hw/arm/smmuv3: Enforce invalidation on a power of two range
As of today, the driver can invalidate a number of pages that is
not a power of 2. However IOTLB unmap notifications and internal
IOTLB invalidations work with masks leading to erroneous
invalidations.
In case the range is not a power of 2, split invalidations into
power of 2 invalidations.
When looking for a single page entry in the vSMMU internal IOTLB,
let's make sure that if the entry is not found using a
g_hash_table_remove() we iterate over all the entries to find a
potential range that overlaps it.

dma: Introduce dma_aligned_pow2_mask()
Currently get_naturally_aligned_size() is used by the intel iommu
to compute the maximum invalidation range based on @size which is
a power of 2 while being aligned with the @start address and less
than the maximum range defined by @gaw.
This helper is also useful for other iommu devices (virtio-iommu,
SMMUv3) to make sure IOMMU UNMAP notifiers only are called with
power of 2 range sizes.
Let's move this latter into dma-helpers.c and rename it into
dma_aligned_pow2_mask(). Also rewrite the helper so that it
accomodates UINT64_MAX values for the size mask and max mask.
It now returns a mask instead of a size. Change the caller.

gitlab-ci.yml: Add jobs to test CFI flags
QEMU has had options to enable control-flow integrity features
for a few months now. Add two sets of build/check/acceptance
jobs to ensure the binary produced is working fine.
The three sets allow testing of x86_64 binaries for x86_64, s390x,
ppc64 and aarch64 targets

gitlab-ci.yml: Allow custom # of parallel linkers
Define a new variable LD_JOBS, that can be used to select
the maximum number of linking jobs to be executed in parallel.
If the variable is not defined, maintain the default given by
make -j
Currently, make parallelism at build time is based on the number
of cpus available.
This doesn't work well with LTO at linking, because with LTO the
linker has to load in memory all the intermediate object files
for optimization.
The end result is that, if the gitlab runner happens to run two
linking processes at the same time, the job will fail with an
out-of-memory error,
This patch leverages the ability to maintain high parallelism at
compile time, but limit the number of linkers executed in parallel.

hw/timer/renesas_tmr: Fix use of uninitialized data in read_tcnt()
The read_tcnt() function calculates the TCNT register values for the
two channels of the timer module; it sets these up in the local
tcnt[] array, and eventually returns either one or both of them,
depending on whether the access is 8 or 16 bits. However, not all of
the code paths through this function set both elements of this array:
if the guest has programmed the TCCR.CSS register fields to values
which are either documented as not to be used or which QEMU does not
implement, then the function will return uninitialized data. (This
was spotted by Coverity.)
Add the missing CSS cases to this code, so that we return a
consistent value instead of uninitialized data, and so the code
structure indicates what's happening.

hw/misc: Model KCS devices in the Aspeed LPC controller
Keyboard-Controller-Style devices for IPMI purposes are exposed via LPC
IO cycles from the BMC to the host.
Expose support on the BMC side by implementing the usual MMIO
behaviours, and expose the ability to inspect the KCS registers in
"host" style by accessing QOM properties associated with each register.
The model caters to the IRQ style of both the AST2600 and the earlier
SoCs (AST2400 and AST2500). The AST2600 allocates an IRQ for each LPC
sub-device, while there is a single IRQ shared across all subdevices on
the AST2400 and AST2500.

hw/block/nvme: support namespace detach
Given that now we have nvme-subsys device supported, we can manage
namespace allocated, but not attached: detached. This patch introduced
a parameter for nvme-ns device named 'detached'. This parameter
indicates whether the given namespace device is detached from
a entire NVMe subsystem('subsys' given case, shared namespace) or a
controller('bus' given case, private namespace).
- Allocated namespace
1) Shared ns in the subsystem 'subsys0':
-device nvme-ns,id=ns1,drive=blknvme0,nsid=1,subsys=subsys0,detached=true
2) Private ns for the controller 'nvme0' of the subsystem 'subsys0':
-device nvme-subsys,id=subsys0
-device nvme,serial=foo,id=nvme0,subsys=subsys0
-device nvme-ns,id=ns1,drive=blknvme0,nsid=1,bus=nvme0,detached=true
3) (Invalid case) Controller 'nvme0' has no subsystem to manage ns:
-device nvme,serial=foo,id=nvme0
-device nvme-ns,id=ns1,drive=blknvme0,nsid=1,bus=nvme0,detached=true

hw/block/nvme: refactor nvme_dma
The nvme_dma function doesn't just do DMA (QEMUSGList-based) memory transfers;
it also handles QEMUIOVector copies.
Introduce the NvmeTxDirection enum and rename to nvme_tx. Remove mapping
of PRPs/SGLs from nvme_tx and instead assert that they have been mapped
previously. This allows more fine-grained use in subsequent patches.
Add new (better named) helpers, nvme_{c2h,h2c}, that does both PRP/SGL
mapping and transfer.

hw/block/nvme: align zoned.zasl with mdts
ZASL (Zone Append Size Limit) is defined exactly like MDTS (Maximum Data
Transfer Size), that is, it is a value in units of the minimum memory
page size (CAP.MPSMIN) and is reported as a power of two.
The 'mdts' nvme device parameter is specified as in the spec, but the
'zoned.append_size_limit' parameter is specified in bytes. This is
suboptimal for a number of reasons:
1. It is just plain confusing wrt. the definition of mdts.
2. There is a lot of complexity involved in validating the value; it
must be a power of two, it should be larger than 4k, if it is zero
we set it internally to mdts, but still report it as zero.
3. While "hw/block/nvme: improve invalid zasl value reporting"
slightly improved the handling of the parameter, the validation is
still wrong; it does not depend on CC.MPS, it depends on
CAP.MPSMIN. And we are not even checking that it is actually less
than or equal to MDTS, which is kinda the *one* condition it must
satisfy.
Fix this by defining zasl exactly like mdts and checking the one thing
that it must satisfy (that it is less than or equal to mdts). Also,
change the default value from 128KiB to 0 (aka, whatever mdts is).
