+Description:
+		This directory exposes interfaces for interactive with
+		EFI variables.  For more information on EFI variables,
+		see 'Variable Services' in the UEFI specification
+		(section 7.2 in specification version 2.3 Errata D).
+
+		In summary, EFI variables are named, and are classified
+		into separate namespaces through the use of a vendor
+		GUID.  They also have an arbitrary binary value
+		associated with them.
+
+		The efivars module enumerates these variables and
+		creates a separate directory for each one found.  Each
+		directory has a name of the form "<key>-<vendor guid>"
+		and contains the following files:
+
+		attributes:	A read-only text file enumerating the
+				EFI variable flags.  Potential values
+				include:
+
+				EFI_VARIABLE_NON_VOLATILE
+				EFI_VARIABLE_BOOTSERVICE_ACCESS
+				EFI_VARIABLE_RUNTIME_ACCESS
+				EFI_VARIABLE_HARDWARE_ERROR_RECORD
+				EFI_VARIABLE_AUTHENTICATED_WRITE_ACCESS
+
+				See the EFI documentation for an
+				explanation of each of these variables.
+
+		data:		A read-only binary file that can be read
+				to attain the value of the EFI variable
+
+		guid:		The vendor GUID of the variable.  This
+				should always match the GUID in the
+				variable's name.
+
+		raw_var:	A binary file that can be read to obtain
+				a structure that contains everything
+				there is to know about the variable.
+				For structure definition see "struct
+				efi_variable" in the kernel sources.
+
+				This file can also be written to in
+				order to update the value of a variable.
+				For this to work however, all fields of
+				the "struct efi_variable" passed must
+				match byte for byte with the structure
+				read out of the file, save for the value
+				portion.
+
+				**Note** the efi_variable structure
+				read/written with this file contains a
+				'long' type that may change widths
+				depending on your underlying
+				architecture.
+
+		size:		As ASCII representation of the size of
+				the variable's value.
+
+
+		In addition, two other magic binary files are provided
+		in the top-level directory and are used for adding and
+		removing variables:
+
+		new_var:	Takes a "struct efi_variable" and
+				instructs the EFI firmware to create a
+				new variable.
+
+		del_var:	Takes a "struct efi_variable" and
+				instructs the EFI firmware to remove any
+				variable that has a matching vendor GUID
+				and variable key name.

+Description:
+		Many machines' firmware (x86 and ia64) export DMI /
+		SMBIOS tables to the operating system.  Getting at this
+		information is often valuable to userland, especially in
+		cases where there are OEM extensions used.
+
+		The kernel itself does not rely on the majority of the
+		information in these tables being correct.  It equally
+		cannot ensure that the data as exported to userland is
+		without error either.
+
+		DMI is structured as a large table of entries, where
+		each entry has a common header indicating the type and
+		length of the entry, as well as 'handle' that is
+		supposed to be unique amongst all entries.
+
+		Some entries are required by the specification, but many
+		others are optional.  In general though, users should
+		never expect to find a specific entry type on their
+		system unless they know for certain what their firmware
+		is doing.  Machine to machine will vary.
+
+		Multiple entries of the same type are allowed.  In order
+		to handle these duplicate entry types, each entry is
+		assigned by the operating system an 'instance', which is
+		derived from an entry type's ordinal position.  That is
+		to say, if there are 'N' multiple entries with the same type
+		'T' in the DMI tables (adjacent or spread apart, it
+		doesn't matter), they will be represented in sysfs as
+		entries "T-0" through "T-(N-1)":
+
+		Example entry directories:
+
+			/sys/firmware/dmi/entries/17-0
+			/sys/firmware/dmi/entries/17-1
+			/sys/firmware/dmi/entries/17-2
+			/sys/firmware/dmi/entries/17-3
+			...
+
+		Instance numbers are used in lieu of the firmware
+		assigned entry handles as the kernel itself makes no
+		guarantees that handles as exported are unique, and
+		there are likely firmware images that get this wrong in
+		the wild.
+
+		Each DMI entry in sysfs has the common header values
+		exported as attributes:
+
+		handle	: The 16bit 'handle' that is assigned to this
+			  entry by the firmware.  This handle may be
+			  referred to by other entries.
+		length	: The length of the entry, as presented in the
+			  entry itself.  Note that this is _not the
+			  total count of bytes associated with the
+			  entry_.  This value represents the length of
+			  the "formatted" portion of the entry.  This
+			  "formatted" region is sometimes followed by
+			  the "unformatted" region composed of nul
+			  terminated strings, with termination signalled
+			  by a two nul characters in series.
+		raw	: The raw bytes of the entry. This includes the
+			  "formatted" portion of the entry, the
+			  "unformatted" strings portion of the entry,
+			  and the two terminating nul characters.
+		type	: The type of the entry.  This value is the same
+			  as found in the directory name.  It indicates
+			  how the rest of the entry should be
+			  interpreted.
+		instance: The instance ordinal of the entry for the
+			  given type.  This value is the same as found
+			  in the parent directory name.
+		position: The position of the entry within the entirety
+			  of the entirety.
+
+		=== Entry Specialization ===
+
+		Some entry types may have other information available in
+		sysfs.
+
+		--- Type 15 - System Event Log ---
+
+		This entry allows the firmware to export a log of
+		events the system has taken.  This information is
+		typically backed by nvram, but the implementation
+		details are abstracted by this table.  This entries data
+		is exported in the directory:
+
+		/sys/firmware/dmi/entries/15-0/system_event_log
+
+		and has the following attributes (documented in the
+		SMBIOS / DMI specification under "System Event Log (Type 15)":
+
+		area_length
+		header_start_offset
+		data_start_offset
+		access_method
+		status
+		change_token
+		access_method_address
+		header_format
+		per_log_type_descriptor_length
+		type_descriptors_supported_count
+
+		As well, the kernel exports the binary attribute:
+
+		raw_event_log	: The raw binary bits of the event log
+				  as described by the DMI entry.

+Description:

+Date:		January 2010

+Contact:	"Pavan Savoy" <pavan_savoy@ti.com>
+Description:
+		When one of the protocols Bluetooth, FM or GPS wants to make
+		use of the shared UART transport, it registers to the shared
+		transport driver, which will signal the user-space for opening,
+		configuring baud and install line discipline via this sysfs
+		entry. This entry would be polled upon by the user-space
+		daemon managing the UART, and is notified about the change
+		by the sysfs_notify. The value would be '1' when UART needs
+		to be opened/ldisc installed, and would be '0' when UART
+		is no more required and needs to be closed.

+Linux内核开发者认为安全非常重要。因此，我们想要知道当一个有关于
+安全的漏洞被发现的时候，并且它可能会被尽快的修复或者公开。请把这个安全
+漏洞报告给Linux内核安全团队。
+
+1) 联系
+
+linux内核安全团队可以通过email<security@kernel.org>来联系。这是
+一组独立的安全工作人员，可以帮助改善漏洞报告并且公布和取消一个修复。安
+全团队有可能会从部分的维护者那里引进额外的帮助来了解并且修复安全漏洞。
+当遇到任何漏洞，所能提供的信息越多就越能诊断和修复。如果你不清楚什么
+是有帮助的信息，那就请重温一下REPORTING-BUGS文件中的概述过程。任
+何攻击性的代码都是非常有用的，未经报告者的同意不会被取消，除非它已经
+被公布于众。
+
+2) 公开
+
+Linux内核安全团队的宗旨就是和漏洞提交者一起处理漏洞的解决方案直
+到公开。我们喜欢尽快地完全公开漏洞。当一个漏洞或者修复还没有被完全地理
+解，解决方案没有通过测试或者供应商协调，可以合理地延迟公开。然而，我们
+期望这些延迟尽可能的短些，是可数的几天，而不是几个星期或者几个月。公开
+日期是通过安全团队和漏洞提供者以及供应商洽谈后的结果。公开时间表是从很
+短（特殊的，它已经被公众所知道）到几个星期。作为一个基本的默认政策，我
+们所期望通知公众的日期是7天的安排。
+
+3) 保密协议
+
+Linux内核安全团队不是一个正式的团体，因此不能加入任何的保密协议。

+以下为正文
+---------------------------------------------------------------------
+这个文件是有关当前使用的魔术值注册表。当你给一个结构添加了一个魔术值，你也应该把这个魔术值添加到这个文件，因为我们最好把用于各种结构的魔术值统一起来。
+
+使用魔术值来保护内核数据结构是一个非常好的主意。这就允许你在运行期检查(a)一个结构是否已经被攻击，或者(b)你已经给一个例行程序通过了一个错误的结构。后一种情况特别地有用---特别是当你通过一个空指针指向结构体的时候。tty源码，例如，经常通过特定驱动使用这种方法并且反复地排列特定方面的结构。
+
+使用魔术值的方法是在结构的开始处声明的，如下：
+
+struct tty_ldisc {
+	int	magic;
+	...
+};
+
+当你以后给内核添加增强功能的时候，请遵守这条规则！这样就会节省数不清的调试时间，特别是一些古怪的情况，例如，数组超出范围并且重新写了超出部分。遵守这个规则，‪这些情况可以被快速地，安全地避免。
