as follows, replace msleep() with usleep_range().
msleep(1~20) may not do what the caller intends, and
will often sleep longer (~20 ms actual sleep for any

We use alternatives_text_reserved() to check if the address is in
the fixed pieces of alternative reserved, but the problem is that
we don't hold the smp_alt mutex when call this function. So the list
traversal may encounter a deleted list_head if another path is doing
alternatives_smp_module_del().
One solution is that we can hold smp_alt mutex before call this
function, but the difficult point is that the callers of this
functions, arch_prepare_kprobe() and arch_prepare_optimized_kprobe(),
are called inside the text_mutex. So we must hold smp_alt mutex
before we go into these arch dependent code. But we can't now,
the smp_alt mutex is the arch dependent part, only x86 has it.
Maybe we can export another arch dependent callback to solve this.
But there is a simpler way to handle this problem. We can reuse the
text_mutex to protect smp_alt_modules instead of using another mutex.
And all the arch dependent checks of kprobes are inside the text_mutex,
so it's safe now.

The build messages for fdimage/isoimage generation are pretty unstructured,
just the raw shell command blocks are printed.
Emit shortened messages similar to existing kbuild messages, and move
the Makefile commands into a separate shell script - which is much
easier to handle.
This patch factors out the commands used for fdimage/isoimage generation
from arch/x86/boot/Makefile to a new script arch/x86/boot/genimage.sh.
Then it adds the new kbuild command 'genimage' which invokes the new script.
All fdimages/isoimage files are now generated by a call to 'genimage' with
different parameters.
Now 'make isoimage' becomes:

we allocate the mem_section array dynamically in sparse_memory_present_with_active_regions(),
but some architectures, like arm64, don't call the routine to initialize sparsemem.
Let's move the initialization into memory_present() it should cover all

Bits 19:16 of LAR's result are undefined, and some upcoming
improvements to the test case seem to trigger this. Mask off those
bits to avoid spurious failures.
commit 5b781c7e31 ("x86/tls: Forcibly set the accessed bit in TLS
segments") adds a valid case in which LAR's output doesn't quite
agree with set_thread_area()'s input. This isn't triggered in the
test as is, but it will be if we start calling set_thread_area()
with the accessed bit clear. Work around this discrepency.

The AMD severity grading function was introduced in kernel 4.1. The
current logic can possibly give MCE_AR_SEVERITY for uncorrectable
errors in kernel context. The system may then get stuck in a loop as
memory_failure() will try to handle the bad kernel memory and find it
busy.
Return MCE_PANIC_SEVERITY for all UC errors IN_KERNEL context on AMD
systems.
After:
b2f9d678e2 ("x86/mce: Check for faults tagged in EXTABLE_CLASS_FAULT exception table entries")
was accepted in v4.6, this issue was masked because of the tail-end attempt
at kernel mode recovery in the #MC handler.
However, uncorrectable errors IN_KERNEL context should always be considered
unrecoverable and cause a panic.

At least one Dell XPS13 9360 is reported to have serious issues with
the Low Power S0 Idle _DSM interface and since this machine model
generally can do ACPI S3 just fine, add a blacklist entry to disable
that interface for Dell XPS13 9360.
Fixes: 8110dd281e (ACPI / sleep: EC-based wakeup from suspend-to-idle on recent systems)

In preparation for unconditionally passing the struct timer_list pointer to
all timer callbacks, switch to using the new timer_setup() and from_timer()
to pass the timer pointer explicitly.
This refactors the discover_timer to remove the needless locking and
state machine used for synchronizing timer death. Using del_timer_sync()
will already do the right thing.
