2006-09-25[ARM] 3830/1: iop3xx: board support file cleanupLennert Buytenhek
Revamp the iop3xx board support: move the support code for each iop board type into its own file, start using platform serial and platform physmap flash devices, switch to a per-board time tick rate, and get rid of the ARCH_EP80219 and STEPD config options by doing the relevant checks at run time.

2006-09-25[ARM] 3825/1: iop3xx: use cp6 enable/disable macrosLennert Buytenhek
Add CP6 enable/disable sequences to the timekeeping code and the IRQ code. As a result, we can't depend on CP6 access being enabled when we enter get_irqnr_and_base anymore, so switch the latter over to using memory-mapped accesses for now.

2006-09-25[ARM] 3824/1: iop3xx: add cp6 enable/disable macrosLennert Buytenhek
Add macros to enable and disable access to CP6. On the iop3xx, enabling CP6 access unfortunately also enables access to that coprocessor from unprivileged code, so we need these macros to enable and disable access to the coprocessor whenever we need to access it.

2006-09-25[ARM] 3814/1: move 80200 dma_inv_range() erratum check out of lineLennert Buytenhek
On stepping A0/A1 of the 80200, invalidating D-cache by line doesn't clear the dirty bits, which means that if we invalidate a dirty line, the dirty data can still be written back to memory later on. To work around this, dma_inv_range() on these two processors is implemented as dma_flush_range() (i.e. do a clean D-cache line before doing the invalidate D-cache line.) For this, we currently have a processor ID check in xscale_dma_inv_range(), but a better solution is to add a separate cache_fns and proc_info for A0/A1 80200.

2006-09-25[ARM] 3813/1: prevent >= 4G /dev/mem mmap()Lennert Buytenhek
Prevent userland from mapping in physical address regions >= 4G by checking for that in valid_mmap_phys_addr_range(). Unfortunately, we cannot override valid_mmap_phys_addr_range() without also overriding valid_phys_addr_range(), so copy drivers/char/mem.c's version of valid_phys_addr_range() over to arch/arm/mm/mmap.c as well.

2006-09-25[ARM] 3810/1: switch atomic helpers over to raw_local_irq_{save,restore}Lennert Buytenhek
Now that we have raw_* variants of local_irq_$FOO(), switch the atomic helpers over to use those raw_* variants. This is necessary when using lockdep on pre-ARMv6 hardware, as lockdep uses atomic_t counters in the trace_hardirqs_off() path.

Change to using flush_cache_all() in pm.c and also remove the need to flush the cache in the PM code. This changes the sleep.S code to have an entry to store the registers for resume, and then a second entry (after the caches are cleaned) to do the suspend and resume.

2006-09-20[ARM] 3759/2: Remove uses of %?Daniel Jacobowitz
Patch from Daniel Jacobowitz The ARM kernel has several uses of asm("foo%?"). %? is a GCC internal modifier used to output conditional execution predicates. However, no version of GCC supports conditionalizing asm statements. GCC 4.2 will correctly expand %? to the empty string in user asms. Earlier versions may reuse the condition from the previous instruction. In 'if (foo) asm ("bar%?");' this is somewhat likely to be right... but not reliable. So, the only safe thing to do is to remove the uses of %?. I believe the tlbflush.h occurances were supposed to be removed before, based on the comment about %? not working at the top of that file. Old versions of GCC could omit branches around user asms if the asm didn't mark the condition codes as clobbered. This problem hasn't been seen on any recent (3.x or 4.x) GCC, but it could theoretically happen. So, where %? was removed a cc clobber was added.

2006-09-20[ARM] Fix kernel/fork.c for lockdep on ARMRussell King
ARM has interrupts enabled over context switches (iow, has __ARCH_WANT_INTERRUPTS_ON_CTXSW defined.) The lockdep code in fork.c assumes that interrupts are always disabled. Fix this wrong assumption by making the initialisation of 'p->hardirqs_enabled' depend on __ARCH_WANT_INTERRUPTS_ON_CTXSW.

2006-09-19Revert mmiocfg heuristics and blacklist changesLinus Torvalds
This reverts commits 11012d419cfc0e0f78ca356aca03674217910124 and 40dd2d20f220eda1cd0da8ea3f0f9db8971ba237, which allowed us to use the MMIO accesses for PCI config cycles even without the area being marked reserved in the e820 memory tables. Those changes were needed for EFI-environment Intel macs, but broke some newer Intel 965 boards, so for now it's better to revert to our old 2.6.17 behaviour and at least avoid introducing any new breakage. Andi Kleen has a set of patches that work with both EFI and the broken Intel 965 boards, which will be applied once they get wider testing.
