It still keeps arch-specific files for: * S390-32: it uses a packed structure to pass all the arguments on syscall. It is the only supported port that implements __NR_fadvise64_64 in this way. * ARM: it does not implement __NR_fadvise64 (as other 32-bits ports), so posix_fadvise calls internal posix_fadvise64 symbol. * MIPS64 n64: it requires a different version number that other ports. The new macro SYSCALL_LL{64} is used to handle the offset argument and INTERNAL_SYSCALL_CALL to handle passing the correct number of expect arguments. The default Linux adds two new defines a port can use to control how __NR_fadvise64_64 passes the kernel arguments: * __ASSUME_FADVISE64_64_6ARG: the 'advise' argument is moved on second position. This is the case of powerpc32 and arm to avoid implement 7 argument syscall. * __ASSUME_FADVISE64_64_NO_ALIGN: for ABIs that defines __ASSUME_ALIGNED_REGISTER_PAIRS packs the offset without the leading '0'. This is the case of tile 32 bits. ARM also defines __NR_fadvise64_64 as __NR_arm_fadvise64_64 (which is also handled on arch kernel-feature.h). Tested on x86_64, x32, i686, armhf, and aarch64. * posix/Makefile (tests): Add tst-posix_fadvise and tst-posix_fadvise64. * posix/tst-posix_fadvise.c: New file. * posix/tst-posix_fadvise64.c: Likewise. * posix/tst-posix_fadvise-common.c: Likewise. * sysdeps/unix/sysv/linux/arm/kernel-features.h (__ASSUME_FADVISE64_64_6ARG): Define. * sysdeps/unix/sysv/linux/powerpc/kernel-features.h [!__powerpc64__] (__ASSUME_FADVISE64_64_6ARG): Add define. * sysdeps/unix/sysv/linux/arm/posix_fadvise64.c: Remove file. * sysdeps/unix/sysv/linux/generic/wordsize-32/posix_fadvise.c: Likewise. * sysdeps/unix/sysv/linux/i386/posix_fadvise64.S: Likewise. * sysdeps/unix/sysv/linux/mips/mips32/posix_fadvise.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips32/posix_fadvise64.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n32/posix_fadvise.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n32/posix_fadvise64.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n64/posix_fadvise.c: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/posix_fadvise.c: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/posix_fadvise64.c: Likewise. * sysdeps/unix/sysv/linux/wordsize-64/posix_fadvise.c: Likewise. * sysdeps/unix/sysv/linux/wordsize-64/posix_fadvise64.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n64/posix_fadvise64.c (SHLIB_COMPAT(libc, GLIBC_2_2, GLIBC_2_3_3) [__posix_fadvise64_l64]: Alias to __posix_fadvise64_l32.

(SHLIB_COMPAT(libc, GLIBC_2_2, GLIBC_2_3_3) [__posix_fadvise64_l64]: Add versioned definition to posix_fadvise64. * sysdeps/unix/sysv/linux/posix_fadvise.c (posix_fadvise): Build iff __OFF_T_MATCHES_OFF64_T is defined, use INTERNAL_SYSCALL_CALL, add __ASSUME_FADVISE64_64_6ARG/__ASSUME_FADVISE64_64_NO_ALIGN support. * sysdeps/unix/sysv/linux/posix_fadvise64.c (posix_fadvise64): Add __ASSUME_FADVISE64_64_NO_ALIGN support and use INTERNAL_SYSCALL_CALL.
