2 * We need constants.h for:
7 #include <asm/asm-offsets.h>
8 #include <asm/thread_info.h>
11 * vma_vm_mm - get mm pointer from vma pointer (vma->vm_mm)
13 .macro vma_vm_mm, rd, rn
14 ldr \rd, [\rn, #VMA_VM_MM]
18 * vma_vm_flags - get vma->vm_flags
20 .macro vma_vm_flags, rd, rn
21 ldr \rd, [\rn, #VMA_VM_FLAGS]
25 ldr \rd, [\rn, #TI_TASK]
26 ldr \rd, [\rd, #TSK_ACTIVE_MM]
30 * act_mm - get current->active_mm
35 ldr \rd, [\rd, #TI_TASK]
36 ldr \rd, [\rd, #TSK_ACTIVE_MM]
40 * mmid - get context id from mm pointer (mm->context.id)
43 ldr \rd, [\rn, #MM_CONTEXT_ID]
47 * mask_asid - mask the ASID from the context ID
53 .macro crval, clear, mmuset, ucset
64 * cache_line_size - get the cache line size from the CSIDR register
65 * (available on ARMv7+). It assumes that the CSSR register was configured
66 * to access the L1 data cache CSIDR.
68 .macro dcache_line_size, reg, tmp
69 mrc p15, 1, \tmp, c0, c0, 0 @ read CSIDR
70 and \tmp, \tmp, #7 @ cache line size encoding
71 mov \reg, #16 @ size offset
72 mov \reg, \reg, lsl \tmp @ actual cache line size
