iirc this is the core of the issue: The L1 Section descriptors access
permissions are still the old ones, not the v7 versions.
arm/include/pmap.h:
#define L1_S_PROT_U (L1_S_AP(AP_U))
#define L1_S_PROT_W (L1_S_AP(AP_W))
#define L1_S_PROT_MASK (L1_S_PROT_U|L1_S_PROT_W)
#define L1_S_PROT(ku, pr) ((((ku) == PTE_USER) ? L1_S_PROT_U : 0) | \
(((pr) & VM_PROT_WRITE) ? L1_S_PROT_W : 0))
arm/include/pte.h:
#define L1_S_AP(x) ((x) << 10) /* access permissions */
#define L1_S_V7_AP(x) ((((x) & 0x4) << 13) | (((x) & 3) << 10)) /* AP */
