fusion: remove dead MTRR code

2015-06-13T15:44:14+00:00

If and when this gets enabled the driver could should split up IO memory space properly and that is quite a bit of work. Just remove the uncommented dead MTRR code then. There are a few motivations for this: a) Take advantage of PAT when available b) Help bury MTRR code away, MTRR is architecture specific and on x86 its replaced by PAT c) Help with the goal of eventually using _PAGE_CACHE_UC over _PAGE_CACHE_UC_MINUS on x86 on ioremap_nocache() (see commit de33c442e titled "x86 PAT: fix performance drop for glx, use UC minus for ioremap(), ioremap_nocache() and pci_mmap_page_range()") Signed-off-by: Luis R.

mptfusion: make adapter prod_name[] a pointer

2014-07-25T21:16:58+00:00

The struct _MPT_ADAPTER doesn't need a full copy of the product string, so prod_name can point to the string literal storage that the driver already provides. Avoids the following smatch warning: drivers/message/fusion/mptbase.c:2858 MptDisplayIocCapabilities() warn: this array is probably non-NULL.

scsi: use 64-bit LUNs

2014-07-17T20:07:37+00:00

The SCSI standard defines 64-bit values for LUNs, and large arrays employing large or hierarchical LUN numbers become more and more common. So update the linux SCSI stack to use 64-bit LUN numbers.

[SCSI] fusion: ensure NUL-termination of MptCallbacksName elements

2011-12-15T06:57:29+00:00

Using strlcpy instead of memcpy makes the strlen() calls superfluous and also ensures zero-termination of the copied string. At the same time get rid of the magic constant 50. Actually, I can't see why copying the callback name is necessary instead of simply storing a pointer to it (just like to the callback function itself), but that goes beyond the scope of this fix.
