commit 1873bb8115e678ad9fd0aac9dbbc68383bc36e06 upstream.
The current code mis-calculates the ramoops header size, leading to an
overflow over the next record at best, or over a non-allocated region at
worst. Fix that calculation.

char drivers: RAM oops/panic logger2010-05-27T16:12:50+00:00Marco Stornellimarco.stornelli@gmail.com2010-05-26T21:43:54+00:00urn:sha1:56d611a04fb2db77334e06274de4daed92e2c626
Ramoops, like mtdoops, can log oops/panic information but in RAM. It can
be used with persistent RAM for systems without flash support. In
addition, for this systems, with this driver, it's no more needed add to
the kernel the mtd subsystem with advantage in footprint.
It can be used in a very easy way with persistent RAM for systems without
flash support. For these systems, with this driver, it is no longer
required to cinlude mtd subsystem with an advantage in footprint. In
addition, you can save flash space and store this information only in RAM.
