Previously, guest_loaddr was not taken into account when returning an
address from pgb_find_hole when /proc/self/maps was unavailable which
caused an improper guest_base address to be calculated.
This could cause a SIGSEGV later in load_elf_image -> target_mmap for
ET_EXEC type images since the mmap MAP_FIXED flag is specified which
could clobber existing mappings at the address returnd by g2h().

Add --preserve-argv0 in qemu-binfmt-conf.sh to configure the preserve-argv0
flag.
This patch allows to use new flag in AT_FLAGS to detect if
preserve-argv0 is configured for this interpreter:
argv[0] (the full pathname provided by binfmt-misc) is removed and
replaced by argv[1] (the original argv[0] provided by binfmt-misc when
'P'/preserve-arg[0] is set)
For instance with this patch and kernel support for AT_FLAGS:
$ sudo chroot m68k-chroot sh -c 'echo $0'
sh
without this patch:
$ sudo chroot m68k-chroot sh -c 'echo $0'
/usr/bin/sh
The new flag is available in kernel (v5.12) since:
2347961b11d4 ("binfmt_misc: pass binfmt_misc flags to the interpreter")
This can be tested with something like:
# cp ..../qemu-ppc /chroot/powerpc/jessie
# qemu-binfmt-conf.sh --qemu-path / --systemd ppc --credential yes \
--persistent no --preserve-argv0 yes

The status of the gitlab-CI files is currently somewhat confusing, and
it is often not quite clear whether a patch should go via my tree or
via the testing tree of Alex. That situation has grown historically...
Initially, I was the only one using the gitlab-CI, just for my private
repository there. But in the course of time, the gitlab-CI switched to
use the containers from tests/docker/ (which is not part of the gitlab-CI
section in the MAINTAINERS file), and QEMU now even switched to gitlab.com
completely for the repository and will soon use it as its gating CI, too,
so it makes way more sense if the gitlab-ci.yml files belong to the people
who are owning the qemu-project on gitlab.com and take care of the gitlab
CI there. Thus let's merge the gitlab-ci section into the common "test and
build automation" section.
And while we're at it, I'm also removing the line with Fam there for now,
since he was hardly active during the last years in this area anymore.
If he ever gets more time for this part again in the future, we surely
can add the line back again. I'm also removing the Patchew URL from this
section now since Patchew's files are not tracked in the main QEMU repo
and it is also not maintained by Alex, Philippe and myself.
The maintainers of Patchew are still listed more accurately in the wiki on
https://wiki.qemu.org/AdminContacts & https://wiki.qemu.org/Testing/CI/Patchew
instead.
Now to avoid that Alex is listed here in this section alone, Philippe and
I agreed to help as backup maintainers here, too. And Willian volunteered
to be an additional reviewer.

This patch implements Multi Function Timer (MFT) module for NPCM7XX.
This module is mainly used to configure PWM fans. It has just enough
functionality to make the PWM fan kernel module work.
The module takes two input, the max_rpm of a fan (modifiable via QMP)
and duty cycle (a GPIO from the PWM module.) The actual measured RPM
is equal to max_rpm * duty_cycle / NPCM7XX_PWM_MAX_DUTY. The RPM is
measured as a counter compared to a prescaled input clock. The kernel
driver reads this counter and report to user space.

The virt machine already checks KVM_CAP_ARM_VM_IPA_SIZE to get the
upper bound of the IPA size. If that bound is lower than the highest
possible GPA for the machine, then QEMU will error out. However, the
IPA is set to 40 when the highest GPA is less than or equal to 40,
even when KVM may support an IPA limit as low as 32. This means KVM
may fail the VM creation unnecessarily. Additionally, 40 is selected
with the value 0, which means use the default, and that gets around
a check in some versions of KVM, causing a difficult to debug fail.
Always use the IPA size that corresponds to the highest possible GPA,
unless it's lower than 32, in which case use 32. Also, we must still
use 0 when KVM only supports the legacy fixed 40 bit IPA.

Currently the emulated EMAC for sun8i always traverses the transmit queue
from the head when transferring packets. It searches for a list of consecutive
descriptors whichs are flagged as ready for processing and transmits their payloads
accordingly. The controller stops processing once it finds a descriptor that is not
marked ready.
While the above behaviour works in most situations, it is not the same as the actual
EMAC in hardware. Actual hardware uses the TX_CUR_DESC register value to keep track
of the last position in the transmit queue and continues processing from that position
when software triggers the start of DMA processing. The currently emulated behaviour can
lead to packet loss on transmit when software fills the transmit queue with ready
descriptors that overlap the tail of the circular list.
This commit modifies the emulated EMAC for sun8i such that it processes
the transmit queue using the TX_CUR_DESC register in the same way as hardware.

Wrote too much with low-half zip (zip1) with vl % 512 != 0.
Adjust all of the x + (y << s) to x | (y << s) as a style fix.
We only ever have exact overlap between D, M, and N. Therefore
we only need a single temporary, and we do not need to check for
partial overlap.

Missed out on compressing the second half of a predicate
with length vl % 512 > 256.
Adjust all of the x + (y << s) to x | (y << s) as a
general style fix. Drop the extract64 because the input
uint64_t are known to be already zero-extended from the
current size of the predicate.

If the whole SID range (32b) is invalidated (SMMU_CMD_CFGI_ALL),
@end overflows and we fail to handle the command properly.
Once this gets fixed, the current code really is awkward in the
sense it loops over the whole range instead of removing the
currently cached configs through a hash table lookup.
Fix both the overflow and the lookup.

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.

If the asid is not set, do not attempt to locate the key directly
as all inserted keys have a valid asid.
Use g_hash_table_foreach_remove instead.

Unmap notifiers work with an address mask assuming an
invalidation range of a power of 2. Nothing mandates this
in the VIRTIO-IOMMU spec.
So in case the range is not a power of 2, split it into
several invalidations.

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.

This is mainly a stub to make firmware happy. The size of
