libsas event notifiers required an extension where gfp_t flags must be
explicitly passed. For bisectability, a temporary _gfp() variant of such
functions were added. All call sites then got converted use the _gfp()
variants and explicitly pass GFP context. Having no callers left, the
original libsas notifiers were then modified to accept gfp_t flags by
default.
Switch back to the original libas API, while still passing GFP context.
The libsas _gfp() variants will be removed afterwards.

LLDDs report events to libsas with .notify_port_event and .notify_phy_event
callbacks.
These callbacks are fixed and so there is no reason why the functions
cannot be called directly, so do that.
This neatens the code slightly, makes it more obvious, and reduces function
pointer usage, which is generally a good thing. Downside is that there are
2x more symbol exports.

PCI helper functions such as pci_enable/disable_device(),
pci_save/restore_state(), pci_set_power_state(), etc. were used by the
legacy framework to perform standard operations related to PCI PM.
This driver is using the generic framework and thus calls for those
functions should be dropped as those tasks are now performed by the PCI
core.

The current codebase makes use of the zero-length array language extension
to the C90 standard, but the preferred mechanism to declare variable-length
types such as these ones is a flexible array member[1][2], introduced in
C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning in
case the flexible array does not occur last in the structure, which will
help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by this
change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

The ata_sas_scsi_ioctl() function implements a number of HDIO_* commands
for SCSI devices, it is used by all libata drivers as well as a few
drivers that support SAS attached SATA drives.
The only command that is not safe for compat ioctls here is
HDIO_GET_32BIT. Change the implementation to check for in_compat_syscall()
in order to do both cases correctly, and change all callers to use it
as both native and compat callback pointers, including the indirect
callers through sas_ioctl and ata_scsi_ioctl.

scsi_mq_setup_tags(), which is called by scsi_add_host(), calculates the
command size to allocate based on the prot_capabilities. In the isci
driver, scsi_host_set_prot() is called after scsi_add_host() so the command
size gets calculated to be smaller than it needs to be. Eventually,
scsi_mq_init_request() locates the 'prot_sdb' after the command assuming it
was sized correctly and a buffer overrun may occur.
However, seeing blk_mq_alloc_rqs() rounds up to the nearest cache line
size, the mistake can go unnoticed.
The bug was noticed after the struct request size was reduced by commit
9d037ad707 ("block: remove req->timeout_list")
Which likely reduced the allocated space for the request by an entire cache
line, enough that the overflow could be hit and it caused a panic, on boot,
at:
RIP: 0010:t10_pi_complete+0x77/0x1c0
Call Trace:
<IRQ>
sd_done+0xf5/0x340
scsi_finish_command+0xc3/0x120

__do_softirq+0xa1/0x2e6
irq_exit+0xbc/0xd0
call_function_single_interrupt+0xf/0x20
</IRQ>
sd_done() would call scsi_prot_sg_count() which reads the number of
entities in 'prot_sdb', but seeing 'prot_sdb' is located after the end of
the allocated space it reads a garbage number and erroneously calls
t10_pi_complete().
To prevent this, the calls to scsi_host_set_prot() are moved into
isci_host_alloc() before the call to scsi_add_host(). Out of caution, also
move the similar call to scsi_host_set_guard().
