As a result, passing a negative length accidentally succeeds in truncating to file size between 2GiB and 4GiB. Changing the type of the compat syscall to the signed compat_off_t changes the behavior so it instead returns -EINVAL. The native entry point, the truncate() syscall and the corresponding loff_t based variants are all correct already and do not suffer from this mistake.

This was addressed on parisc by switching to compat_sys_io_pgetevents_time64() in commit 6431e92fc827 ("parisc: io_pgetevents_time64() needs compat syscall in 32-bit compat mode"), as well as by using more sophisticated system call wrappers on x86 and s390. However, arm64, mips, powerpc, sparc and riscv still have the same bug. Changes all of them over to use compat_sys_io_pgetevents_time64() like parisc already does. This was clearly the intention when the function was originally added, but it got hooked up incorrectly in the tables.

During the conversion to the modern syscall.tbl format, the older one of the two broke in compat mode, and now refers to the native 64-bit syscall. Restore the correct behavior. This has very little effect, as glibc has been using the newer number anyway.

The direct syscalls just need to use the compat version. For socketcall, the same thing could be done, but it seems better to completely remove the custom assembler code for it and just use the same implementation that everyone else has.

As far as I can tell, the problem is that the function arguments on parisc are sorted backwards (26, 25, 24, 23, ...) compared to everyone else, so the calling conventions of using an even/odd register pair in native word order result in the lower word coming first in function arguments, matching the expected behavior on little-endian architectures. The system call conventions however ended up matching what the other 32-bit architectures do. A glibc cleanup in 2020 changed the userspace behavior in a way that handles all architectures consistently, but this inadvertently broke parisc32 by changing to the same method as everyone else. The change made it into glibc-2.35 and subsequently into debian 12 (bookworm), which is the latest stable release. This means we need to choose between reverting the glibc change or changing the kernel to match it again, but either hange will leave some systems broken. Pick the option that is more likely to help current and future users and change the kernel to match current glibc. This also means the behavior is now consistent across architectures, but it breaks running new kernels with old glibc builds before 2.35.

In userspace, I found that musl, glibc, uclibc and strace all expect the normal calling conventions with 'nbytes' last, so changing the kernel to match them should make all of those work. In order to be able to also fix libc implementations to work with existing kernels, they need to be able to tell which ABI is used. An easy way to do this is to add yet another system call using the sync_file_range2 ABI that works the same on all architectures. Old user binaries can now work on new kernels, and new binaries can try the new sync_file_range2() to work with new kernels or fall back to the old sync_file_range() version if that doesn't exist.

The system call is therefore incompatible with all existing binaries. While it would be possible to implement support for seven arguments like on mips, it seems better to use a six-argument version, either with the normal argument order but misaligned as on most architectures or with the reordered sync_file_range2() calling conventions as on arm and powerpc.

Make this consistent by using an unsigned argument everywhere. This changes the behavior slightly, as the argument is shifted to a page number, and an user input with the top bit set would result in a negative page offset rather than a large one as we use elsewhere. For riscv, the 32-bit sys_mmap2() definition actually used a custom type that is different from the global declaration, but this was missed due to an incorrect type check.

Address this by adding another level of indirection, checking for both the target ABI (32 or 64) and the __ARCH_WANT_TIME32_SYSCALLS macro. The macro arguments are meant to follow the syscall.tbl format, the idea here is that by the end of the series, all other syscalls are changed to the same format to make it possible to move all architectures over to generating the system call table consistently. Only this patch needs to be backported though.
