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

 312           the address space.
 313
 314           Note that you generally want to keep this value at or above 4k
 315           (0x1000) as this will allow the kernel to capture NULL pointer
 316           references.

 941           from 0x0000 - 0x0FFF (the first 4k) of memory.  This is useful in
 942           catching common programming errors such as NULL pointer dereferences.
 943
 944           Misbehaving applications will be killed (generate a SEGV) while the
 945           kernel will trigger a panic.
 946
 947           Enabling this option will take up an extra entry in CPLB table.
 948           Otherwise, there is no extra overhead.

 954           Some pieces of the kernel contain a lot of flow changes which can
 955           quickly fill up the hardware trace buffer.  When debugging crashes,
 956           the hardware trace may indicate that the problem lies in kernel
 957           space when in reality an application is buggy.
 958
 959           Say Y here to disable hardware tracing in some known "jumpy" pieces
 960           of code so that the trace buffer will extend further back.

 978           Usually the pointer transfer from user space is checked to see if its
 979           address is in the kernel space.
 980
 981           Say N here to disable that check to improve the performance.
