[PATCH] frv: drop unsupported debugging features
Drop support for debugging features that aren't supported on FRV: (*) EARLY_PRINTK The on-chip UARTs are set up early enough that this isn't required, and VGA support isn't available. There's also a gdbstub available. (*) DEBUG_PAGEALLOC This can't be easily be done since we use huge static mappings to cover the kernel, not pages.

Write kernel log output directly into the VGA buffer or to a serial

This is useful for kernel debugging when your machine crashes very
|
||||
early before the console code is initialized. For normal operation
|
||||
it is not recommended because it looks ugly and doesn't cooperate
|
||||
with klogd/syslogd or the X server. You should normally N here,
|
||||
unless you want to debug such a crash.

Unmap pages from the kernel linear mapping after free_pages().
|

This results in a large slowdown, but helps to find certain types
|

of memory corruptions.
