Experimental fork of QEMU with video encoding patches https://git.openslx.org/bwlp/qemu.git/atom/linux-user/aarch64?h=spice_video_codecs 2022-09-27T07:30:09+00:00 2022-09-27T07:30:09+00:00 Ilya Leoshkevich 2022-09-06T00:08:35+00:00 urn:sha1:9f22020b91ae235be2b27c47d11e842872ec5e85 Provide MADV_* definitions using target_mman.h header, similar to what kernel does. Most architectures use the same values, with the exception of alpha and hppa.

This more closely mirrors the code structure in the kernel, and is slightly clearer. Reject rather than silently skip incorrect VL and SVE record sizes, bringing our checks in to line with those the kernel does.

We were silently allowing these cases to pass, dropping the record.
