobe
-ports 0x300, 0x280 and 0x310 (in that order). If no IRQ is given, the driver
-will try to probe for it.
-
-The driver can be used as a loadable module.
-
-Theoretically, one instance of the driver can now run multiple cards,
-in the standard way (when loading a module, say "modprobe 3c505
-io=0x300,0x340 irq=10,11 dma=6,7" or whatever). I have not tested
-this, though.
-
-The driver may now support revision 2 hardware; the dependency on
-being able to read the host control register has been removed. This
-is also untested, since I don't have a suitable card.
-
-Known problems:
- I still see "DMA upload timed out" messages from time to time. These
-seem to be fairly non-fatal though.
- The card is old and slow.
-
-To do:
- Improve probe/setup code
- Test multicast and promiscuous operation
-
-Authors:
- The driver is mainly written by Craig Southeren, email
- <craigs@ineluki.apana.org.au>.

- IRQ/address detection, some changes) and this README by

The Gianfar Ethernet Driver
-Sysfs File description
Author: Andy Fleming <afleming@freescale.com>
Updated: 2005-07-28
-SYSFS
-
-Several of the features of the gianfar driver are controlled
-through sysfs files. These are:
-
-bd_stash:
-To stash RX Buffer Descriptors in the L2, echo 'on' or '1' to
-bd_stash, echo 'off' or '0' to disable
-
-rx_stash_len:
-To stash the first n bytes of the packet in L2, echo the number
-of bytes to buf_stash_len. echo 0 to disable.
-
-WARNING: You could really screw these up if you set them too low or high!
-fifo_threshold:
-To change the number of bytes the controller needs in the
-fifo before it starts transmission, echo the number of bytes to
-fifo_thresh. Range should be 0-511.
-
-fifo_starve:
-When the FIFO has less than this many bytes during a transmit, it
-enters starve mode, and increases the priority of TX memory
-transactions. To change, echo the number of bytes to
-fifo_starve. Range should be 0-511.
-
-fifo_starve_off:
-Once in starve mode, the FIFO remains there until it has this
-many bytes. To change, echo the number of bytes to
-fifo_starve_off. Range should be 0-511.

+ Linux 在 AArch64 中带标记的虚拟地址
+ =================================
+
+作者: Will Deacon <will.deacon@arm.com>
+日期: 2013 年 06 月 12 日
+
+本文档简述了在 AArch64 地址转换系统中提供的带标记的虚拟地址及其在
+AArch64 Linux 中的潜在用途。
+
+内核提供的地址转换表配置使通过 TTBR0 完成的虚拟地址转换（即用户空间
+映射），其虚拟地址的最高 8 位（63:56）会被转换硬件所忽略。这种机制
+让这些位可供应用程序自由使用，其注意事项如下：
+
+ (1) 内核要求所有传递到 EL1 的用户空间地址带有 0x00 标记。
+ 这意味着任何携带用户空间虚拟地址的系统调用（syscall）
+ 参数 *必须* 在陷入内核前使它们的最高字节被清零。
+
+ (2) 非零标记在传递信号时不被保存。这意味着在应用程序中利用了
+ 标记的信号处理函数无法依赖 siginfo_t 的用户空间虚拟
+ 地址所携带的包含其内部域信息的标记。此规则的一个例外是
+ 当信号是在调试观察点的异常处理程序中产生的，此时标记的
+ 信息将被保存。
+
+ (3) 当使用带标记的指针时需特别留心，因为仅对两个虚拟地址
+ 的高字节，C 编译器很可能无法判断它们是不同的。
+
+此构架会阻止对带标记的 PC 指针的利用，因此在异常返回时，其高字节
+将被设置成一个为 “55” 的扩展符。
