qla82xx_idc_lock() spins on a certain hardware state until it's updated. At
the end of each spin, if in_interrupt() is true, it does 20 loops of
cpu_relax(). Otherwise, it yields the CPU.
While in_interrupt() is ill-defined and does not provide what the name
suggests, it is not needed here: qla82xx_idc_lock() is always called from
process context. Below is an analysis of its callers, in order of
appearance:
- qla_nx.c: qla82xx_device_bootstrap(), only called by
qla82xx_device_state_handler(), has multiple msleep()s.
- qla_nx.c: qla82xx_need_qsnt_handler(), has one second msleep()
- qla_nx.c: qla82xx_wait_for_state_change(), one second msleep()
- qla_nx.c: qla82xx_need_reset_handler(), can sleep up to 10 seconds
- qla_nx.c: qla82xx_device_state_handler(), has multiple msleep()s
- qla_nx.c: qla82xx_abort_isp(), if it's a qla82xx controller, calls
qla82xx_device_state_handler(), which sleeps. It's also bound to
isp_operations ->abort_isp() hook, where all the callers are in process
context.
- qla_nx.c: qla82xx_beacon_on(), bound to isp_operations ->beacon_on()
hook. That hook is only called once, in a mutex locked context, from
qla2x00_beacon_store().
- qla_nx.c: qla82xx_beacon_off(), bound to isp_operations ->beacon_off()
hook. Like ->beacon_on(), it's only called once, in a mutex locked
context, from qla2x00_beacon_store().
- qla_nx.c: qla82xx_fw_dump(), calls qla2x00_wait_for_chip_reset(), which
has msleep() in a loop. It is bound to isp_operations ->fw_dump()
hook. That hook *is* called from atomic context at qla_isr.c by
multiple interrupt handlers. Nonetheless, it's other controllers
interrupt handlers, and not the qla82xx.
- qla82xx_msix_default() and qla82xx_msix_rsp_q() call
qla24xx_process_response_queue() which doesn't implement the firmware
dumping.
- qla_attr.c: qla2x00_sysfs_write_fw_dump(), and
qla2x00_sysfs_write_reset(), process-context sysfs ->write() hooks.
- qla_os.c: qla2x00_probe_one(). PCI ->probe(), process context.
- qla_os.c: qla2x00_clear_drv_active(), called solely from
qla2x00_remove_one(), which is PCI ->remove() hook, process context.
- qla_os.c: qla2x00_do_dpc(), kthread function, process context.
Remove the in_interrupt() check. Change qla82xx_idc_lock() specification to
a purely process-context function. Mark it with "Context: task, might
sleep".
Change qla82xx_idc_lock() implementation to sleep 100ms, instead of a
schedule(), for each spin. This is more deterministic, and it matches the
other qla models idc_lock() functions.

During cable pull test case, if the port is disconnected for time larger
than devloss timeout, driver does not mark path offline. In such case,
instead of notifying SCSI-ML of loop down, driver goes into endless loop of
device relogin because defer flag is set.
With newer handling of device relogin in driver discovery, defer flag is
now redundant. This patch removes defer flag and cleans up code handling
port lost indication to SCSI-ML.

It assumes the author might have made a mistake in their logic:
if (!a == b) -> if (!(a == b))
Sometimes that is the case; other times, it's just a super convoluted
way of saying 'if (a)' when b = 0:
if (!1 == 0) -> if (0 == 0) -> if (true)
Alternatively:
if (!1 == 0) -> if (!!1) -> if (1)

Surround conditional locking statements with "#ifndef __CHECKER__" /
"#endif" to hide these for the sparse static source code analysis
tool.

The "return QLA_SUCCESS" statement just above the "fw_load_failed"
label cannot be reached, hence remove it. Additionally remove the
"else" keyword since the code block below the if-statement ends
with a return statement.

This patch removes 21 casts between an __iomem pointer type and
another data type but also introduces five new casts (see also
the casts with "__force"). Although this patch does not change
any functionality, IMHO the code with __force casts needs further
review.

Whether htonl() or __constant_htonl() is used, if the argument
is a constant the conversion happens at compile time. Hence leave
out the __constant_ prefix for this and other endianness
conversion functions. This improves source code readability.

Replace the QLA82XX_ADDR_IN_RANGE() and QLA8044_ADDR_IN_RANGE() macros
with the inline function addr_in_range(). This avoids that the compiler
reports the following warning when building with W=1: comparison of
unsigned expression >= 0 is always true.

these routines to check and schedule a PCI-disconnected board from a
centralized place.
