2009-12-06ARM: 5814/1: SA1100: h3100/h3600: convert all users of assign_h3600_egpio to ↵Dmitry Artamonow
gpiolib Use of gpio_request/gpio_free in some callbacks may look ugly, but corresponding drivers (sa1100_serial and sa1100_fb) don't provide (yet) init/exit hooks and registering these gpios in *_mach_init is also not possible, because htc-gpio driver starts a bit later...

2009-12-06ARM: 5812/1: SA1100: h3100/h3600: separate machine-specific LCD helpersDmitry Artamonow
h3100 and h3600 have different sets of LCD-controlling gpios, which mapped to the same "abstracted" EGPIO. As we plan to get rid of those abstracted egpios completely, we need to separate these helper functions.

2009-12-05IXP4xx: Extend PCI MMIO indirect address space to 1 GB.Krzysztof Hałasa
IXP4xx CPUs can indirectly access the whole 4 GB PCI MMIO address space (using the non-prefetch registers). Previously the available space depended on the CPU variant, since one of the IXP43x platforms needed more than the usual 128 MB. 1 GB should be enough for everyone, and if not, we can trivially increase it.

2009-12-05IXP4xx: change the timer base frequency to 66.666000 MHz.Krzysztof Hałasa
Clock generators used by IXP4xx processors are usually 33.333 MHz, sometimes 33.33 MHz and few platforms use 33 MHz. The timers tick twice as fast, that means 66.666, 66.66 or 66 MHz. Current 66.666666 MHz means 10 ppm offset from the usual 66.666 MHz. Signed-off-by: Krzysztof Hałasa <khc@pm.waw.pl>

2009-12-04ARM: I-cache: flush executable mappings in flush_cache_range()Russell King
Dirk Behme reported instability on ARM11 SMP (VIPT non-aliasing cache) caused by the dynamic linker changing protection on text pages to write GOT entries. The problem is due to an interaction between the write faulting code providing new anonymous pages which are incoherent with the I-cache due to write buffering, and the I-cache not having been invalidated. a4db94d plugs the hole with the data cache coherency. This patch provides the other half of the fix by flushing the I-cache in flush_cache_range() for VM_EXEC VMAs (which is what we have when the region is being made executable again.) This ensures that the I-cache will be up to date with the newly COW'd pages. Note: if users are writing instructions, then they still need to use the ARM sys_cacheflush API to ensure that the caches are correctly synchronized.

2009-12-04ARM: I-cache: avoid flushing in flush_cache_mm()Russell King
flush_cache_mm() is called in two cases: 1. when a process exits, just before the page tables are torn down. We can allow the stale lines to evict themselves over time without causing any harm. 2. when a process forks, and we've allocated a new ASID. The instruction cache issues are dealt with as pages are brought into the new process address space. Flushing the I-cache here is therefore unnecessary. However, we must keep the VIPT aliasing D-cache flush to ensure that any dirty cache lines are not written back after the pages have been reallocated for some other use - which would result in corruption.

2009-12-04ARM: 5794/1: Flush the D-cache during copy_user_highpage()Catalin Marinas
The I and D caches for copy-on-write pages on processors with write-allocate caches become incoherent causing problems on application relying on CoW for text pages (dynamic linker relocating symbols in a text page). This patch flushes the D-cache for such pages. Cc: Nicolas Pitre <nico@fluxnic.net> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2009-12-04ARM: Remove __flush_icache_all() from __flush_dcache_page()Russell King
Both call sites for __flush_dcache_page() end up calling __flush_icache_all() themselves, so having __flush_dcache_page() do this as well is wasteful. Remove the duplicated icache flushing. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
