* MIPS: Limit fixrange_init() to the FIXMAP regionKevin Cernekee2011-07-253-5/+5
| | | | | | | | | | | | | fixrange_init() allocates page tables for all addresses higher than FIXADDR_TOP. On processors that override the default FIXADDR_TOP address of 0xfffe_0000, this can consume up to 4 pages (1 page per 4MB) for pgd's that are never used.

* MIPS: Move FIXADDR_TOP into spaces.hKevin Cernekee2011-07-255-9/+56
| | | | | | | | | | | | | | | Memory maps and addressing quirks are normally defined in <spaces.h>. There are already three targets that need to override FIXADDR_TOP, and others exist. This will be a cleaner approach than adding lots of ifdefs in fixmap.h .

* MIPS: Add SYNC after cacheflushKevin Cernekee2011-07-251-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On processors with deep write buffers, it is likely that many cycles will pass between a CACHE instruction and the time the data actually gets written out to DRAM. Add a SYNC instruction to ensure that the buffers get emptied before the flush functions return. Actual problem seen in the wild: 1) dma_alloc_coherent() allocates cached memory 2) memset() is called to clear the new pages 3) dma_cache_wback_inv() is called to flush the zero data out to memory 4) dma_alloc_coherent() returns an uncached (kseg1) pointer to the freshly allocated pages 5) Caller writes data through the kseg1 pointer 6) Buffered writeback data finally gets flushed out to DRAM 7) Part of caller's data is inexplicably zeroed out This patch adds SYNC between steps 3 and 4, which fixed the problem.

* MIPS: pfn_valid() is broken on low memory HIGHMEM systemsKevin Cernekee2011-07-251-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pfn_valid() compares the PFN to max_mapnr: __pfn >= min_low_pfn && __pfn < max_mapnr; On HIGHMEM kernels, highend_pfn is used to set the value of max_mapnr. Unfortunately, highend_pfn is left at zero if the system does not actually have enough RAM to reach into the HIGHMEM range. This causes pfn_valid() to always return false, and when debug checks are enabled the kernel will fail catastrophically: Memory: 22432k/32768k available (2249k kernel code, 10336k reserved, 653k data, 1352k init, 0k highmem) NR_IRQS:128 kfree_debugcheck: out of range ptr 81c02900h. Kernel bug detected[#1]: Cpu 0 $ 0 : 00000000 10008400 00000034 00000000 $ 4 : 8003e160 802a0000 8003e160 00000000 $ 8 : 00000000 0000003e 00000747 00000747 ... On such a configuration, max_low_pfn should be used to set max_mapnr. This was seen on 2.6.34.

* MIPS: topdown mmap supportJian Peng2011-07-252-23/+171
| | | | | | | | | | | | | | | | | | | | This patch introduced topdown mmap support in user process address space allocation policy. Recently, we ran some large applications that use mmap heavily and lead to OOM due to inflexible mmap allocation policy on MIPS32. Since most other major archs supported it for years, it is reasonable to follow the trend and reduce the pain of porting applications. Due to cache aliasing concern, arch_get_unmapped_area_topdown() and other helper functions are implemented in arch/mips/kernel/syscall.c.

This means that the variable gcmp_present well be left at its default value of -1 which normally is meant to indicate that GCMP has not yet been mmapped. This non-zero value is now interpreted as GCMP being present resulting in a write attempt to a GCMP register resulting in a crash.

The gpio irq handler falsely assumes that the handler data is the irq base number and that is no longer true. Set the irq handler data to be a pointer to the corresponding gpio controller. The chained irq handler can then use it to extract both the irq base number and the gpio registers structure.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The PXA platform code has a static inline helper called gpio_to_chip which clashes with the gpiolib namespace if we try to expose the function with the same name from gpiolib, and it's still confusing even if we don't do that. So rename it to gpio_to_pxachip().

| * | | genirq: replace irq_gc_ack() with {set,clr}_bit variants (fwd)Simon Guinot2011-07-074-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a regression introduced by e59347a "arm: orion: Use generic irq chip". Depending on the device, interrupts acknowledgement is done by setting or by clearing a dedicated register. Replace irq_gc_ack() with some {set,clr}_bit variants allows to handle both cases. Note that this patch affects the following SoCs: Davinci, Samsung and Orion. Except for this last, the change is minor: irq_gc_ack() is just renamed into irq_gc_ack_set_bit(). For the Orion SoCs, the edge GPIO interrupts support is currently broken. irq_gc_ack() try to acknowledge a such interrupt by setting the corresponding cause register bit. The Orion GPIO device expect the opposite. To fix this issue, the irq_gc_ack_clr_bit() variant is used. Tested on Network Space v2.

The 6th bit of the NFC APMU register indicates NFC works whether at 156Mhz or 78Mhz. So 0x19b indicates NFC works at 156Mhz, and 0x1db indicates it works at 78Mhz.
