* Now there is some trickery with the data returned by OPAL
* as it's the desired data right justified in a 32-bit BE
* word.
*
* This is a very bad interface and I'm to blame for it :-(
*
* So we can't just apply a 32-bit swap to what comes from OPAL,
* because user space expects the *bytes* to be in their proper
* respective positions (ie, LPC position).
*
* So what we really want to do here is to shift data right
* appropriately on a LE kernel.
*
* IE. If the LPC transaction has bytes B0, B1, B2 and B3 in that
* order, we have in memory written to by OPAL at the "data"
* pointer:
*
* Bytes: OPAL "data" LE "data"
* 32-bit: B0 B1 B2 B3 B0B1B2B3 B3B2B1B0
* 16-bit: B0 B1 0000B0B1 B1B00000
* 8-bit: B0 000000B0 B0000000
*
* So a BE kernel will have the leftmost of the above in the MSB
* and rightmost in the LSB and can just then "cast" the u32 "data"
* down to the appropriate quantity and write it.
*
* However, an LE kernel can't. It doesn't need to swap because a
* load from data followed by a store to user are going to preserve
* the byte ordering which is the wire byte order which is what the
* user wants, but in order to "crop" to the right size, we need to
* shift right first.

Disable the device coredump mechanism despite drivers wanting to
use it; this allows for more sensitive systems or systems that
don't want to ever access the information to not have the code,
nor keep any data.
This option controls if the device coredump mechanism is available or
not; if disabled, the mechanism will be omitted even if drivers that
can use it are enabled.
Say 'N' for more sensitive systems or systems that don't want
to ever access the information to not have the code, nor keep any
