2008-12-18[ARM] S3C24A0: Remove duplicate <mach/io.h> fileBen Dooks
The commit 39263db7986bf15c753f6847699107bdf5a2e318 added a default <mach/io.h> implementation which is shared if needed between all the s3c implementations. Remove the s3c24a0 version which is the same as this. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2008-12-18[ARM] S3C64XX: Remove __virt_to_bus/__bus_to_virt macrosBen Dooks
The changes for ARM highmem support have removed the need for the __virt_to_bus and __bus_to_virt macros, so remove them from this build. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2008-12-18[ARM] S3C24XX: Add fourth UART definition for S3C2443Ben Dooks
Add the fourth UART definition for the S3C2443, and at the same time fixup the problems caused by the enlarging of the UART array in the previous commits. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2008-12-18[ARM] S3C: Update CONFIG_SERIAL_SAMSUNG_UARTS handlingBen Dooks
Fix the usage of CONFIG_SERIAL_SAMSUNG_UARTS in several places in the kernel where it had been missed. This finishes fixing a long standing issue where S3C2443 and S3C64XX could not use the 4th UART Signed-off-by: Ben Dooks <ben-linux@fluff.org>

2008-12-18x86: use possible_cpus=NUM to extend the possible cpus allowedMike Travis
Impact: add new boot parameter Use possible_cpus=NUM kernel parameter to extend the number of possible cpus. The ability to HOTPLUG ON cpus that are "possible" but not "present" is dealt with in a later patch. Signed-off-by: Mike Travis <travis@sgi.com>
2008-12-18x86: fix cpu_mask_to_apicid_and to include cpu_online_maskMike Travis
Impact: fix potential APIC crash In determining the destination apicid, there are usually three cpumasks that are considered: the incoming cpumask arg, cfg->domain and the cpu_online_mask. Since we are just introducing the cpu_mask_to_apicid_and function, make sure it includes the cpu_online_mask in it's evaluation. [Added with this patch.] There are two io_apic.c functions that did not previously use the cpu_online_mask: setup_IO_APIC_irq and msi_compose_msg. Both of these simply used cpu_mask_to_apicid(cfg->domain & TARGET_CPUS), and all but one arch (NUMAQ[*]) returns only online cpus in the TARGET_CPUS mask, so the behavior is identical for all cases. [*: NUMAQ bug?] Note that alloc_cpumask_var is only used for the 32-bit cases where it's highly likely that the cpumask set size will be small and therefore CPUMASK_OFFSTACK=n. But if that's not the case, failing the allocate will cause the same return value as the default. Signed-off-by: Mike Travis <travis@sgi.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-12-18Merge branch 'x86/apic' into cpus4096Ingo Molnar
This done for conflict prevention: we merge it into the cpus4096 tree because upcoming cpumask changes will touch apic.c that would collide with x86/apic otherwise.
