The hardware spec defines max_average_bw == 0 as "unlimited bandwidth".
max_average_bw is calculated as `ceil / BYTES_IN_MBIT`, which can become
0 when ceil is small, leading to an undesired effect of having no
bandwidth limit.
This commit fixes it by rounding up small values of ceil to 1 Mbit/s.

In XFS, we always update the inode change and modification time when
any fallocate() operation succeeds. Furthermore, as various
fallocate modes can change the file contents (extending EOF,
punching holes, zeroing things, shifting extents), we should drop
file privileges like suid just like we do for a regular write().
There's already a VFS helper that figures all this out for us, so
use that.
The net effect of this is that we no longer drop suid/sgid if the
caller is root, but we also now drop file capabilities.
We also move the xfs_update_prealloc_flags() function so that it now
is only called by the scope that needs to set the the prealloc flag.

automatically and does not need this. There, it is completely fine not

audit: improve audit queue handling when "audit=1" on cmdline
The recently added configuration option for Cortex A510 erratum 2051678 does
not have a "default y" unlike other errata fixes. This appears to simply be
an oversight since the help text suggests enabling the option if unsure and
there's nothing in the commit log to suggest it is intentional.

In kvm_arch_vcpu_ioctl_run() we enter an RCU extended quiescent state
(EQS) by calling guest_enter_irqoff(), and unmasked IRQs prior to
exiting the EQS by calling guest_exit(). As the IRQ entry code will not
wake RCU in this case, we may run the core IRQ code and IRQ handler
without RCU watching, leading to various potential problems.
Additionally, we do not inform lockdep or tracing that interrupts will
be enabled during guest execution, which caan lead to misleading traces
and warnings that interrupts have been enabled for overly-long periods.
This patch fixes these issues by using the new timing and context
entry/exit helpers to ensure that interrupts are handled during guest
vtime but with RCU watching, with a sequence:
guest_timing_enter_irqoff();
guest_state_enter_irqoff();
< run the vcpu >
guest_state_exit_irqoff();
< take any pending IRQs >
guest_timing_exit_irqoff();
Since instrumentation may make use of RCU, we must also ensure that no
instrumented code is run during the EQS. I've split out the critical
section into a new kvm_arm_enter_exit_vcpu() helper which is marked
noinstr.
