Hello,
I've noticed that the command
qemu-system-xtensa -cpu help
no longer prints anything. Apparently because cpu_list is no longer defined
in list_cpus inside softmmu/cpus.c
Bisection points to the following commit:
e0220bb5b200 ("softmmu: Build target-agnostic objects once")
Reverting the
When s->shdr_num is 0 we'll add 0 bytes of section headers which is
equivalent to not adding section headers but with the multiplication
we can remove a if/else.

There's no need to have a gigantic if in there let's move the elf
32/64 bit logic into the section, segment or note code.

Just like with the other write functions let's move the 32/64 bit elf
handling to a function to improve readability.

Checking d_class in dump_info leads to lengthy conditionals so let's
shorten things a bit by introducing a helper function.

There's no need to have phdr_num and sh_info at the same time. We can
make phdr_num 32 bit and set PN_XNUM when we write the header if
phdr_num >= PN_XNUM.

The dump/dump.c file has lots of duplicated code for handling 64 and
32 bit elf files. Additionally there are many instances where code can
be improved by adding a variable to avoid having to specify the same
calculation or check over and over.
This series is the cleanup step onto which my series
Offset calculations are easy enough to get wrong. Let's add a few
variables to make moving around elf headers and data sections easier.

There are cases that malicious virtual machine can cause CPU stuck (due
to event windows don't open up), e.g., infinite loop in microcode when
nested #AC (CVE-2015-5307). No event window means no event (NMI, SMI and
IRQ) can be delivered. It leads the CPU to be unavailable to host or
other VMs.
Notify VM exit is introduced to mitigate the potential DOS attach from
malicious VM. This series is the userspace part to enable this feature
through a new KVM capability KVM_CAP_X86_NOTIFY_VMEXIT. The
corresponding KVM patch series is available at
