2007-10-21Blackfin arch: Fix up /proc/cpuinfo so it is like everyone elseRobin Getz1-39/+61
Fix up /proc/cpuinfo so it is like everyone else, and gets parsed by various applications properly. Still needs some tweaking on parts without full L1 sram, like 532, 531, so it doesn't print out L1 bank info that doesn't exist.

2007-10-22Blackfin arch: force irq_flags into the .data sectionMike Frysinger2-2/+14
force irq_flags into the .data section by initializing it to the hardware masks that cannot be disabled. this way if we use irq enable/disable functions before the .bss has been zeroed out (as does our l1 relocate/dma functions), we dont hit a problem where bss contains bogus crap.

2007-10-20typo fixesMatt LaPlante1-35/+36
Most of these fixes were already submitted for old kernel versions, and were approved, but for some reason they never made it into the releases. Because this is a consolidation of a couple old missed patches, it touches both Kconfigs and documentation texts.

2007-10-19Combine instrumentation menus in kernel/Kconfig.instrumentationMathieu Desnoyers2-30/+1
Quoting Randy: "It seems sad that this patch sources Kconfig.marker, a 7-line file, 20-something times. Yes, you (we) don't want to put those 7 lines into 20-something different files, so sourcing is the right thing. However, what you did for avr32 seems more on the right track to me: make _one_ Instrumentation support menu that includes PROFILING, OPROFILE, KPROBES, and MARKERS and then use (source) that in all of the arches."

2007-10-18PM: Rework struct platform_suspend_opsRafael J. Wysocki1-48/+5
There is no reason why the .prepare() and .finish() methods in 'struct platform_suspend_ops' should take any arguments, since architectures don't use these methods' argument in any practically meaningful way (ie. either the target system sleep state is conveyed to the platform by .set_target(), or there is only one suspend state supported and it is indicated to the PM core by .valid(), or .prepare() and .finish() aren't defined at all).  There also is no reason why .finish() should return any result.

2007-10-18PM: Rename struct pm_ops and related thingsRafael J. Wysocki1-2/+2
The name of 'struct pm_ops' suggests that it is related to the power management in general, but in fact it is only related to suspend.  Moreover, its name should indicate what this structure is used for, so it seems reasonable to change it to 'struct platform_suspend_ops'.  In that case, the name of the global variable of this type used by the PM core and the names of related functions should be changed accordingly.

2007-10-18PM: Move definition of struct pm_ops to suspend.hRafael J. Wysocki1-1/+1
Move the definition of 'struct pm_ops' and related functions from <linux/pm.h> to <linux/suspend.h> . There are, at least, the following reasons to do that: * 'struct pm_ops' is specifically related to suspend and not to the power management in general. * As long as 'struct pm_ops' is defined in <linux/pm.h>, any modification of it causes the entire kernel to be recompiled, which is unnecessary and annoying. * Some suspend-related features are already defined in <linux/suspend.h>, so it is logical to move the definition of 'struct pm_ops' into there. * 'struct hibernation_ops', being the hibernation-related counterpart of 'struct pm_ops', is defined in <linux/suspend.h> .

This patch replace use of AFLAGS with KBUILD_AFLAGS all over the tree.

This patch replace use of CFLAGS with KBUILD_CFLAGS all over the tree and enabling one to use: make CFLAGS=... to specify additional gcc commandline options. One usecase is when trying to find gcc bugs but other use cases has been requested too. Patch was tested on following architectures: alpha, arm, i386, x86_64, mips, sparc, sparc64, ia64, m68k Test was simple to do a defconfig build, apply the patch and check that nothing got rebuild.

- flush/inv the correct range - dmacopy test failed when policy is write_back - invalidate before dma http://blackfin.uclinux.org/gf/project/uclinux-dist/tracker/?action=TrackerItemEdit&tracker_item_id=3367 It's the cache invalidate what is causing the issue. There is no invalidate only instruction it's always: FLUSHINV So when we "invalidate" after the DMA we might (do) overwrite freshly dma'ed data by dirty Cache WB content.
