syscalls: add generic scripts/syscall.tbl The asm-generic/unistd.h header still follows the old style of defining system call numbers and the table. Most architectures got the new syscall.tbl format as part of the y2038 conversion back in 2018, but the newer architectures that share a single table never did. I did a semi-automated conversion of the asm-generic/unistd.h contents into a syscall.tbl format, using the ABI field to take care of all the relevant differences that are encoded using #ifdef checks in the existing header. Conversion of the architectures is done one at a time in order to be able to review or revert them as needed. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

syscalls: add back legacy __NR_nfsservctl macro The conversion from the old unistd.h file to syscall.tbl dropped the nfsservctl macro. This one was handled inconsistently across architectures in the original introduction of the syscall.tbl format, and I went the other way on this. The syscall was already gone in linux-3.1 before the current users of the generic table (other than openrisc) first appeared, so nobody could actally use it, but putting the number back helps for consistency since there are build scripts that check the presence of all these macros.

syscalls: fix syscall macros for newfstat/newfstatat The __NR_newfstat and __NR_newfstatat macros accidentally got renamed in the conversion to the syscall.tbl format, dropping the 'new' portion of the name. In an unrelated change, the two syscalls are no longer architecture specific but are once more defined on all 64-bit architectures, so the 'newstat' ABI keyword can be dropped from the table as a simplification.

syscalls: fix fstat() entry again The previous patch to fix the newfstatat() syscall entry ended up breaking fstat() instead. Unfortunately these two are not handled the same way, so I messed this one up the exact opposite way.

arc: convert to generic syscall table The uapi/asm/unistd_32.h and asm/syscall_table_32.h headers can now be generated from scripts/syscall.tbl, which makes this consistent with the other architectures that have their own syscall.tbl. arc has a couple of architecture specific system calls, which I add to the generic table. This for some reason includes the deprecated sys_sysfs() syscall that was presumably added by accident. The time32, renameat, stat64 and rlimit entries in the syscall_abis_32 entry are for system calls that were part of the generic ABI when arch/arc got added but are no longer enabled by default for new architectures. Both the user visible side of asm/unistd.h and the internal syscall table in the kernel should have the same effective contents after this. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

csky: convert to generic syscall table The uapi/asm/unistd_32.h and asm/syscall_table_32.h headers can now be generated from scripts/syscall.tbl, which makes this consistent with the other architectures that have their own syscall.tbl. csky has two architecture specific system calls, which I add to the generic table. The time32, stat64 and rlimit entries in the syscall_abis_32 line are for system calls that were part of the generic ABI when arch/csky got added but are no longer enabled by default for new architectures.

Both the user visible side of asm/unistd.h and the internal syscall table in the kernel should have the same effective contents after this. When asm/syscalls.h is included in kernel/fork.c for the purpose of type checking, the redirection macros cause problems. Move these so only the references get redirected.

riscv: convert to generic syscall table The uapi/asm/unistd_{32,64}.h and asm/syscall_table_{32,64}.h headers can now be generated from scripts/syscall.tbl, which makes this consistent with the other architectures that have their own syscall.tbl. riscv has two extra system call that gets added to scripts/syscall.tbl. The newstat and rlimit entries in the syscall_abis_64 line are for system calls that were part of the generic ABI when riscv64 got added but are no longer enabled by default for new architectures. Both riscv32 and riscv64 also implement memfd_secret, which is optional for all architectures. Unlike all the other 32-bit architectures, the time32 and stat64 sets of syscalls are not enabled on riscv32. Both the user visible side of asm/unistd.h and the internal syscall table in the kernel should have the same effective contents after this. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
