3.16.81-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: Yury Norov <ynorov@xxxxxxxxxxxxxxxxxx> commit b9b7aebb42d1b1392f3111de61136bb6cf3aae3f upstream. ARM glibc uses (4 * __getpagesize()) for SHMLBA, which is correct for 4KB pages and works fine for 64KB pages, but the kernel uses a hardcoded 16KB that is too small for 64KB page based kernels. This changes the definition to what user space sees when using 64KB pages.
