mem-prealloc: fix sysconf(_SC_NPROCESSORS_ONLN) failure case.

This was spotted by Coverity, in case where sysconf(_SC_NPROCESSORS_ONLN)
fails and returns -1. This results in memset_num_threads getting set to -1.
Which we then pass to g_new0().
The patch replaces MAX_MEM_PREALLOC_THREAD_COUNT macro with a function call
get_memset_num_threads() to handle sysconf() failure gracefully. In case
sysconf() fails, we fall back to single threaded.

(Spotted by Coverity, CID 1372465.)

os: don't corrupt pre-existing memory-backend data with prealloc

When using a memory-backend object with prealloc turned on, QEMU
will memset() the first byte in every memory page to zero. While
this might have been acceptable for memory backends associated
with RAM, this corrupts application data for NVDIMMs.

Instead of setting every page to zero, read the current byte
value and then just write that same value back, so we are not
corrupting the original data. Directly write the value instead
of memset()ing it, since there's no benefit to memset for a
single byte write.

mem-prealloc: reduce large guest start-up and migration time.

Using "-mem-prealloc" option for a large guest leads to higher guest
start-up and migration time. This is because with "-mem-prealloc" option
qemu tries to map every guest page (create address translations), and
make sure the pages are available during runtime. virsh/libvirt by
default, seems to use "-mem-prealloc" option in case the guest is
configured to use huge pages. The patch tries to map all guest pages
simultaneously by spawning multiple threads. Currently limiting the
change to QEMU library functions on POSIX compliant host only, as we are
not sure if the problem exists on win32. Below are some stats with
"-mem-prealloc" option for guest configured to use huge pages.

Changed in v2:
- modify number of memset threads spawned to min(smp_cpus, 16).
- removed 64GB memory restriction for spawning memset threads.

Changed in v3:
- limit number of threads spawned based on
min(sysconf(_SC_NPROCESSORS_ONLN), 16, smp_cpus)
- implement memset thread specific siglongjmp in SIGBUS signal_handler.

Changed in v4
- remove sigsetjmp/siglongjmp and SIGBUS unblock/block for main thread
as main thread no longer touches any pages.
- simplify code my returning memset_thread_failed status from
touch_all_pages.

cpus: remove ugly cast on sigbus_handler

The cast is there because sigbus_handler is invoked via sigfd_handler.
But it feels just wrong to use struct qemu_signalfd_siginfo in the

Instead, do a simple-minded conversion of qemu_signalfd_siginfo to
siginfo_t.

fix qemu exit on memory hotplug when allocation fails at prealloc time

When adding hostmem backend at runtime, QEMU might exit with error:
"os_mem_prealloc: Insufficient free host memory pages available to allocate guest RAM"

It happens due to os_mem_prealloc() not handling errors gracefully.

Fix it by passing errp argument so that os_mem_prealloc() could
report error to callers and undo performed allocation when
os_mem_prealloc() fails.
