Hi All,
I had seen the following lockdep splat when booting a guest on my
Kunpeng 920 with GICv4 enabled. I can also trigger the same splat
on v5.5 so it should already exist in the kernel for a while. I'm
not sure what the exact problem is and hope someone can have a look!
Thanks,
Zenghui

The mtk-dpi driver still uses the drm_encoder API which is now somewhat

Fix sockmap tests which rely on old bpf_prog_dispatch behaviour.
In the first case, the tests check that detaching without giving
a program succeeds. Since these are not the desired semantics,

Upstream VirtualBox has defined and is using a few new request types for
vmmdev requests passed through /dev/vboxguest to the hypervisor.
Add the defines for these to vbox_vmmdev_types.h and add add them to the
whitelists of vmmdev requests which userspace is allowed to make.
BugLink: https://bug
Add vbg_set_host_capabilities() helper function, this is a preparation
patch for adding support for the VBGL_IOCTL_GUEST_CAPS_ACQUIRE ioctl.

Hello Al,
You are the closest I could find to a romfs maintainer. get_maintainer.pl
doesn't appear to list any.
This attempted performance regression fix didn't generate much feedback
(to say the least). It's however a real issue for us when supporting a legacy
product where we don't have the lux

Looks good, but maybe you could also update the comments in the code (see
remarks below)?

PPC_DEBUG_FEATURE_DATA_BP_DAWR_ARCH_31 can be used to determine
whether we are running on an ISA 3.1 compliant machine. Which is
needed to determine DAR behaviour, 512 byte boundary limit etc.
This was requested by Pedro Miraglia Franco de Carvalho for
extending watchpoint features in gdb. Note tha

Is there a format (or other function) that lets me
print strings without an \0 terminator using an explicit length arg instead?
Something like:
printk("%s...", str, str_len); /* replace ... */
or some other funktion perhaps ?
