linux-user: Add translation for argument of msync()

2023-03-10T19:45:47Z

msync() uses the flags MS_ASYNC, MS_INVALIDATE and MS_SYNC, which differ between platforms, specifcally on alpha and hppa. Add a target to host translation for those and wire up a nicer strace output. This fixes the testsuite of the macaulay2 debian package with a hppa-linux guest on a x86-64 host.

linux-user: Fix unaligned memory access in prlimit64 syscall

2023-03-10T19:42:00Z

target_rlimit64 contains uint64_t fields, so it's 8-byte aligned on some hosts, while some guests may align their respective type on a 4-byte boundary. This may lead to an unaligned access, which is an UB. Fix by defining the fields as abi_ullong. This makes the host alignment match that of the guest, and lets the compiler know that it should emit code that can deal with the guest alignment. While at it, also use __get_user() and __put_user() instead of tswap64().

linux-user: move target_flat.h to target subdirs

2023-02-03T21:55:12Z

This makes target_flat.h behave like every other target_xxx.h header. It also makes it actually work -- while the current header says adding a header to the target subdir overrides the common one, it doesn't. This is for two reasons: * meson.build adds -Ilinux-user before -Ilinux-user/$arch * the compiler search path for "target_flat.h" looks in the same dir as the source file before searching -I paths. This can be seen with the xtensa port -- the subdir settings aren't used which breaks stack setup. Move it to the generic/ subdir and add include stubs like every other target_xxx.h header is handled.

linux-user: Provide MADV_* definitions

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.
