Subject: [ARM] 4388/1: no need for arm/mm mmap range checks for non-mmu
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=95ba71f76f1cce550cb2e2b345a204d4a926d29c;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

[ARM] 4388/1: no need for arm/mm mmap range checks for non-mmu

We don't need valid_phys_addr_range() or valid_mmap_phys_addr_range()
for the !CONFIG_MMU case.
