Mark Rutland 9cc3d0c691 arm64: vdso: don't free unallocated pages ... The aarch32_vdso_pages[] array never has entries allocated in the C_VVAR or C_VDSO slots, and as the array is zero initialized these contain NULL. However in __aarch32_alloc_vdso_pages() when aarch32_alloc_kuser_vdso_page() fails we attempt to free the page whose struct page is at NULL, which is obviously nonsensical. This patch removes the erroneous page freeing.
