Commit 1b028f784e8c introduced two mmap() bases for 32-bit syscalls and for 64-bit syscalls. The mmap() code in x86 was modified to handle the separation, but the patch series missed to update the hugetlb code.
As a consequence a 32bit application mapping a file on hugetlbfs uses the 64-bit mmap base for address space allocation, which fails.
Adjust the hugetlb mapping code to use the proper bases depending on the syscall invocation mode (64-bit or compat).
[ tglx: Massaged changelog and switched from asm/compat.h to linux/compat.h ]
