Remove the following redundant and never or rarely used kconfig syntax: - "def_boolean" (same as "def_bool") - "requires" (same as "depends on") - "depends" (same as "depends on") This patch contains the code changes and Kconfig updates. The shipped files are in next patch to let actual codechange stand out.

This can be useful if you are on a board which has a small amount

of memory or you wish to reserve some memory at the beginning of

the address space.

Note that you need to keep this value above 4k (0x1000) as this

memory region is used to capture NULL pointer references as well

Say Y here if you want to plug devices into your computer while

||
cases, the devices can likewise be unplugged at any time too.
|
||
|
||
One well known example of this is PCMCIA- or PC-cards, credit-card

size devices such as network cards, modems or hard drives which are
|
||
plugged into slots found on all modern laptop computers. Another
|
||
example, used on modern desktops as well as laptops, is USB.
|
||
|
||
Enable HOTPLUG and KMOD, and build a modular kernel. Get agent
|
||
software (at <http://linux-hotplug.sourceforge.net/>) and install it.
|
||
Then your kernel will automatically call out to a user mode "policy
|
||
agent" (/sbin/hotplug) to load modules and set up software needed
|
||
to use devices as you hotplug them.

Some pieces of the kernel contain a lot of flow changes which can
|
||
quickly fill up the hardware trace buffer. When debugging crashes,
|
||
the hardware trace may indicate that the problem lies in kernel
|
||
space when in reality an application is buggy.
|

|

Say Y here to disable hardware tracing in some known "jumpy" pieces
|
||
of code so that the trace buffer will extend further back.

This option enables special console drivers which allow the kernel
|
||
to print messages very early in the bootup process.
|
||
|
||
This is useful for kernel debugging when your machine crashes very
|
||
early before the console code is initialized. After enabling this
|
||
feature, you must add "earlyprintk=serial,uart0,57600" to the
|
||
command line (bootargs). It is safe to say Y here in all cases, as
|
||
all of this lives in the init section and is thrown away after the
|
||
kernel boots completely.

Usually the pointer transfer from user space is checked to see if its
