[PATCH v2 64/79] docs: ioctl-number.txt: convert it to ReST format

[Mauro Carvalho Chehab <mchehab+samsung@kernel.org>]

The conversion itself is simple: add a markup for the
title of this file and add markups for both tables.

Yet, the big table here with IOCTL numbers is badly formatted:
on several lines, the "Include File" column has some values that
are bigger than the reserved space there.

Also, on several places, a comment was misplaced at the "Include
File" space.

So, most of the work here is to actually ensure that each field
will be properly fixed.

Also worth to mention that some URLs have the asterisk character
on it. Well, Sphinx has an issue with asterisks in the middle
of an string. As this is URL, use the alternate format: %2A.

As a side effect of this patch, it is now a lot easier to see that
some reserved ioctl numbers are missing the include files
where it is supposed to be used.

PS.: While this is part of a subdir, I opted to convert this
single file alone, as this file has a potential of conflicts,
as most subsystem maintainers touch it.

+Ioctl Numbers
+=============
+
+19 October 1999

+Michael Elizabeth Chastain
+<mec@shout.net>
+
+If you are adding new ioctl's to the kernel, you should use the _IO
+macros defined in <linux/ioctl.h>:
+
+    ====== == ============================================
+    _IO    an ioctl with no parameters
+    _IOW   an ioctl with write parameters (copy_from_user)
+    _IOR   an ioctl with read parameters  (copy_to_user)
+    _IOWR  an ioctl with both write and read parameters.
+    ====== == ============================================
+
+'Write' and 'read' are from the user's point of view, just like the
+system calls 'write' and 'read'.  For example, a SET_FOO ioctl would
+be _IOW, although the kernel would actually read data from user space;
+a GET_FOO ioctl would be _IOR, although the kernel would actually write
+data to user space.
+
+The first argument to _IO, _IOW, _IOR, or _IOWR is an identifying letter
+or number from the table below.  Because of the large number of drivers,
+many drivers share a partial letter with other drivers.
+
+If you are writing a driver for a new device and need a letter, pick an
+unused block with enough room for expansion: 32 to 256 ioctl commands.
+You can register the block by patching this file and submitting the
+patch to Linus Torvalds.  Or you can e-mail me at <mec@shout.net> and
+I'll register one for you.
+
+The second argument to _IO, _IOW, _IOR, or _IOWR is a sequence number
+to distinguish ioctls from each other.  The third argument to _IOW,
+_IOR, or _IOWR is the type of the data going into the kernel or coming
+out of the kernel (e.g.  'int' or 'struct foo').  NOTE!  Do NOT use
+sizeof(arg) as the third argument as this results in your ioctl thinking
+it passes an argument of type size_t.
+
+Some devices use their major number as the identifier; this is OK, as
+long as it is unique.  Some devices are irregular and don't follow any
+convention at all.
+
+Following this convention is good because:
+
+(1) Keeping the ioctl's globally unique helps error checking:
+    if a program calls an ioctl on the wrong device, it will get an
+    error rather than some unexpected behaviour.
+
+(2) The 'strace' build procedure automatically finds ioctl numbers
+    defined with _IO, _IOW, _IOR, or _IOWR.
+
+(3) 'strace' can decode numbers back into useful names when the
+    numbers are unique.
+
+(4) People looking for ioctls can grep for them more easily when
+    this convention is used to define the ioctl numbers.
+
+(5) When following the convention, the driver code can use generic
+    code to copy the parameters between user and kernel space.
+
+This table lists ioctls visible from user land for Linux/x86.  It contains
+most drivers up to 2.6.31, but I know I am missing some.  There has been
+no attempt to list non-X86 architectures or ioctls from drivers/staging/.

-Ioctl Numbers
-19 October 1999
-Michael Elizabeth Chastain
-<mec@shout.net>
-
-If you are adding new ioctl's to the kernel, you should use the _IO
-macros defined in <linux/ioctl.h>:
-
-    _IO    an ioctl with no parameters
-    _IOW   an ioctl with write parameters (copy_from_user)
-    _IOR   an ioctl with read parameters  (copy_to_user)
-    _IOWR  an ioctl with both write and read parameters.
-
-'Write' and 'read' are from the user's point of view, just like the
-system calls 'write' and 'read'.  For example, a SET_FOO ioctl would
-be _IOW, although the kernel would actually read data from user space;
-a GET_FOO ioctl would be _IOR, although the kernel would actually write
-data to user space.
-
-The first argument to _IO, _IOW, _IOR, or _IOWR is an identifying letter
-or number from the table below.  Because of the large number of drivers,
-many drivers share a partial letter with other drivers.
-
-If you are writing a driver for a new device and need a letter, pick an
-unused block with enough room for expansion: 32 to 256 ioctl commands.
-You can register the block by patching this file and submitting the
-patch to Linus Torvalds.  Or you can e-mail me at <mec@shout.net> and
-I'll register one for you.
-
-The second argument to _IO, _IOW, _IOR, or _IOWR is a sequence number
-to distinguish ioctls from each other.  The third argument to _IOW,
-_IOR, or _IOWR is the type of the data going into the kernel or coming
-out of the kernel (e.g.  'int' or 'struct foo').  NOTE!  Do NOT use
-sizeof(arg) as the third argument as this results in your ioctl thinking
-it passes an argument of type size_t.
-
-Some devices use their major number as the identifier; this is OK, as
-long as it is unique.  Some devices are irregular and don't follow any
-convention at all.
-
-Following this convention is good because:
-
-(1) Keeping the ioctl's globally unique helps error checking:
-    if a program calls an ioctl on the wrong device, it will get an
-    error rather than some unexpected behaviour.
-
-(2) The 'strace' build procedure automatically finds ioctl numbers
-    defined with _IO, _IOW, _IOR, or _IOWR.
-
-(3) 'strace' can decode numbers back into useful names when the
-    numbers are unique.
-
-(4) People looking for ioctls can grep for them more easily when
-    this convention is used to define the ioctl numbers.
-
-(5) When following the convention, the driver code can use generic
-    code to copy the parameters between user and kernel space.
-
-This table lists ioctls visible from user land for Linux/x86.  It contains
-most drivers up to 2.6.31, but I know I am missing some.  There has been
-no attempt to list non-X86 architectures or ioctls from drivers/staging/.
