The older smsc911x driver made platform data optional, but the newer one
always requires it, so add proper settings to the BF548-EZKIT.Signed-off-by: Mike Frysinger

The SPI flash on the BF518F-EZBRD board is actually hooked up to CS2,
not CS1, so make sure the resources are correct.URL: http://blackfin.uclinux.org/gf/tracker/5220

The Blackfin SPI driver can be driven by an IRQ now, so declare it in
the board resources.Signed-off-by: Yi Li

Before we configure the early UART, check to make sure we are running on
the expected processor - otherwise, we cause problems by configuring pins
that don't exist (and causing an infinite loop of faults).Signed-off-by: Robin Getz

When a low priority interrupt (like ethernet) is triggered between 2 high
priority IPI messages, a deadlock in disable_irq() is hit by the second
IPI handler. This is because the second IPI message is queued within the
first IPI handler, but the handler doesn't process all messages, and new
ones are inserted rather than appended. So now we process all the pending
messages, and append new ones to the pending list.URL: http://blackfin.uclinux.org/gf/tracker/5226

The IRQ functions take an "unsigned long" flags variable, not any other
type, so fix the places where we use "int" or "long".Signed-off-by: Mike Frysinger
-
Rather than maintain a duplicate list of valid exceptions we can take in
the kernel both in the first if() check and the switch() check, delay the
oops check to after the switch(). All valid exceptions will have returned
by this point leaving only the invalid ones.Signed-off-by: Mike Frysinger
-
The trap_c() code pushes the hardware trace status onto the stack, but
doesn't always restore it when returning from some trap code paths. So
unify the exit code paths to all head to the end of the function.Signed-off-by: Mike Frysinger

The KGDB code uses this when switching processors to make sure the icache
is in a valid state.Signed-off-by: Sonic Zhang

Since the compiled-for cpu revision can be significant, include it in the

All other arches do this, and some places like the net/scsi code will fail
as modules without them.Signed-off-by: Mike Frysinger

We don't need to handle CPLB protection violations unless we are running
with the MPU on. Fix the entry code to call common trap_c, and remove the
code which is never run. This allows the traps test suite to run on older
boards with the MPU disabled.URL: http://blackfin.uclinux.org/gf/tracker/5129

git commit 0a0c5168 "PM: Introduce functions for suspending and resuming
device interrupts" introduced some helper functions. However these
functions are only available for architectures which support
GENERIC_HARDIRQS.Other architectures will see this build error:
drivers/built-in.o: In function `sysdev_suspend':
(.text+0x15138): undefined reference to `check_wakeup_irqs'
drivers/built-in.o: In function `device_power_up':
(.text+0x1cb66): undefined reference to `resume_device_irqs'
drivers/built-in.o: In function `device_power_down':
(.text+0x1cb92): undefined reference to `suspend_device_irqs'To fix this add some empty inline functions for !GENERIC_HARDIRQS.

The *_nvs_* routines in swsusp.c make use of the io*map()
functions, which are only provided for HAS_IOMEM, thus
breaking compilation if HAS_IOMEM is not set. Fix this
by moving the *_nvs_* routines into hibernate_nvs.c, which
is only compiled if HAS_IOMEM is set.[rjw: Change the name of the new file to hibernate_nvs.c, add the

Move the suspend to RAM and standby code from kernel/power/main.c
to two separate files, kernel/power/suspend.c containing the basic
functions and kernel/power/suspend_test.c containing the automatic
suspend test facility based on the RTC clock alarm.There are no changes in functionality related to these modifications.

This patch reworks the platform driver code for legacy
suspend and resume to avoid installing callbacks in
struct device_driver. A warning is also added telling
users to update the platform driver to use dev_pm_ops.The functions platform_legacy_suspend()/resume() directly
call suspend and resume callbacks in struct platform_driver
instead of wrapping things in platform_drv_suspend()/resume().Signed-off-by: Magnus Damm

A future patch is going to modify the memory shrinking code so that
it will make memory allocations to free memory instead of using an
artificial memory shrinking mechanism for that. For this purpose it
is convenient to move swsusp_shrink_memory() from
kernel/power/swsusp.c to kernel/power/snapshot.c, because the new
memory-shrinking code is going to use things that are local to
kernel/power/snapshot.c .[rev. 2: Make some functions static and remove their headers from

Remove the ->suspend_late() and ->resume_early() callbacks

This patch (as1241) renames a bunch of functions in the PM core.
Rather than go through a boring list of name changes, suffice it to
say that in the end we have a bunch of pairs of functions:device_resume_noirq dpm_resume_noirq
device_resume dpm_resume
device_complete dpm_complete
device_suspend_noirq dpm_suspend_noirq
device_suspend dpm_suspend
device_prepare dpm_preparein which device_X does the X operation on a single device and dpm_X
invokes device_X for all devices in the dpm_list.In addition, the old dpm_power_up and device_resume_noirq have been
combined into a single function (dpm_resume_noirq).Lastly, dpm_suspend_start and dpm_resume_end are the renamed versions
of the former top-level device_suspend and device_resume routines.Signed-off-by: Alan Stern

Rename the functions performing "_noirq" dev_pm_ops
operations from device_power_down() and device_power_up()
to device_suspend_noirq() and device_resume_noirq().The new function names are chosen to show that the functions
are responsible for calling the _noirq() versions to finalize
the suspend/resume operation. The current function names do
not perform power down/up anymore so the names may be misleading.Global function renames:
- device_power_down() -> device_suspend_noirq()
- device_power_up() -> device_resume_noirq()Static function renames:
- suspend_device_noirq() -> __device_suspend_noirq()
- resume_device_noirq() -> __device_resume_noirq()Signed-off-by: Magnus Damm
