The recent irq cleanups for arch/arm/mach-integrator/time.c and drivers/char/mwave/tp3780i.c changed the request_irq() dev_id parameter, but neglected to change the matching free_irq() parameter, thus creating a bug upon irq de-registration.

2008-04-24[POWERPC] Add CONFIG_PPC_PSERIES_DEBUG to enable debugging for platforms/pseriesMichael Ellerman
Add a DEBUG config setting which turns on all (most) of the debugging under platforms/pseries. To have this take effect we need to remove all the #undef DEBUG's, in various files. We leave the #undef DEBUG in platforms/pseries/lpar.c, as this enables debugging printks from the low-level hash table routines, and tends to make your system unusable. If you want those enabled you still have to turn them on by hand. Also some of the RAS code has a DEBUG block which causes a functional change, so I've keyed this off a different (non-existant) debug #define. This is only enabled if you have PPC_EARLY_DEBUG enabled also. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>

2008-04-24[POWERPC] Register udbg console early on pseries LPARMichael Ellerman
On pseries LPAR we can call the udbg routines, and the udbg console very early. So mark the udbg console as safe to call early in boot, and register the udbg console as soon as the udbg routines are hooked up. This allows platforms/pseries code to use printk() and pr_debug() rather than needing to call udbg_printf() directly for early debugging. This is nice because a) it's standard, b) it goes via the printk buffer, and c) you can get printk time stamps.

2008-04-24[POWERPC] Mark udbg console as CON_ANYTIME, ie. callable early in bootMichael Ellerman
The udbg console should be safe to call basically at any time after boot. It does not need any per-cpu resources or for the cpu to be online, as long as there is a udbg_putc routine hooked up it should work. So mark it as CON_ANYTIME.

2008-04-24[POWERPC] Set udbg_console index to 0Michael Ellerman
Because the udbg_console has CON_ENABLED set, it's possible that when we register it with the console code the index won't be set. This leads to slightly confusing boot messages like: [ 0.000000] console [udbg-1] enabled We could remove CON_ENABLED, but we don't want to do that, we always want the udbg console to be activated, even if the user specified some other console on the command line. The simplest fix seems to be just to set the index to 0 by hand. There is no issue with duplicate udbg consoles, as we guard against registering multiple times in register_early_udbg_console().

2008-04-24[POWERPC] Discourage people from fiddling with kernel data from prom_initMichael Ellerman
As BenH said the other day, it is an "accident" that prom_init.o is linked with the rest of the kernel. The truth is a little more subtle, prom_init isn't truly bootloader, it does access kernel data in a few places. What we can do is discourage people from adding new code that accesses data outside of prom_init. And hence this patch; from the script: # This script checks prom_init.o to see what external symbols it # is using, if it finds symbols not in the whitelist it returns # an error. The point of this is to discourage people from # intentionally or accidentally adding new code to prom_init.c # which has side effects on other parts of the kernel.

2008-04-24[POWERPC] Port fixmap from x86 and use for kmap_atomicKumar Gala
The fixmap code from x86 allows us to have compile time virtual addresses that we change the physical addresses of at run time. This is useful for applications like kmap_atomic, PCI config that is done via direct memory map, kexec/kdump. We got ride of CONFIG_HIGHMEM_START as we can now determine a more optimal location for PKMAP_BASE based on where the fixmap addresses start and working back from there. Additionally, the kmap code in asm-powerpc/highmem.h always had debug enabled. Moved to using CONFIG_DEBUG_HIGHMEM to determine if we should have the extra debug checking.

2008-04-24[POWERPC] 85xx: Add support for relocatable kernel (and booting at non-zero)Kumar Gala
Added support to allow an 85xx kernel to be run from a non-zero physical address (useful for cooperative asymmetric multiprocessing situations and kdump). The support can be configured at compile time by setting CONFIG_PAGE_OFFSET, CONFIG_KERNEL_START, and CONFIG_PHYSICAL_START as desired. Alternatively, the kernel build can set CONFIG_RELOCATABLE. Setting this config option causes the kernel to determine at runtime the physical addresses of CONFIG_PAGE_OFFSET and CONFIG_KERNEL_START. If CONFIG_RELOCATABLE is set, then CONFIG_PHYSICAL_START has no meaning. However, CONFIG_PHYSICAL_START will always be used to set the LOAD program header physical address field in the resulting ELF image. Currently we are limited to running at a physical address that is a multiple of 256M. This is due to how we map TLBs to cover lowmem. This should be fixed to allow 64M or maybe even 16M alignment in the future. It is considered an error to try and run a kernel at a non-aligned physical address. All the magic for this support is accomplished by proper initialization of the kernel memory subsystem and use of ARCH_PFN_OFFSET. The use of ARCH_PFN_OFFSET only affects normal memory and not IO mappings. ioremap uses map_page and isn't affected by ARCH_PFN_OFFSET. /dev/mem continues to allow access to any physical address in the system regardless of how CONFIG_PHYSICAL_START is set.

Commit d04ceb3fc294ea2c4f538a04343f3a473953a3b0 moved phys_addr_t definitions to include/asm-powerpc/types.h. However, arch/ppc 440 builds had a duplicate definition in include/asm-ppc/mmu.h that caused the build to fail. This removes the duplicate definition in arch/ppc.

2008-04-24[POWERPC] Fix mv64x60 early console code to use cell-index propertyRemi Machet
The MPSC driver and prpmc2800.dts have been modified to use property 'cell-index' as the serial port number, but the early serial console driver for the mv64x60 has not been modified to use this new property. This fixes it. Signed-off-by: Remi Machet (rmachet@slac.stanford.edu) Acked-by: Dale Farnsworth <dale@farnsworth.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
2008-04-24[POWERPC] Initialize all mv64x60 devices even if one failsRemi Machet
If one of the devices of the mv64x60 init fails, the remaining devices are not initialized. This changes the code to display an error and continue the initialization. Signed-off-by: Remi Machet (rmachet@slac.stanford.edu) Signed-off-by: Paul Mackerras <paulus@samba.org>
2008-04-24[POWERPC] Use default values if necessary in mv64x60 I2C initializationRemi Machet
I2C parameters freq_m and freq_n are assigned defaults in the code, but if properties for those parameters are not found in the open firmware description the init routine returns an error and doesn't create the platform device. This changes the code so that it doesn't return an error if the properties are not found but instead uses the default values.
