Currently the SigmaDSP firmware loader only works correctly on little-endian systems. Fix this by using the proper endianess conversion functions.

The firmware header is not part of the CRC, so skip it. Otherwise the firmware will be rejected due to non-matching CRCs.

The SigmaDSP firmware loader currently does not perform enough boundary size checks when processing the firmware. As a result it is possible that a malformed firmware can cause an out of bounds memory access. This patch adds checks which ensure that both the action header and the payload are completely inside the firmware data boundaries before processing them.

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/aegl/linux: efivars: add missing parameter to efi_pstore_read()
In the case where CONFIG_PSTORE=n, the function efi_pstore_read() doesn't have the correct list of parameters. This patch provides a definition of efi_pstore_read() with 'char **buf' added to fix this warning: "drivers/firmware/efivars.c:609: warning: initialization from". problem introduced in commit f6f8285132907757ef84ef8dae0a1244b8cde6ac Signed-off-by: Christoph Fritz <chf.fritz@googlemail.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/aegl/linux: pstore: pass allocated memory region back to caller
The buf_lock cannot be held while populating the inodes, so make the backend pass forward an allocated and filled buffer instead. This solves the following backtrace. The effect is that "buf" is only ever used to notify the backends that something was written to it, and shouldn't be used in the read path. To replace the buf_lock during the read path, isolate the open/read/close loop with a separate mutex to maintain serialized access to the backend. Note that is is up to the pstore backend to cope if the (*write)() path is called in the middle of the read path.

The current implementation of dmi_name_in_vendors() is an invitation to lazy coding and false positives [1]. Searching for a string in 8 know what you're looking for, so you should know where to look. strstr isn't fast, especially when it fails, so we should avoid calling it when it just can't succeed. Looking at the current users of the function, it seems clear to me that they are looking for a system or board vendor name, so let's limit dmi_name_in_vendors to these two DMI fields. This much better matches the function name, BTW. [1] We currently have code looking for short names in DMI data, such as "IBM", "ASUS" or "Acer". I let you guess what will happen the day other vendors ship products named, for example, "SCHREIBMEISTER", "PEGASUS" or "Acerola".
