Richard Henderson 87e9bf2323 linux-user: Split out do_prctl and subroutines
Since the prctl constants are supposed to be generic, supply
any that are not provided by the host.

Split out subroutines for PR_GET_FP_MODE, PR_SET_FP_MODE,
PR_GET_VL, PR_SET_VL, PR_RESET_KEYS, PR_SET_TAGGED_ADDR_CTRL,
PR_GET_TAGGED_ADDR_CTRL.  Return EINVAL for guests that do
not support these options rather than pass them on to the host.

LemonBoy ce437484fc linux-user: Correct definition of stack_t
Some platforms used the wrong definition of stack_t where the flags and
size fields were swapped or where the flags field had type ulong instead
of int.

Due to the presence of padding space in the structure and the prevalence
of little-endian machines this problem went unnoticed for a long time.

The type definitions have been cross-checked with the ones defined in
the Linux kernel v5.9, plus some older versions for a few architecture
that have been removed and Xilinx's kernel fork for NiosII [1].

The bsd-user headers remain unchanged as I don't know if they are wrong
or not.

Filip Bozuta fcb6fcf63b linux-user: Add generic 'termbits.h' for some archs
This patch introduces a generic 'termbits.h' file for following
archs: 'aarch64', 'arm', 'i386, 'm68k', 'microblaze', 'nios2',
'openrisc', 'riscv', 's390x', 'x86_64'.

Since all of these archs have the same termios flag values and
same ioctl_tty numbers, there is no need for a separate 'termbits.h'
file for each one of them. For that reason one generic 'termbits.h'
file was added for all of them and an '#include' directive was
added for this generic file in every arch 'termbits.h' file.

Also, some of the flag values that were missing were added in this
generic file so that it matches the generic 'termibts.h' and 'ioctls.h'
files from the kernel: 'asm-generic/termbits.h' and 'asm-generic/ioctls.h'.

Filip Bozuta 02e5d7d78e linux-user: Add strace support for printing arguments of syscalls used to lock and unlock memory
This patch implements strace argument printing functionality for following syscalls:

    * mlock, munlock, mlockall, munlockall - lock and unlock memory

       int mlock(const void *addr, size_t len)
       int munlock(const void *addr, size_t len)
       int mlockall(int flags)
       int munlockall(void)
       man page: https://man7.org/linux/man-pages/man2/mlock.2.html

Implementation notes:

    Syscall mlockall() takes an argument that is composed of predefined values
    which represent flags that determine the type of locking operation that is
    to be performed. For that reason, a printing function "print_mlockall" was
    stated in file "strace.list". This printing function uses an already existing
    function "print_flags()" to print the "flags" argument.  These flags are stated
    inside an array "mlockall_flags" that contains values of type "struct flags".
    These values are instantiated using an existing macro "FLAG_TARGET()" that
    crates aproppriate target flag values based on those defined in files
    '/target_syscall.h'. These target flag values were changed from
    "TARGET_MLOCKALL_MCL*" to "TARGET_MCL_*" so that they can be aproppriately set
    and recognised in "strace.c" with "FLAG_TARGET()". Value for "MCL_ONFAULT"
    was added in this patch. This value was also added in "syscall.c" in function
    "target_to_host_mlockall_arg()". Because this flag value was added in kernel
    version 4.4, it is enwrapped in an #ifdef directive (both in "syscall.c" and
    in "strace.c") as to support older kernel versions.
    The other syscalls have only primitive argument types, so the
    rest of the implementation was handled by stating an appropriate
    printing format in file "strace.list". Syscall mlock2() is not implemented in
    "syscall.c" and thus it's argument printing is not implemented in this patch.

Marc-André Lureau 3a30446aed meson: linux-user
The most interesting or most complicated part here is the syscall_nr.h
generators.  In order to keep the generation logic all in meson.build,
I am adding to config_target the name of the .tbl file, and making the
generated file syscall<SUFFIX>_nr.h for input file syscall<SUFFIX>.tbl.

For architectures where the input file is not named syscall_nr.tbl,
syscall_nr.h has to be a source file; it's just a forwarder for x86
(i386/x86_64), while for MIPS64 it chooses between N32 and N64 ABIs.

Lluís Vilanova 460c579f3d build: [linux-user] Rename "syscall.h" to "target_syscall.h" in target directories
This fixes double-definitions in linux-user builds when using the UST
tracing backend (which indirectly includes the system's "syscall.h").

Tom Musta 6f6a40328b linux-user: Support target-to-host translation of mlockall argument
The argument to the mlockall system call is not necessarily the same on
all platforms and thus may require translation prior to passing to the
host.

For example, PowerPC 64 bit platforms define values for MCL_CURRENT
(0x2000) and MCL_FUTURE (0x4000) which are different from Intel platforms
(0x1 and 0x2, respectively)

Riku Voipio cbc14e6f28 linux-user: set minimum kernel version to 2.6.32
Popular glibc based distributions[1] require minimum
2.6.32 as kernel version. For some targets 2.6.18
would be enough, but dropping so low would mean some
suboptimal system calls could get used.

Set the minimum kernel advertized to 2.6.32 for
all architectures but aarch64 to ensure working qemu
linux-user in case host kernel is older.

Peter Maydell 6291ad77d7 linux-user: Move cpu_clone_regs() and cpu_set_tls() into linux-user
The functions cpu_clone_regs() and cpu_set_tls() are not purely CPU
related -- they are specific to the TLS ABI for a a particular OS.
Move them into the linux-user/ tree where they belong.

target-lm32 had entirely unused implementations, since it has no
linux-user target; just drop them.

Anthony Liguori c227f0995e Revert "Get rid of _t suffix"
In the very least, a change like this requires discussion on the list.

The naming convention is goofy and it causes a massive merge problem.  Something
like this _must_ be presented on the list first so people can provide input
and cope with it.

This reverts commit 99a0949b72.
