The injected badrange entries can only be cleared from the kernel's
accounting by writing to the affected blocks, so when such a write sends
the clear errror DSM to nfit_test, also clear the ranges from
nfit_test's badrange list. This lets an 'ARS Inject error status' DSM to
return the correct status, omitting the cleared ranges.

Now that we're reusing the badrange functions for nfit_test, and that
exposes badrange injection/clearing to userspace via the DSM paths, it
is plausible that a user may call the clear DSM multiple times. Since it
is harmless to do so, we can remove the WARN in badrange_forget.

Given that we now how have two mechanisms for a DIMM to indicate that it
is locked:
* NVDIMM_FAMILY_INTEL 'get_config_size' _DSM command
* ACPI 6.2 Label Storage Read / Write commands
...export the generic libnvdimm DIMM status in a new 'flags' attribute.
This attribute can also reflect the 'alias' state which indicates
whether the nvdimm core is enforcing labels for aliased-region-capacity
that the given dimm is an interleave-set member.

ACPI 6.2 adds support for named methods to access the label storage area
of an NVDIMM. We prefer these new methods if available and otherwise
fallback to the NVDIMM_FAMILY_INTEL _DSMs. The kernel ioctls,
ND_IOCTL_{GET,SET}_CONFIG_{SIZE,DATA}, remain generic and the driver
translates the 'package' payloads into the NVDIMM_FAMILY_INTEL 'buffer'
format to maintain compatibility with existing userspace and keep the
output buffer parsing code in the driver common.
The output payloads are mostly compatible save for the 'label area
locked' status that moves from the 'config_size' (_LSI) command to the
'config_read' (_LSR) command status.

The set of valid sequence numbers is {1,2,3}. The specification
indicates that an implementation should consider 0 a sign of a critical
error:
UEFI 2.7: 13.19 NVDIMM Label Protocol
Software never writes the sequence number 00, so a correctly
check-summed Index Block with this sequence number probably indicates a
critical error. When software discovers this case it treats it as an
invalid Index Block indication.
While the expectation is that the invalid block is just thrown away, the
Robustness Principle says we should fix this to make both sequence
numbers valid.

The crq is passed in registers and is the same on BE and LE hosts.
However, current implementation allocates a structure on-stack to
represent the crq, initializes the members swapping them to BE, and
loads the structure swapping it from BE. This is pointless and causes
GCC warnings about ununitialized members. Get rid of the structure and

The patch simply replaces all msleep function calls with usleep_range calls
in the generic drivers.
Tested with an Infineon TPM 1.2, using the generic tpm-tis module, for a
thousand PCR extends, we see results going from 1m57s unpatched to 40s
with the new patch. We obtain similar results when using the original and
patched tpm_infineon driver, which is also part of the patch.
Similarly with a STM TPM 2.0, using the CRB driver, it takes about 20ms per
extend unpatched and around 7ms with the new patch.
Note that the PCR consistency is untouched with this patch, each TPM has
been tested with 10 million extends and the aggregated PCR value is
continuously verified to be correct.
As an extension of this work, this could potentially and easily be applied
to other vendor's drivers. Still, these changes are not included in the
proposed patch as they are untested.

For inline asm statements which have a CALL instruction, we list the
stack pointer as a constraint to convince GCC to ensure the frame
pointer is set up first:
static inline void foo()
{
register void *__sp asm(_ASM_SP);
asm("call bar" : "+r" (__sp))
}
Unfortunately, that pattern causes Clang to corrupt the stack pointer.
The fix is easy: convert the stack pointer register variable to a global
variable.
It should be noted that the end result is different based on the GCC
version. With GCC 6.4, this patch has exactly the same result as
before:
defconfig defconfig-nofp distro distro-nofp
before 9820389 9491555 8816046 8516940
after 9820389 9491555 8816046 8516940
With GCC 7.2, however, GCC's behavior has changed. It now changes its
behavior based on the conversion of the register variable to a global.
That somehow convinces it to *always* set up the frame pointer before
inserting *any* inline asm. (Therefore, listing the variable as an
output constraint is a no-op and is no longer necessary.) It's a bit
overkill, but the performance impact should be negligible. And in fact,
there's a nice improvement with frame pointers disabled:
defconfig defconfig-nofp distro distro-nofp
before 9796316 9468236 9076191 8790305
after 9796957 9464267 9076381 8785949
So in summary, while listing the stack pointer as an output constraint
is no longer necessary for newer versions of GCC, it's still needed for
older versions.

The kbuild bot reported the following warning with GCC 4.4 and a
randconfig:
net/socket.o: warning: objtool: compat_sock_ioctl()+0x1083: stack state mismatch: cfa1=7+160 cfa2=-1+0
This is caused by another GCC non-optimization, where it backs up and
restores the stack pointer for no apparent reason:
2f91: 48 89 e0 mov %rsp,%rax
2f94: 4c 89 e7 mov %r12,%rdi
2f97: 4c 89 f6 mov %r14,%rsi
2f9a: ba 20 00 00 00 mov $0x20,%edx
2f9f: 48 89 c4 mov %rax,%rsp
This issue would have been happily ignored before the following commit:
dd88a0a0c861 ("objtool: Handle GCC stack pointer adjustment bug")
But now that objtool is paying attention to such stack pointer writes
to/from a register, it needs to understand them properly. In this case
that means recognizing that the "mov %rsp, %rax" instruction is
potentially a backup of the stack pointer.
