2020-04-26MIPS: Rename the "Fill" cache ops to avoid build failureHuacai Chen
MIPS define a "Fill" macro as a cache operation in cacheops.h, this will cause build failure under some special configurations because in seq_file.c there is a "Fill" label. To avoid this failure we rename the "Fill" macro to "Fill_I" which has the same coding style as other cache operations in cacheops.h (we think renaming the "Fill" macro is more reasonable than renaming the "Fill" label).

2020-04-21MIPS: Make sparse_init() using top-down allocationTiezhu Yang
In the current code, if CONFIG_SWIOTLB is set, when failed to get IO TLB memory from the low pages by plat_swiotlb_setup(), it may lead to the boot process failed with kernel panic. (1) On the Loongson and SiByte platform arch/mips/loongson64/dma.c arch/mips/sibyte/common/dma.c void __init plat_swiotlb_setup(void) { swiotlb_init(1); } kernel/dma/swiotlb.c void __init swiotlb_init(int verbose) { ... vstart = memblock_alloc_low(PAGE_ALIGN(bytes), PAGE_SIZE); if (vstart && !swiotlb_init_with_tbl(vstart, io_tlb_nslabs, verbose)) return; ... pr_warn("Cannot allocate buffer"); no_iotlb_memory = true; } phys_addr_t swiotlb_tbl_map_single() { ... if (no_iotlb_memory) panic("Can not allocate SWIOTLB buffer earlier ..."); ... } (2) On the Cavium OCTEON platform arch/mips/cavium-octeon/dma-octeon.c void __init plat_swiotlb_setup(void) { ... octeon_swiotlb = memblock_alloc_low(swiotlbsize, PAGE_SIZE); if (!octeon_swiotlb) panic("%s: Failed to allocate %zu bytes align=%lx\n", __func__, swiotlbsize, PAGE_SIZE); ... } Because IO_TLB_DEFAULT_SIZE is 64M, if the rest size of low memory is less than 64M when call plat_swiotlb_setup(), we can easily reproduce the panic case. In order to reduce the possibility of kernel panic when failed to get IO TLB memory under CONFIG_SWIOTLB, it is better to allocate low memory as small as possible before plat_swiotlb_setup(), so make sparse_init() using top-down allocation.

Commit 31168f033e37 ("mips: drop __pXd_offset() macros that duplicate pXd_index() ones") is correct that pud_index() & __pud_offset() are the same when pud_index() is actually provided, however it does not take into account the __PAGETABLE_PUD_FOLDED case. This has broken MIPS KVM compilation because it relied on availability of pud_index(). Define pud_index() regardless of page table folded. It will evaluate to actual index for 4-level pagetables and to 0 for folded PUD level.
