Lee Jones ce7e0a84e5 scsi: qedf: Demote obvious misuse of kerneldoc to standard comment blocks

Chad Dupuis 3e2c11b3fb scsi: qedf: Simplify s/g list mapping
When mapping the pages from a scatter/gather list from the SCSI layer we
only need to follow these rules:

 - Max SGEs for each I/O request is 256
 - No size limit on each SGE
 - No need to split OS provided SGEs to 4K before sending to firmware.
 - Slow SGE is applicable only when:
   - There are > 8 SGEs and any middle SGE is less than a page size (4K)

Make necessary changes so that driver follows these rules. Applicable only
for Write requests (not for Read requests). No need to check SGE address
alignment requirements (first, middle or last) before declaring slow SGE.

Greg Kroah-Hartman 26febfb38c scsi: qedf: no need to check return value of debugfs_create functions
When calling debugfs functions, there is no need to ever check the return
value.  The function can work or not, but the code logic should never do
something different based on this.

Linus Torvalds 5f85942c2e SCSI misc on 20180610
This is mostly updates to the usual drivers: ufs, qedf, mpt3sas, lpfc,
 xfcp, hisi_sas, cxlflash, qla2xxx.  In the absence of Nic, we're also
 taking target updates which are mostly minor except for the tcmu
 refactor. The only real core change to worry about is the removal of
 high page bouncing (in sas, storvsc and iscsi).  This has been well
 tested and no problems have shown up so far.

Arnd Bergmann d9ea463a1c scsi: qedf: fix LTO-enabled build
The prototype for qedf_dbg_fops/qedf_debugfs_ops doesn't match the definition,
which causes the final link to fail with link-time optimizations:

drivers/scsi/qedf/qedf_main.c:34: error: type of 'qedf_dbg_fops' does not match original declaration [-Werror=lto-type-mismatch]
 extern struct file_operations qedf_dbg_fops;

drivers/scsi/qedf/qedf_debugfs.c:443: note: 'qedf_dbg_fops' was previously declared here
 const struct file_operations qedf_dbg_fops[] = {

drivers/scsi/qedf/qedf_main.c:33: error: type of 'qedf_debugfs_ops' does not match original declaration [-Werror=lto-type-mismatch]
 extern struct qedf_debugfs_ops qedf_debugfs_ops;

drivers/scsi/qedf/qedf_debugfs.c:102: note: 'qedf_debugfs_ops' was previously declared here
 struct qedf_debugfs_ops qedf_debugfs_ops[] = {

This corrects the prototype and moves it into a shared header file where it
belongs. The file operations can also be marked 'const' like the
qedf_debugfs_ops.

Kees Cook efacae6d4c scsi: qedi: qedf: Use designated initializers
Prepare to mark sensitive kernel structures for randomization by making
sure they're using designated initializers. These were identified during
allyesconfig builds of x86, arm, and arm64, with most initializer fixes
extracted from grsecurity.

For these cases, terminate the list with { }, which will be zero-filled,
instead of undesignated NULLs.
