- Simplifying the Kconfig use of FTRACE and TRACE_IRQFLAGS_SUPPORT
- bootconfig now can start histograms
- bootconfig supports group/all enabling
- histograms now can put values in linear size buckets
- execnames can be passed to synthetic events
- Introduction of "event probes" that attach to other events and
can retrieve data from pointers of fields, or record fields
as different types (a pointer to a string as a string instead
of just a hex number)
- Various fixes and clean ups

On some platforms, there is currently no way for the boot loader
|
|
to pass arguments to the kernel. For these, you should supply some
|
|
command-line options at build time by entering them here. At a
|
|
minimum, you should specify the memory size and the root device
|
|
(e.g., mem=64M root=/dev/nfs).

This allows you to specify the maximum number of CPUs which this
|
|
kernel will support. The maximum supported value is 6 and the
|
|
minimum value which makes sense is 2.
|
|
|
|
This is purely to save memory - each supported CPU adds
|
|
approximately eight kilobytes to the kernel image.
