2009-06-22Blackfin: only build show_interrupts() when procfs is enabledMike Frysinger
Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-06-22Blackfin: redo handling of bad irqsMike Frysinger
With the common IRQ code initializing much more of the irq_desc state, we can't blindly initialize it ourselves to the local bad_irq state. If we do, we end up wrongly clobbering many fields. So punt most of the bad irq code as the common layers will handle the default state, and simply call handle_bad_irq() directly when the IRQ we are processing is invalid.

2009-06-22Blackfin: update anomaly listsMike Frysinger
Update anomaly headers to match latest released anomaly sheets. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-06-22Blackfin: bf533-ezkit: add resources for FISP devicesMike Frysinger
The BF533-EZKIT has two Flash In-System Programming devices hooked up to the async memory bus, so add resources for the primary flashes and the SRAMs on the devices. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-06-22Blackfin: bf518f-ezbrd: update DSA resourcesMike Frysinger
The common DSA code changed structure layout, so update the BF518F-EZBRD resources accordingly. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-06-22Blackfin: unify memory region checks between kgdb and trapsMike Frysinger
The kgdb (in multiple places) and traps code developed pretty much identical checks for how to access different regions of the Blackfin memory map, but each wasn't 100%, so unify them to avoid duplication, bitrot, and bugs with edge cases. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-06-18Blackfin: only build irqpanic.c when neededMike Frysinger
The irq_panic function is only used when CONFIG_DEBUG_ICACHE_CHECK is enabled, so move the conditional build to the Makefile rather than wrapping all of the contents of the file. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-06-18Blackfin: pull in asm/io.h in ksyms for prototypesMike Frysinger
Make sure we pull in asm/io.h when exporting symbols for the I/O functions so we don't end up with a build failure due to missing prototypes. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-06-18Blackfin: use common test_bit() rather than __test_bit()Mike Frysinger
Convert to test_bit() as that is what pretty much everyone uses and allows us to migrate asm/bitops.h to the asm-generic version. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-06-16kmap_types: make most arches use generic header fileRandy Dunlap
Convert most arches to use asm-generic/kmap_types.h. Move the KM_FENCE_ macro additions into asm-generic/kmap_types.h, controlled by __WITH_KM_FENCE from each arch's kmap_types.h file. Would be nice to be able to add custom KM_types per arch, but I don't yet see a nice, clean way to do that. Built on x86_64, i386, mips, sparc, alpha(tonyb), powerpc(tonyb), and 68k(tonyb). Note: avr32 should be able to remove KM_PTE2 (since it's not used) and then just use the generic kmap_types.h file. Get avr32 maintainer approval.

2009-06-16mm: consolidate init_mm definitionAlexey Dobriyan
* create mm/init-mm.c, move init_mm there * remove INIT_MM, initialize init_mm with C99 initializer * unexport init_mm on all arches: init_mm is already unexported on x86. One strange place is some OMAP driver (drivers/video/omap/) which won't build modular, but it's already wants get_vm_area() export. Somebody should look there.

2009-06-13Blackfin: improve CLKIN_HZ config defaultMike Frysinger
Most boards use 25000000 as the default HZ, so rather than add a whole bunch more boards, make it the default for everyone. This also fixes randconfig builds as there was no default before. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-06-13Blackfin: move custom sections into sections.hMike Frysinger
The Blackfin arch has a bunch of custom section markings for its on-chip regions, but they aren't declared in the right header. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-06-13Blackfin: punt unused/wrong mutex-dec.hMike Frysinger
Looks like the mutex-dec.h header file was incorrectly copied into the Blackfin asm path. Nothing uses it, so punt it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-06-13Blackfin: add support for irqflagsMike Frysinger
This converts the irq handling in the Blackfin arch from the old irq.h / system.h method to the new irqflags.h. A stepping stone on the way to other tracing functionality. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-06-13Blackfin: add support for bzip2/lzma compressed kernel imagesMike Frysinger

2009-06-13Blackfin: bf548-ezkit: update smsc911x resourcesMike Frysinger
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 <vapier@gentoo.org>

2009-06-13Blackfin: do not configure the UART early if on wrong processorRobin Getz
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).

2009-06-13Blackfin: fix deadlock in SMP IPI handlerSonic Zhang
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.

2009-06-13Blackfin: fix flag storage for irq funcsMike Frysinger
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 <vapier@gentoo.org>
2009-06-13Blackfin: push down exception oops checkingMike 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 <vapier@gentoo.org>
2009-06-13Blackfin: fix trap_c() exit pathsMike 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 <vapier@gentoo.org>
