*	[PPC440SPe] Convert machine check exceptions handling	Grzegorz Bernacki	2007-09-07	1	-14/+2
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Convert using fixup mechanism to suppressing MCK for the duration of config read/write transaction: while fixups work fine with the case of a precise exception, we identified a major drawback with this approach when there's an imprecise case. In this scenario there is the following race condition: the fixup is (by design) set to catch the instruction following the one actually causing the exception; if an interrupt (e.g. decrementer) happens between those two instructions, the ISR code is executed before the fixup handler the machine check is no longer protected by the fixup handler as it appears as within the ISR code. In consequence the fixup approach is being phased out and replaced with explicit suppressing of MCK during a PCIe config read/write cycle. Signed-off-by: Grzegorz Bernacki <gjb@semihalf.com>
*	[ppc440SPe] Graceful recovery from machine check during PCIe configuration	Grzegorz Bernacki	2007-08-02	1	-2/+17
\| \| \| \| \| \| \| \| \| \| \|	During config transactions on the PCIe bus an attempt to scan for a non-existent device can lead to a machine check exception with certain peripheral devices. In order to avoid crashing in such scenarios the instrumented versions of the config cycle read routines are introduced, so the exceptions fixups framework can gracefully recover.
