platform/x86: Consistently select LEDS Kconfig options

Currently the x86 platform devices are not consistent about selecting
or depending on the LEDs Kconfig variables, and this inconsistency
leads to Kconfig getting upset and refusing to offer LEDs (even on
non-x86 platforms):

drivers/platform/x86/Kconfig:422:error: recursive dependency detected!
drivers/platform/x86/Kconfig:422:       symbol EEEPC_WMI depends on ACPI_WMI
drivers/platform/x86/Kconfig:438:       symbol ACPI_WMI is selected by ACER_WMI
drivers/platform/x86/Kconfig:18:        symbol ACER_WMI depends on LEDS_CLASS
drivers/leds/Kconfig:10:        symbol LEDS_CLASS is selected by EEEPC_WMI

Fix this by always selecting rather than depending on the symbols as
slightly more drivers use this approach already and it seems more
user friendly.

Yi Li [Thu, 17 Dec 2009 08:20:32 +0000 (08:20 +0000)]
Blackfin: SMP: rewrite IPI handling to avoid memory allocation

Currently, sending an interprocessor interrupt (IPI) requires building up
a message dynamically which means memory allocation.  But often times, we
will want to send an IPI in low level contexts where allocation is not
possible which may lead to a panic().  So create a per-cpu static array
for the message queue and use that instead.

Further, while we have two supplemental interrupts, we are currently only
using one of them.  So use the second one for the most common IPI message
of all -- smp_send_reschedule().  This avoids ugly contention for locks
which in turn would require an IPI message ...

In general, this improves SMP performance, and in some cases allows the
SMP port to work in places it wouldn't before.  Such as the PREEMPT_RT
state where the slab is protected by a per-cpu spin lock.  If the slab
kmalloc/kfree were to put the task to sleep, and that task was actually
the IPI handler, then the system falls down yet again.

After running some various stress tests on the system, the static limit
of 5 messages seems to work.  On the off chance even this overflows, we
simply panic(), and we can review that scenario to see if the limit needs
to be increased a bit more.

serial: bfin_5xx: move resources into board files

Rather than maintain Kconfig entries where people have to enter raw
numbers and hardcode lists of addresses/pins in the driver itself,
push it all to platform resources.  This lets us simplify the driver,
the Kconfig, and gives board porters greater flexibility.

In the process, we need to also start supporting the early platform
interface.  Not a big deal, but it causes the patch to be bigger than
a simple resource relocation.

Blackfin: clean up mach header includes

The main asm/blackfin.h header will pull in mach/blackfin.h to get
all the fun Blackfin defines.  So having any of the sub-mach headers
trying to include asm/blackfin.h makes no sense -- punt it.

The mach/blackfin.h header takes care of including the part-specific
def headers which in turn will include any other needed def file.
Similarly, it takes care of pulling in the part-specific cdef header.
So move this logic out of the blackfin.h when necessary.

Further, make sure the cdef headers do not waste time including the
def headers again.

Since all parts need the common def/cdef headers, move this logic
out of the part-specific headers and into the mach/blackfin.h file.

Finally, we need to split the BF539 def header since the BF538 does
not have MXVR and we don't want to expose those MMRs.

So now all parts should have the same behavior:
mach/blackfin.h
asm/def_LPBlackfin.h
part-specific def.h
if ! asm
asm/cdef_LPBlackfin.h
part-specific cdef.h
And the sub def/cdef headers only tail into what they need.
