ea042c53f4 spapr: Do NVDIMM/PC-DIMM device hotplug sanity checks at pre-plug only
Pre-plug of a memory device, be it an NVDIMM or a PC-DIMM, ensures
that the memory slot is available and that addresses don't overlap
with existing memory regions. The corresponding DRCs in the LMB
and PMEM namespaces are thus necessarily attachable at plug time.

Pass &error_abort to spapr_drc_attach() in spapr_add_lmbs() and
spapr_add_nvdimm(). This allows to greatly simplify error handling
on the plug path.

9e4dc0a1c2 spapr: Do PCI device hotplug sanity checks at pre-plug only
The PHB acts as the hotplug handler for PCI devices. It does some
sanity checks on DR enablement, PCI bridge chassis numbers and
multifunction. These checks are currently performed at plug time,
but they would best sit in a pre-plug handler in order to error
out as early as possible.

Create a spapr_pci_pre_plug() handler and move all the checking
there. Add a check that the associated DRC doesn't already have
an attached device. This is equivalent to the slot availability
check performed by do_pci_register_device() upon realization of
the PCI device.

This allows to pass &error_abort to spapr_drc_attach() and to end
up with a plug handler that doesn't need to report errors anymore.

484d774c3a spapr/xive: Turn some sanity checks into assertions
The sPAPR XIVE device is created by the machine in spapr_irq_init().
The latter overrides any value provided by the user with -global for
the "nr-irqs" and "nr-ends" properties with strictly positive values.

It seems reasonable to assume these properties should never be 0,
which wouldn't make much sense by the way.

a998de0dcd CODING_STYLE.rst: Be less strict about 80 character limit
Relax the wording about line lengths a little bit; this goes with the
checkpatch changes to warn at 100 characters rather than 80.

(Compare the Linux kernel commit bdc48fa11e46f8; our coding style is
not theirs, but the rationale is good and applies to us too.)

f6a3c86ebd hw/pci-host/pam: Replace magic number by PAM_REGIONS_COUNT definition
While this change helps triskaidekaphobic developers, it
is a good practice to avoid magic values and using constant
definitions instead.

Introduce the PAM_REGIONS_COUNT and use it. No logical change.

fa647905e6 qemu-options.hx: Fix minor issues in icount documentation
The documentation for the icount documentation has some minor issues:
 * in a couple of places it says "sleep=on|off" when in the context of the
   sentence it means specifically "sleep=on"
 * the synopsis line for the documentation has drifted out of sync
   with the synopsis line in the DEF() macro (used for "-help" output)
 * the synopsis line in the DEF() macro is missing a "][" between
   the sleep= part and the rr= part
 * the synopsis line doesn't indicate that rrsnapshot is an optional
   part of the rr=mode,rrfile=filename subgrouping
 * we don't document that sleep=on can't be used with shift=auto
   or align=on
 * the rr option description had some minor grammar and formatting
   errors and was a bit terse
 * in commit f1f4b57e88 in 2015 the documentation of the sleep=
   suboption got added between the two paragraphs defining general
   behaviour of the icount option. This meant that the second
   paragraph talking about the behaviour of "this option" reads as
   if it's talking about sleep=on, when it's really describing -icount
   as a whole. The paragraph is better moved back up to above the
   sleep= section.
 * the summary text displayed in "-help" output didn't mention
   the record-and-replay part

Fix these errors.

6f8ddc2a89 target/i386: tracing: format length values as hex
Three trace events had a literal "0x" prefix but the 'len' values were
formatted in decimal base.  Keep the prefix and format the numbers as
hex, as is usually the case for length of memory regions.
