Frank Chang 7b07a37c2c target/riscv: rvv-1.0: introduce writable misa.v field
Implementations may have a writable misa.v field. Analogous to the way
in which the floating-point unit is handled, the mstatus.vs field may
exist even if misa.v is clear.

Richard Henderson a3310c0397 linux-user: Move syscall error detection into safe_syscall_base
The current api from safe_syscall_base() is to return -errno, which is
the interface provided by *some* linux kernel abis.  The wrapper macro,
safe_syscall(), detects error, stores into errno, and returns -1, to
match the api of the system syscall().

For those kernel abis that do not return -errno natively, this leads
to double syscall error detection.  E.g. Linux ppc64, which sets the
SO flag for error.

Simplify the usage from C by moving the error detection into assembly,
and usage from assembly by providing a C helper with which to set errno.

Paolo Bonzini 4da270be1c configure: unify x86_64 and x32
The only difference between the two, as far as either configure or
Meson are concerned, is in the multilib flags passed to the compiler.

For QEMU, this fixes the handling of TYPE_OLDDEVT in
include/exec/user/thunk.h and enables testing of dirty ring buffer,
because both are using HOST_X86_64.

For tests/tcg, this means that on a hypothetical x32 host the
cross compiler will not be used to build the tests.

The only difference between the two, as far as either configure or

For tests/tcg, specify the endianness explicitly on the command line;
for configure, do the same so that it is possible to have --cpu=ppc64le
on a bigendian system or vice versa.  Apart from this, cpu=ppc64le can
be normalized to ppc64 also in configure and not just in the meson
cross file.

Paolo Bonzini ba7c60c203 configure: make $targetos lowercase, use windows instead of MINGW32
targetos is already mostly the same as Meson host_machine.system(),
just in CamelCase.  Adjust Windows, which is different, and switch to
lowercase to match Meson.

Cédric Le Goater 0e6232bc3c ppc/pnv: Use QOM hierarchy to scan PEC PHB4 devices
When -nodefaults is supported for PHB4 devices, the pecs array under
the chip will be empty. This will break the 'info pic' HMP command.

Do a QOM loop on the chip children and look for PEC PHB4 devices
instead.

Cédric Le Goater aa8cc84d88 ppc/pnv: Compute the PHB index from the PHB4 PEC model
Use the num_stacks class attribute to compute the PHB index depending
on the PEC index :

  * PEC0 provides 1 PHB  (PHB0)
  * PEC1 provides 2 PHBs (PHB1 and PHB2)
  * PEC2 provides 3 PHBs (PHB3, PHB4 and PHB5)

The routine pnv_pec_phb_offset() is a bit complex but it also prepares
ground for PHB5 which has a different layout of stacks: 3 per PECs.

Cédric Le Goater cf0ee6955c ppc/pnv: Introduce a num_stack class attribute
Each PEC device of the POWER9 chip has a predefined number of stacks,
equivalent of a root port complex:

  PEC0 -> 1 stack
  PEC1 -> 2 stacks
  PEC2 -> 3 stacks

Introduce a class attribute to hold these values and remove the
"num-stacks" property.
