* ARM: add generic ioremap optimization by reusing static mappingsNicolas Pitre2011-11-273-25/+64
| | | | | | | | | | | | Now that we have all the static mappings from iotable_init() located in the vmalloc area, it is trivial to optimize ioremap by reusing those static mappings when the requested physical area fits in one of them, and so in a generic way for all platforms.

* ARM: simplify __iounmap() when dealing with section based mappingNicolas Pitre2011-11-271-11/+9
| | | | | | | | | | | | | | Firstly, there is no need to have a double pointer here as we're only walking the vmlist and not modifying it. Secondly, for the same reason, we don't need a write lock but only a read lock here, since the lock only protects the coherency of the list nothing else. Lastly, the reason for holding a lock is not what the comment says, so let's remove that misleading piece of information. Signed-off-by: Nicolas Pitre <nicolas.pitre@linaro.org>
* ARM: move iotable mappings within the vmalloc regionNicolas Pitre2011-11-273-27/+41
| | | | | | | | | | | | | | | | | | | In order to remove the build time variation between different SOCs with regards to VMALLOC_END, the iotable mappings are now allocated inside the vmalloc region. This allows for VMALLOC_END to be identical across all machines. The value for VMALLOC_END is now set to 0xff000000 which is right where the consistent DMA area starts. To accommodate all static mappings on machines with possible highmem usage, the default vmalloc area size is changed to 240 MB so that VMALLOC_START is no higher than 0xf0000000 by default.

* mm: add vm_area_add_early()Nicolas Pitre2011-11-182-2/+28
| | | | | | | | | | | | | | | | | | | | The existing vm_area_register_early() allows for early vmalloc space allocation. However upcoming cleanups in the ARM architecture require that some fixed locations in the vmalloc area be reserved also very early. The name "vm_area_register_early" would have been a good name for the reservation part without the allocation. Since it is already in use with different semantics, let's create vm_area_add_early() instead. Both vm_area_register_early() and vm_area_add_early() can be used together meaning that the former is now implemented using the later where it is ensured that no conflicting areas are added, but no attempt is made to make the allocation scheme in vm_area_register_early() more sophisticated. After all, you must know what you're doing when using those functions.

* ARM: move initialization of the high_memory variable earlierNicolas Pitre2011-11-183-2/+3
| | | | | | | | | | | Some upcoming changes must know the VMALLOC_START value, which is based on high_memory, before bootmem_init() is called. The best location to set it is in sanity_check_meminfo() where the needed computation is already done, and in the non MMU case it is trivial to do now that the meminfo array is already sorted at that point.

* ARM: sort the meminfo array earlierNicolas Pitre2011-11-182-30/+16
| | | | | | | | | | | | | The meminfo array has to be sorted before sanity_check_meminfo() in arch/arm/mm/mmu.c is called for it to work properly. This also allows for a simpler find_limits() in arch/arm/mm/init.c. The sort is moved to arch/arm/kernel/setup.c because that's where the meminfo array is populated. Eventually this should be improved upon to make the memory bank parser a bit more robust against problems such as overlapping memory ranges. Signed-off-by: Nicolas Pitre <nicolas.pitre@linaro.org>
