Subject: [PATCH 00/13] EEH refactoring 2

From: Sam Bobroff <[email-masked]>

Hello everyone,

Here is a second, somewhat deeper, set of cleanups for the EEH code
(mostly eeh_drver.c).

These changes are not intended to significantly alter the actual processing,
but rather to improve the readability and maintainability of the code. They are
subjective by nature so I would appreciate comments and suggestions.

The earlier changes are mostly to support the last patch, where we're finally
able to use a common infrastructure for the reporting functions (basically
wrappers around the driver's handlers). This allows removal of a fair bit of
code, and the easy addition of some useful messaging which should make future
maintenance easier (as an example, a recent fix in this area "powerpc/eeh: Fix
race with driver un/bind" would have required adding two lines rather than
42+/26-).

Cheers,
Sam.
