From: Will Deacon Date: Mon, 2 Jun 2014 10:47:29 +0000 (+0100) Subject: arm64: uid16: fix __kernel_old_{gid,uid}_t definitions X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=34c65c43f1518bf85f93526ad373adc6a683b4c5;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git arm64: uid16: fix __kernel_old_{gid,uid}_t definitions Whilst native arm64 applications don't have the 16-bit UID/GID syscalls wired up, compat tasks can still access them. The 16-bit wrappers for these syscalls use __kernel_old_uid_t and __kernel_old_gid_t, which must be 16-bit data types to maintain compatibility with the 16-bit UIDs used by compat applications. This patch defines 16-bit __kernel_old_{gid,uid}_t types for arm64 instead of using the 32-bit types provided by asm-generic.
