Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

13 bool "Unix98 PTY support"
14 ---help---
15 A pseudo terminal (PTY) is a software device consisting of two
16 halves: a master and a slave. The slave device behaves identical to
17 a physical terminal; the master device is used by a process to
18 read data from and write data to the slave, thereby emulating a
19 terminal. Typical programs for the master side are telnet servers
20 and xterms.
21
22 Linux has traditionally used the BSD-like names /dev/ptyxx for
23 masters and /dev/ttyxx for slaves of pseudo terminals. This scheme
24 has a number of problems. The GNU C library glibc 2.1 and later,
25 however, supports the Unix98 naming standard: in order to acquire a
26 pseudo terminal, a process opens /dev/ptmx; the number of the pseudo
27 terminal is then made available to the process and the pseudo
28 terminal slave can be accessed as /dev/pts/<number>. What was
29 traditionally /dev/ttyp2 will then be /dev/pts/2, for example.
30
31 The entries in /dev/pts/ are created on the fly by a virtual
32 file system; therefore, if you say Y here you should say Y to
33 "/dev/pts file system for Unix98 PTYs" as well.
34
35 If you want to say Y here, you need to have the C library glibc 2.1
36 or later (equal to libc-6.1, check with "ls -l /lib/libc.so.*").
37 Read the instructions in <file:Documentation/Changes> pertaining to
38 pseudo terminals. It's safe to say N.

43 default "256"
44 help
45 The maximum number of Unix98 PTYs that can be used at any one time.
46 The default is 256, and should be enough for desktop systems. Server
47 machines which support incoming telnet/rlogin/ssh connections and/or
48 serve several X terminals may want to increase this: every incoming
49 connection and every xterm uses up one PTY.
50
51 When not in use, each additional set of 256 PTYs occupy
52 approximately 8 KB of kernel memory on 32-bit architectures.

134 This option enables the hardware console interface for system
135 identification. This is commonly used for workload management and
136 gives you a nice name for the system on the service element.
137 Please select this option as a module since built-in operation is
138 completely untested.
139 You should only select this option if you know what you are doing,
140 need this feature and intend to run your kernel in LPAR.
