because struct stat is no longer assumed to correspond to the structure used by the stat-family syscalls, it's not valid to make any of these syscalls directly using a buffer of type struct stat. commit 94938920 moved all logic around this change for stat-family functions into fstatat.c, making the others wrappers for it. but a few other direct uses of the syscall were overlooked. the ones in tmpnam/tempnam are harmless since the syscalls are just used to test for file existence. however, the uses in fchmodat and __map_file depend on getting accurate file properties, and these functions may actually have been broken one or more mips variants due to removal of conversion hacks from syscall_arch.h. as a low-risk fix, simply use struct kstat in place of struct stat in the affected places.

these did not truncate excess precision in the return value. fixing them looks like considerable work, and the current C code seems to outperform them significantly anyway. long double functions are left in place because they are not subject to excess precision issues and probably better than the C code.

for functions implemented in C, this is a requirement of C11 (F.6); strictly speaking that text does not apply to standard library functions, but it seems to be intended to apply to them, and C2x is expected to make it a requirement. failure to drop excess precision is particularly bad for inverse trig functions, where a value with excess precision can be outside the range of the function (entire range, or range for a particular subdomain), breaking reasonable invariants a caller may expect.

under _GNU_SOURCE for namespace cleanliness, analogous to other archs. the original placement in sys/reg.h seems not to have been motivated; such a header isn't even present on other implementations.

some nontrivial number of applications have historically performed direct syscalls for these operations rather than using the public functions. such usage is invalid now that time_t is 64-bit and these syscalls no longer match the types they are used with, and it was already harmful before (by suppressing use of vdso). since syscall() has no type safety, incorrect usage of these syscalls can't be caught at compile-time. so, without manually inspecting or running additional tools to check sources, the risk of such errors slipping through is high. this patch renames the syscalls on 32-bit archs to clock_gettime32 and gettimeofday_time32, so that applications using the original names will fail to build without being fixed. note that there are a number of other syscalls that may also be unsafe to use directly after the time64 switchover, but (1) these are the main two that seem to be in widespread use, and (2) most of the others continue to have valid usage with a null timeval/timespec argument, as the argument is an optional timeout or similar.

_POSIX_VDISABLE is only visible if unistd.h has already been included, so conditional use of it here makes no sense. the value is always 0 anyway; it does not vary.

This patch adds an explicit cast to the int arguments passed to the inline asm used in the RISC-V's implementation of `a_cas`, to ensure that they are properly sign extended to 64 bits. They aren't automatically sign extended by Clang, and GCC technically also doesn't guarantee that they will be sign extended.

the bug fixed in commit b82cd6c7 was mostly masked on arm because __hwcap was zero at the point of the call from the dynamic linker to __set_thread_area, causing the access to libc.auxv to be skipped and kuser_helper versions of TLS access and atomics to be used instead of the armv6 or v7 versions. however, on kernels with kuser_helper removed for hardening it would crash. since __set_thread_area potentially uses __hwcap, it must be initialized before the function is called. move the AT_HWCAP lookup from stage 3 to stage 2b.

This enables alternative compilers, which may not define __GNUC__, to implement alloca, which is still fairly widely used. This is similar to how stdarg.h already works in musl; compilers must implement __builtin_va_arg, there is no fallback definition.

this change was discussed on the mailing list thread for the linux uapi v5.3 patches, and submitted as a v2 patch, but overlooked when I applied the patches much later. revert commit f291c09e and apply the v2 as submitted; the net change is just padding. notes by Szabolcs Nagy follow: compared to the linux uapi (and glibc) a padding is used instead of aligned attribute for keeping the layout the same across targets, this means the alignment of the struct may be different on some targets (e.g. m68k where uint64_t is 2 byte aligned) but that should not affect syscalls and this way the abi does not depend on nonstandard extensions.

at least gcc 9 broke execution of DT_INIT/DT_FINI for fdpic archs (presently only sh) by recognizing that the stores to the compound-literal function descriptor constructed to call them were dead stores. there's no way to make a "may_alias function", so instead launder the descriptor through an asm-statement barrier. in practice just making the compound literal volatile seemed to have worked too, but this should be less of a hack and more accurately convey the semantics of what transformations are not valid.

commit 1c84c999 moved the call to __init_tp above the initialization of libc.auxv, inadvertently breaking archs where __set_thread_area examines auxv for the sake of determining the TLS/atomic model needed at runtime. this broke armv6 and sh2.
