ramoops: update parameters only after successful init

2012-01-13T04:13:13+00:00

If a platform device exists on the system, but ramoops fails to attach to
it, the module parameters are overridden before ramoops can fall back and
try to use passed module parameters.  Move update to end of init routine.

ramoops: fix use of rounddown_pow_of_two()

2012-01-13T04:13:13+00:00

The return value of rounddown_pow_of_two wasn't evaluated, so the
operation was a no-op.

kexec: remove KMSG_DUMP_KEXEC

2012-01-13T04:13:11+00:00

KMSG_DUMP_KEXEC is useless because we already save kernel messages inside
/proc/vmcore, and it is unsafe to allow modules to do other stuffs in a
crash dump scenario.

ramoops: update module parameters

2011-08-04T00:25:21+00:00

Update the module parameters when platform data is used.  This means
that they can be read from /sys/module/ramoops/parameters in order to
parse the memory area.

ramoops: fix compile failure on parisc

2011-07-30T06:41:09+00:00

Fixes this:

  drivers/char/ramoops.c: In function 'ramoops_init':
  drivers/char/ramoops.c:221: error: implicit declaration of function 'IS_ERR'
  drivers/char/ramoops.c:222: error: implicit declaration of function 'PTR_ERR'

If it actually builds on other platforms, it's probably getting
linux/err.h via some other #include.

ramoops: make record_size a module parameter

2011-07-26T23:49:46+00:00

The size of the dump is currently set using the RECORD_SIZE macro which
is set to a page size.  This patch makes the record size a module
parameter and allows it to be set through platform data as well to allow
larger dumps if needed.

ramoops: move dump_oops into platform data

2011-07-26T23:49:45+00:00

The platform driver currently allows setting the mem_size and
mem_address.

ince dump_oops is also a module parameter it would be more consistent if
it could be set through platform data as well.
