2011-07-25um: reinstate kernel version in generated .configGeert Uytterhoeven1-0/+2
Commit 0954828fcbf3 ("kconfig: replace KERNELVERSION usage by the mainmenu's prompt") made the kernel version disappear from the generated .config file when configuring for UML. As UML's Kconfig doesn't have a mainmenu, kconfig falls back to the default string "Linux Kernel Configuration". Add a suitable mainmenu to the main UML Kconfig file to fix this.

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.

2011-07-25MIPS: Add SYNC after cacheflushKevin Cernekee1-0/+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.

2011-07-25MIPS: pfn_valid() is broken on low memory HIGHMEM systemsKevin Cernekee1-1/+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.

2011-07-25MIPS: topdown mmap supportJian Peng2-23/+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.
