[PATCH v4 0/7] spi: Add support for panic mem writes

[Paul Cercueil]

Hi,

Here is the v4 of my patchset that updates the MTD spi-nor code as well
as the spi-mem code, to add support for panic mem writes to a memory
partition configured as pstore.

This revision adds a workaround in mtd/spi-nor to avoid a call to
kmalloc(), and fixes a kernel doc mismatch.

Changelog:

 - [2/7]:
        - Also update kernel doc for new 'timeout_ms' parameter

 - [3/7]:
        - kmalloc() is not safe in panic context; reuse boucebuf instead

 - Patch [1/7] and 4->7 unchanged since v3.

Cheers,
-Paul
