Subject: [PATCH] gdb: Fix an assertion failure in the gdb's copy_type()
This is a backported patch from gdb. Without the patch, the following
crash command may abort due to an assertion failure in the gdb's
copy_type():
crash> px __per_cpu_start:0
gdbtypes.c:5505: internal-error: type* copy_type(const type*): Assertion `TYPE_OBJFILE_OWNED (type)' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n)
The gdb commit 8e2da1651879 ("Fix assertion failure in copy_type")
solved the current issue.

Subject: [PATCH] Fix for "bt" command printing "bogus exception frame" warning
Currently, the "bt" command may print a bogus exception frame
and the remaining frame will be truncated on x86_64 when using the
"virsh send-key <kvm guest> KEY_LEFTALT KEY_SYSRQ KEY_C" command
to trigger a panic from the KVM host. For example:

Subject: [PATCH] Fix for "bt" command unnecessarily printing an exception
frame
Kernel commit 7d65f4a65532 ("irq: Consolidate do_softirq() arch overriden
implementations") renamed the call_softirq to do_softirq_own_stack, and
there is no exception frame also when coming from do_softirq_own_stack.
Without the patch, crash may unnecessarily output an exception frame with
a warning as below:
