erst: Read and write to the 'compressed' flag of pstore

2013-08-19T18:53:40+00:00

In pstore write, set the section type to CPER_SECTION_TYPE_DMESG_COMPR
if the data is compressed. In pstore read, read the section type and
update the 'compressed' flag accordingly.

pstore: Add new argument 'compressed' in pstore write callback

2013-08-19T17:18:10+00:00

Addition of new argument 'compressed' in the write call back will
help the backend to know if the data passed from pstore is compressed
or not (In case where compression fails.). If compressed, the backend
can add a tag indicating the data is compressed while writing to
persistent store.

mce: acpi/apei: Soft-offline a page on firmware GHES notification

2013-07-10T18:35:02+00:00

If the firmware indicates in GHES error data entry that the error threshold
has exceeded for a corrected error event, then we try to soft-offline the
page. This could be called in interrupt context, so we queue this up similar
to how we handle memory failure scenarios.
