Merge commit '517ffce4e1a03aea979fe3a18a3dd1761a24fafb' into arch-sparc

Backmerge from the point in mainline where a trivial conflict had been
introduced (arch/sparc/kernel/sys_sparc_64.c had grown sys_kern_features()
right after where kernel_execve() used to be)

-The SMBus Driver
-----------------
-
-The SMBus driver allows up to 4 SMBus devices to be configured in the
-system.  By default, the driver will register any SMBus interfaces it finds
-in the I2C address range of 0x20 to 0x4f on any adapter.  You can change this
-at module load time (for a module) with:
-
-  modprobe ipmi_smb.o
-	addr=<adapter1>,<i2caddr1>[,<adapter2>,<i2caddr2>[,...]]
-	dbg=<flags1>,<flags2>...
-	[defaultprobe=1] [dbg_probe=1]
-
-The addresses are specified in pairs, the first is the adapter ID and the
-second is the I2C address on that adapter.
-
-The debug flags are bit flags for each BMC found, they are:
-IPMI messages: 1, driver state: 2, timing: 4, I2C probe: 8
-
-Setting smb_defaultprobe to zero disabled the default probing of SMBus
-interfaces at address range 0x20 to 0x4f.  This means that only the
-BMCs specified on the smb_addr line will be detected.
-
-Setting smb_dbg_probe to 1 will enable debugging of the probing and
-detection process for BMCs on the SMBusses.
-
-Discovering the IPMI compliant BMC on the SMBus can cause devices
-on the I2C bus to fail. The SMBus driver writes a "Get Device ID" IPMI
-message as a block write to the I2C bus and waits for a response.
-This action can be detrimental to some I2C devices. It is highly recommended
-that the known I2c address be given to the SMBus driver in the smb_addr
-parameter. The default address range will not be used when a smb_addr
-parameter is provided.
-
-When compiled into the kernel, the addresses can be specified on the
-kernel command line as:
-
-  ipmb_smb.addr=<adapter1>,<i2caddr1>[,<adapter2>,<i2caddr2>[,...]]
-	ipmi_smb.dbg=<flags1>,<flags2>...
-	ipmi_smb.defaultprobe=0 ipmi_smb.dbg_probe=1
-
-These are the same options as on the module command line.
-
-Note that you might need some I2C changes if CONFIG_IPMI_PANIC_EVENT
-is enabled along with this, so the I2C driver knows to run to
-completion during sending a panic event.

+何为 IRQ?
+
+一个 IRQ 是来自某个设备的一个中断请求。目前，它们可以来自一个硬件引脚，
+或来自一个数据包。多个设备可能连接到同个硬件引脚，从而共享一个 IRQ。
+
+一个 IRQ 编号是用于告知硬件中断源的内核标识。通常情况下，这是一个
+全局 irq_desc 数组的索引，但是除了在 linux/interrupt.h 中的实现，
+具体的细节是体系结构特定的。
+
+一个 IRQ 编号是设备上某个可能的中断源的枚举。通常情况下，枚举的编号是
+该引脚在系统内中断控制器的所有输入引脚中的编号。对于 ISA 总线中的情况，
+枚举的是在两个 i8259 中断控制器中 16 个输入引脚。
+
+架构可以对 IRQ 编号指定额外的含义，在硬件涉及任何手工配置的情况下，
+是被提倡的。ISA 的 IRQ 是一个分配这类额外含义的典型例子。

+			启动 AArch64 Linux
+			==================
+
+作者: Will Deacon <will.deacon@arm.com>
+日期: 2012 年 09 月 07 日
+
+本文档基于 Russell King 的 ARM 启动文档，且适用于所有公开发布的
+AArch64 Linux 内核代码。
+
+AArch64 异常模型由多个异常级别（EL0 - EL3）组成，对于 EL0 和 EL1
+异常级有对应的安全和非安全模式。EL2 是系统管理级，且仅存在于
+非安全模式下。EL3 是最高特权级，且仅存在于安全模式下。
+
+基于本文档的目的，我们将简单地使用‘引导装载程序’（‘boot loader’）
+这个术语来定义在将控制权交给 Linux 内核前 CPU 上执行的所有软件。
+这可能包含安全监控和系统管理代码，或者它可能只是一些用于准备最小启动
+环境的指令。
+
+基本上，引导装载程序（至少）应实现以下操作：
+
+1、设置和初始化 RAM
+2、设置设备树数据
+3、解压内核映像
+4、调用内核映像
+
+
+1、设置和初始化 RAM
+-----------------
+
+必要性: 强制
+
+引导装载程序应该找到并初始化系统中所有内核用于保持系统变量数据的 RAM。
+这个操作的执行是设备依赖的。（它可能使用内部算法来自动定位和计算所有
+RAM，或可能使用对这个设备已知的 RAM 信息，还可能使用任何引导装载程序
+设计者想到的匹配方法。）
+
+
+2、设置设备树数据
+---------------
+
+必要性: 强制
+
+设备树数据块（dtb）大小必须不大于 2 MB，且位于从内核映像起始算起第一个
+512MB 内的 2MB 边界上。这使得内核可以通过初始页表中的单个节描述符来
+映射此数据块。
+
+
+3、解压内核映像
+-------------
+
+必要性: 可选
+
+AArch64 内核当前没有提供自解压代码，因此如果使用了压缩内核映像文件
+（比如 Image.gz），则需要通过引导装载程序（使用 gzip 等）来进行解压。
+若引导装载程序没有实现这个需求，就要使用非压缩内核映像文件。
+
+
+4、调用内核映像
+-------------
+
+必要性: 强制
+
+已解压的内核映像包含一个 32 字节的头，内容如下：
+
+  u32 magic	= 0x14000008;	/* 跳转到 stext, 小端 */
+  u32 res0	= 0;		/* 保留 */
+  u64 text_offset;		/* 映像装载偏移 */
+  u64 res1	= 0;		/* 保留 */
+  u64 res2	= 0;		/* 保留 */
+
+映像必须位于系统 RAM 起始处的特定偏移（当前是 0x80000）。系统 RAM
+的起始地址必须是以 2MB 对齐的。
+
+在跳转入内核前，必须符合以下状态：
+
+- 停止所有 DMA 设备，这样内存数据就不会因为虚假网络包或磁盘数据而
+  被破坏。这可能可以节省你许多的调试时间。
+
+- 主 CPU 通用寄存器设置
+  x0 = 系统 RAM 中设备树数据块（dtb）的物理地址。
+  x1 = 0 (保留，将来可能使用)
+  x2 = 0 (保留，将来可能使用)
+  x3 = 0 (保留，将来可能使用)
+
+- CPU 模式
+  所有形式的中断必须在 PSTATE.DAIF 中被屏蔽（Debug、SError、IRQ
+  和 FIQ）。
+  CPU 必须处于 EL2（推荐，可访问虚拟化扩展）或非安全 EL1 模式下。
+
+- 高速缓存、MMU
+  MMU 必须关闭。
+  指令缓存开启或关闭都可以。
+  数据缓存必须关闭且无效。
+  外部高速缓存（如果存在）必须配置并禁用。
+
+- 架构计时器
+  CNTFRQ 必须设定为计时器的频率。
+  如果在 EL1 模式下进入内核，则 CNTHCTL_EL2 中的 EL1PCTEN (bit 0)
+  必须置位。
+
+- 一致性
+  通过内核启动的所有 CPU 在内核入口地址上必须处于相同的一致性域中。
+  这可能要根据具体实现来定义初始化过程，以使能每个CPU上对维护操作的
+  接收。
+
+- 系统寄存器
+  在进入内核映像的异常级中，所有构架中可写的系统寄存器必须通过软件
+  在一个更高的异常级别下初始化，以防止在 未知 状态下运行。
+
+引导装载程序必须在每个 CPU 处于以下状态时跳入内核入口：
+
+- 主 CPU 必须直接跳入内核映像的第一条指令。通过此 CPU 传递的设备树
+  数据块必须在每个 CPU 节点中包含以下内容：
+
+    1、‘enable-method’属性。目前，此字段支持的值仅为字符串“spin-table”。
+
+    2、‘cpu-release-addr’标识一个 64-bit、初始化为零的内存位置。
+
+  引导装载程序必须生成这些设备树属性，并在跳入内核入口之前将其插入
+  数据块。
+
+- 任何辅助 CPU 必须在内存保留区（通过设备树中的 /memreserve/ 域传递
+  给内核）中自旋于内核之外，轮询它们的 cpu-release-addr 位置（必须
+  包含在保留区中）。可通过插入 wfe 指令来降低忙循环开销，而主 CPU 将
+  发出 sev 指令。当对 cpu-release-addr 所指位置的读取操作返回非零值
+  时，CPU 必须直接跳入此值所指向的地址。
+
+- 辅助 CPU 通用寄存器设置
+  x0 = 0 (保留，将来可能使用)
+  x1 = 0 (保留，将来可能使用)
+  x2 = 0 (保留，将来可能使用)
+  x3 = 0 (保留，将来可能使用)

+		     Linux 在 AArch64 中的内存布局
+		     ===========================
+
+作者: Catalin Marinas <catalin.marinas@arm.com>
+日期: 2012 年 02 月 20 日
+
+本文档描述 AArch64 Linux 内核所使用的虚拟内存布局。此构架可以实现
+页大小为 4KB 的 4 级转换表和页大小为 64KB 的 3 级转换表。
+
+AArch64 Linux 使用页大小为 4KB 的 3 级转换表配置，对于用户和内核
+都有 39-bit (512GB) 的虚拟地址空间。对于页大小为 64KB的配置，仅
+使用 2 级转换表，但内存布局相同。
+
+用户地址空间的 63:39 位为 0，而内核地址空间的相应位为 1。TTBRx 的
+选择由虚拟地址的 63 位给出。swapper_pg_dir 仅包含内核（全局）映射，
+而用户 pgd 仅包含用户（非全局）映射。swapper_pgd_dir 地址被写入
+TTBR1 中，且从不写入 TTBR0。
+
+

+** Created 09/29/92 by Greg Harp
+**
+** 5/2/94 Roman Hodek:
+**   Added bi_atari part of the machine dependent union bi_un; for now it
+**   contains just a model field to distinguish between TT and Falcon.
+** 26/7/96 Roman Zippel:
+**   Renamed to setup.h; added some useful macros to allow gcc some
+**   optimizations if possible.
+** 5/10/96 Geert Uytterhoeven:
+**   Redesign of the boot information structure; moved boot information
+**   structure to bootinfo.h

- * Linux system call numbers.

- * Cary Coutant says that we should just use another syscall gateway
- * page to avoid clashing with the HPUX space, and I think he's right:
- * it will would keep a branch out of our syscall entry path, at the
- * very least.  If we decide to change it later, we can ``just'' tweak
- * the LINUX_GATEWAY_ADDR define at the bottom and make __NR_Linux be
- * 1024 or something.  Oh, and recompile libc. =)
- *
- * 64-bit HPUX binaries get the syscall gateway address passed in a register
- * from the kernel at startup, which seems a sane strategy.

+ * This file holds USB constants and structures that are needed for
+ * USB device APIs.  These are used by the USB device model, which is
+ * defined in chapter 9 of the USB 2.0 specification and in the
+ * Wireless USB 1.0 (spread around).  Linux has several APIs in C that
+ * need these:
+ *
+ * - the master/host side Linux-USB kernel driver API;
+ * - the "usbfs" user space API; and
+ * - the Linux "gadget" slave/device/peripheral side driver API.
+ *
+ * USB 2.0 adds an additional "On The Go" (OTG) mode, which lets systems
+ * act either as a USB master/host or as a USB slave/device.  That means
+ * the master and slave side APIs benefit from working well together.
+ *
+ * There's also "Wireless USB", using low power short range radios for
+ * peripheral interconnection but otherwise building on the USB framework.
+ *
+ * Note all descriptors are declared '__attribute__((packed))' so that:
+ *
+ * [a] they never get padded, either internally (USB spec writers
+ *     probably handled that) or externally;
+ *
+ * [b] so that accessing bigger-than-a-bytes fields will never
+ *     generate bus errors on any platform, even when the location of
+ *     its descriptor inside a bundle isn't "naturally aligned", and
+ *
+ * [c] for consistency, removing all doubt even when it appears to
+ *     someone that the two other points are non-issues for that
+ *     particular descriptor type.
