vdso: Switch get/put_unaligned() from packed struct to memcpy()

2026-01-14T07:56:41Z

Type punning is necessary for get/put_unaligned() but the use of a packed struct violates strict aliasing rules, requiring -fno-strict-aliasing to be passed to the C compiler. Switch to using memcpy() so that -fno-strict-aliasing isn't necessary.

vdso: Add prototype for __vdso_clock_getres_time64()

2026-01-13T13:42:23Z

For consistency with __vdso_clock_gettime64() there should also be a 64-bit variant of clock_getres(). This will allow the extension of CONFIG_COMPAT_32BIT_TIME to the vDSO and finally the removal of 32-bit time types from the kernel and UAPI. The generic vDSO library already provides nearly all necessary building blocks for architectures to provide this function. Only a prototype is missing. Add the prototype to the generic header so architectures can start providing this function.

vdso: Add struct __kernel_old_timeval forward declaration to gettime.h

2025-09-05T21:04:35Z

The prototype of __vdso_gettimeofday() uses this struct. However gettime.h's own includes do not provide a definition for it. Add a forward declaration, similar to other used structs.

vdso: Move ENABLE_COMPAT_VDSO from core to arm64

2025-09-04T09:23:49Z

The ENABLE_COMAPT_VDSO symbol is only used by arm64 and only for the time-related functionality. There should be no new users, so it doesn't need to be in the generic vDSO code. Move the logic into arm64 architecture-specific code and replace the explicit define by the standard '#ifdef __aarch64__'.
