[PULL v2 0/4] Fuzzing Patches

Hello Paolo, The following changes since commit 711c0418c8c1ce3a24346f058b001c4c5a2f0f81: Merge remote-tracking branch 'remotes/philmd/tags/mips-20210702' into staging (2021-07-04 14:04:12 +0100) are available in the Git repository at: https://gitlab.com/a1xndr/qemu

[PULL v2 1/4] fuzz: fix sparse memory access in the DMA callback

The code mistakenly relied on address_space_translate to store the length remaining until the next memory-region. We care about this because when there is RAM or sparse-memory neighboring on an MMIO region, we should only write up to the border, to prevent inadvertently invoking MMIO handlers

[PULL v2 3/4] fuzz: make object-name matching case-insensitive

We have some configs for devices such as the AC97 and ES1370 that were not matching memory-regions correctly, because the configs provided lowercase names. To resolve these problems and prevent them from occurring again in the future, convert both the pattern and names to lower-case, prior to

[PATCH 3/4] configure: Fix the default setting of the "xen" feature

The "xen" variable should either contain "enabled", "disabled" or nothing (for auto detection). But when the user currently runs the configure script with --without-default-features, it gets set to "no" instead. This does not work as expected, the feature will still be enabled if the Xen headers

[PATCH for-6.2 10/34] target/arm: Fix VLDRB/H/W for predicated elements

For vector loads, predicated elements are zeroed, instead of retaining their previous values (as happens for most data processing operations). This means we need to distinguish "beat not executed due to ECI" (don't touch destination element) from "beat executed but predicated out" (zero
