Samuel Tardieu 8a780cd212 docs: use "buses" rather than "busses"
If "busses" might be encountered as a plural of "bus" (5 instances),
the correct spelling is "buses" (26 instances). Fixing those 5
instances makes the doc more consistent.

Max Erenberg 2c5107e1b4 edu: fix DMA range upper bound check
The edu_check_range function checks that start <= end1 < end2, where
end1 is the upper bound (exclusive) of the guest-supplied DMA range and
end2 is the upper bound (exclusive) of the device's allowed DMA range.
When the guest tries to transfer exactly DMA_SIZE (4096) bytes, end1
will be equal to end2, so the check fails and QEMU aborts with this
puzzling error message (newlines added for formatting):

  qemu: hardware error: EDU: DMA range
    0x0000000000040000-0x0000000000040fff out of bounds
   (0x0000000000040000-0x0000000000040fff)!

By checking end1 <= end2 instead, guests will be allowed to transfer
exactly 4096 bytes. It is not necessary to explicitly check for
start <= end1 because the previous two checks (within(addr, start, end2)
and end1 > addr) imply start < end1.

Pavel Pisa 25145a7d77 hw/net/can/sja1000: fix bug for single acceptance filter and standard frame
A CAN sja1000 standard frame filter mask has been computed and applied
incorrectly for standard frames when single Acceptance Filter Mode
(MOD_AFM = 1) has been selected. The problem has not been found
by Linux kernel testing because it uses dual filter mode (MOD_AFM = 0)
and leaves falters fully open.

The problem has been noticed by Grant Ramsay when testing with Zephyr
RTOS which uses single filter mode.

Philippe Mathieu-Daudé 287fa32324 hw: Simplify accesses to the CPUState::'start-powered-off' property
The 'start-powered-off' property has been added to ARM CPUs in
commit 5de164304a ("arm: Allow secondary KVM CPUs to be booted
via PSCI"), then eventually got generalized to all CPUs in commit
c1b701587e ("target/arm: Move start-powered-off property to generic
CPUState"). Since all CPUs have it, no need to check whether it is
available. Updating this property can't fail, so use &error_abort.
