96f4a70d8e [S390] topology: export cpu topology via proc/sysinfo
Export the cpu configuration topology via sysinfo. Two new lines are
introduced:

CPU Topology HW:      0 0 0 4 6 4
CPU Topology SW:      0 0 0 0 4 24

The HW line describes the cpu topology nesting levels when the maximum
nesting level is used to get the corresponding SYSIB.
The SW line describes what Linux is actually using. In this case it
supports only two levels (CONFIG_SCHED_BOOK off) and therefore the
hardware folded the two lower levels in the SYSIB response block.

0576fc703a [S390] smp: use correct cpu address in print_cpu_info()
Up to now print_cpu_info() uses the cpu address stored in it's local
lowcore to print a message to the console. The cpu address in the
lowcore is (in this case) however not the physical cpu address of the
local cpu. It's the address of the cpu that issued the sigp restart
which started the local cpu.
Fix this by using the store cpu address instruction instead.
It's not that anybody really cares since this is broken since more than
ten years...

6931be0803 [S390] cpu hotplug/idle: move cpu_die call to enabled context
There is no difference if cpu_die is called from enabled or disabled
context. Except that the fast_gup code might be called via
cpu_die -> idle_task_exit -> __mm_drop -> crst_table_free. Which in
turn grabs and releases a spinlock using the _bh ops, which is not
allowed in irq disabled context, since spin_unlock_bh will
unconditionally enable interrupts again.
To get rid of the warning emitted by the softirq code just move the
code to enabled context.

In this case this doesn't fix a bug, we just get rid of a warning.

77db5cbd29 KVM: MCE: Send SRAR SIGBUS directly
Originally, SRAR SIGBUS is sent to QEMU-KVM via touching the poisoned
page. But commit 96054569190bdec375fe824e48ca1f4e3b53dd36 prevents the
signal from being sent. So now the signal is sent via
force_sig_info_fault directly.

[marcelo: use send_sig_info instead]

5854dbca9b KVM: MCE: Add MCG_SER_P into KVM_MCE_CAP_SUPPORTED
Now we have MCG_SER_P (and corresponding SRAO/SRAR MCE) support in
kernel and QEMU-KVM, the MCG_SER_P should be added into
KVM_MCE_CAP_SUPPORTED to make all these code really works.

395c6b0a9d KVM: Disable interrupts around get_kernel_ns()
get_kernel_ns() wants preemption disabled.  It doesn't make a lot of sense
during the get/set ioctls (no way to make them non-racy) but the callee wants
it.
