Per request from Matthew Wilcox - using PCI_VENDOR_ATTO.
Add support for ATTO UL4D, they are rebranded 53C1030.
The changes are
1. Adding a new PCI vendor ID in pci table
2. The spi_port_page_2 is in different format than that of LSI generic
spi_port_page_2 and hence mapping code is added.

The Coverity checker noticed that we may overrun a statically allocated
array in drivers/scsi/lpfc/lpfc_sli.c::lpfc_sli_hbqbuf_find().
The case is this; In 'struct lpfc_hba' we have
#define LPFC_MAX_HBQS 4
...
struct lpfc_hba {
...
struct hbq_s hbqs[LPFC_MAX_HBQS];
...
};
But then in lpfc_sli_hbqbuf_find() we have this code
hbqno = tag >> 16;
if (hbqno > LPFC_MAX_HBQS)
return NULL;
if 'hbqno' ends up as exactely 4, then we won't return, and then this
list_for_each_entry(d_buf, &phba->hbqs[hbqno].hbq_buffer_list, list) {
will cause an overflow of the statically allocated array at index 4,
since the valid indices are only 0-3.
I propose this patch, that simply changes the 'hbqno > LPFC_MAX_HBQS'
into 'hbqno >= LPFC_MAX_HBQS' as a possible fix.

- kernels supported
- other files modified (obsolete)
- source comments (obsolete)
- tests to run
- release history (that's what a VCS is for)
- contacting connectcom (the domain has expired and the phone number is
now in use by another organisation)

Use memcpy to initialise eep_config instead of a loop. For
AdvInitFrom38C1600EEP where we need to modify the default EEPROM
configuration, do it after the loop, and do it using the structure
definition, not by finding the right byte. I think it was wrong for
big-endian machines.

n_io_port isn't suitable for advansys because some of the boards have

Register two isa_drivers, one for ISA and one for VLB, in order to
preserve detection order. When deleting advansys_detect, we lose the
last vestiges of the code that limited IO port scanning. This code
has been effectively disabled for many years anyway; I'll restore it
in a module_param later. We also lose the code that placed all ISA PnP
cards into WaitForKey state -- drivers shouldn't be doing this anyway.
The asc_host array goes away too. Also remove some IOADR and other
definitions, such as ASC_NUM_BOARD_SUPPORTED.

unsigned short is too small for sizeof(struct scatterlist) *
min(q->max_hw_segments, q->max_phys_segments).
This fixes memory leak with 4096 segments since 16 (likely sg size
with x86) * 4096 sets sglist_len to zero.
This might not happen without sg chaining support.

Stress-testing and some thought has revealed some places where
asynchronous scanning needs some more attention to locking.
- Since async_scan is a bit, we need to hold the host_lock while
modifying it to prevent races against other CPUs modifying the word
that bit is in. This is probably a theoretical race for the moment,
but other patches may change that.
- The async_scan bit means not only that this host is being scanned
asynchronously, but that all the devices attached to this host are not
yet added to sysfs. So we must ensure that this bit is always in sync.
I've chosen to do this with the scan_mutex since it's already acquired
in most of the right places.
- If the host changes state to deleted while we're in the middle of
a scan, we'll end up with some devices on the host's list which must
be deleted. Add a check to scsi_sysfs_add_devices() to ensure the
host is still running.
- To avoid the async_scan bit being protected by three locks, the
async_scan_lock now only protects the scanning_list.
