* bcm47xx: add support for bcma busHauke Mehrtens2011-08-088-2/+179
| | | | | | | | | | This patch add support for the bcma bus. Broadcom uses only Mips 74K CPUs on the new SoC and on the old ons using ssb bus there are no Mips 74K CPUs.

* bcm47xx: prepare to support different busesHauke Mehrtens2011-08-088-59/+150
| | | | | | | | | | | | Prepare bcm47xx to support different System buses. Before adding support for bcma it should be possible to build bcm47xx without the need of ssb. With this patch bcm47xx does not directly contain a ssb_bus, but a union contain all the supported system buses. As a SoC just uses one system bus a union is a good choice.

* atomic: cleanup asm-generic atomic*.h inclusionArun Sharma2011-07-271-6/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | After changing all consumers of atomics to include <linux/atomic.h>, we ran into some compile time errors due to this dependency chain: linux/atomic.h -> asm/atomic.h -> asm-generic/atomic-long.h where atomic-long.h could use funcs defined later in linux/atomic.h without a prototype. This patches moves the code that includes asm-generic/atomic*.h to linux/atomic.h. Archs that need <asm-generic/atomic64.h> need to select CONFIG_GENERIC_ATOMIC64 from now on (some of them used to include it unconditionally). Compile tested on i386 and x86_64 with allnoconfig.

| * MIPS: Close races in TLB modify handlers.David Daney2011-07-261-98/+194
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Page table entries are made invalid by writing a zero into the the PTE slot in a page table. This creates a race condition with the TLB modify handlers when they are updating the PTE. CPU0 CPU1 Test for _PAGE_PRESENT . set to not _PAGE_PRESENT (zero) Set to _PAGE_VALID So now the page not present value (zero) is suddenly valid and user space programs have access to physical page zero. We close the race by putting the test for _PAGE_PRESENT and setting of _PAGE_VALID into an atomic LL/SC section. This requires more registers than just K0 and K1 in the handlers, so we need to save some registers to a save area and then restore them when we are done. The save area is an array of cacheline aligned structures that should not suffer cache line bouncing as they are CPU private.

| * MIPS: Enable cpu_has_clo_clz for MIPS Technologies' platformsShinya Kuribayashi2011-07-252-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Enable cpu_has_clo_clz only when CONFIG_CPU_MIPS32 or CONFIG_CPU_MIPS64 is selected. This will optimize fls() and __fls() to use CLZ insn, and eventually ffs() and __ffs() as well. Malta and MIPSSim are development platforms, and need to take care of various processor configurations, release rivisions and so on, even across different MIPS ISAs. For such platforms we have to be careful, for instance, with turning on cpu_has_mips{32,64}r[12] features. As for CLZ, all MIPS32/64 processors support it, regardless of release revisions.

| * 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.

On such a configuration, max_low_pfn should be used to set max_mapnr. This was seen on 2.6.34.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

There are many more instances of more complicated macros having unnecessary trailing semicolons, but this pile seems to be all of the cases of simple values suffering from the problem.

Now that we start using virtio for inter-processor communications, we need to source the virtio Kconfig outside of the virtualization scope too. Moreover, some architectures might use virtio for both virtualization and inter-processor communications, so directly sourcing virtio might yield unexpected results due to conflicting selections. The simple solution offered by this patch is to always source virtio's Kconfig in drivers/Kconfig, and remove it from the appropriate arch Kconfigs. Additionally, a virtio menu entry has been added so virtio drivers don't show up in the general drivers menu. This way anyone can use virtio, though it's arguably less accessible (and neat!) for virtualization users now. Note: some architectures (mips and sh) seem to have a VIRTUALIZATION menu merely for sourcing virtio's Kconfig, so that menu is removed too.
