Pull x86 iopl updates from Ingo Molnar:
"This implements a nice simplification of the iopl and ioperm code that
Thomas Gleixner discovered: we can implement the IO privilege features
of the iopl system call by using the IO permission bitmap in
permissive mode, while trapping CLI/STI/POPF/PUSHF uses in user-space
if they change the interrupt flag.
This implements that feature, with testing facilities and related
cleanups"
[ "Simplification" may be an over-statement. The main goal is to avoid
the cli/sti of iopl by effectively implementing the IO port access
parts of iopl in terms of ioperm.
This may end up not workign well in case people actually depend on
cli/sti being available, or if there are mixed uses of iopl and
ioperm. We will see.. - Linus ]

When a driver enables MSI-X, msix_program_entries() reads the MSI-X Vector
Control register for each vector and saves it in desc->masked. Each
register is 32 bits and bit 0 is the actual Mask bit.
When we restored these registers during resume, we previously set the Mask
bit if *any* bit in desc->masked was set instead of when the Mask bit
itself was set:
pci_restore_state
pci_restore_msi_state
__pci_restore_msix_state
for_each_pci_msi_entry
msix_mask_irq(entry, entry->masked) <-- entire u32 word
__pci_msix_desc_mask_irq(desc, flag)
mask_bits = desc->masked & ~PCI_MSIX_ENTRY_CTRL_MASKBIT
if (flag) <-- testing entire u32, not just bit 0
mask_bits |= PCI_MSIX_ENTRY_CTRL_MASKBIT
writel(mask_bits, desc_addr + PCI_MSIX_ENTRY_VECTOR_CTRL)
This means that after resume, MSI-X vectors were masked when they shouldn't
be, which leads to timeouts like this:
nvme nvme0: I/O 978 QID 3 timeout, completion polled
On resume, set the Mask bit only when the saved Mask bit from suspend was
set.
This should remove the need for 19ea025e1d28 ("nvme: Add quirk for Kingston
NVME SSD running FW E8FK11.T").

27e20603c54b ("PCI/MSI: Move D0 check into pci_msi_check_device()")
moved the power state check into pci_msi_check_device(), which was
subsequently renamed to pci_msi_supported(). This didn't change the
behavior, since both callers checked the power state.
However, it doesn't fit the current "pci_msi_supported()" name, which
should return what the device is capable of, independent of the power
state.
Move the power state check back into the callers for readability. No
functional change intended.

This system call has been deprecated almost since it was introduced, and
in a survey of the linux distributions I can no longer find any of them
that enable CONFIG_SYSCTL_SYSCALL. The only indication that I can find
that anyone might care is that a few of the defconfigs in the kernel
enable CONFIG_SYSCTL_SYSCALL. However this appears in only 31 of 414
defconfigs in the kernel, so I suspect this symbols presence is simply
because it is harmless to include rather than because it is necessary.
As there appear to be no users of the sysctl system call, remove the
code. As this removes one of the few uses of the internal kernel mount
of proc I hope this allows for even more simplifications of the proc
filesystem.

"The main changes in this cycle were:
- Cross-arch changes to move the linker sections for NOTES and
EXCEPTION_TABLE into the RO_DATA area, where they belong on most
architectures. (Kees Cook)
- Switch the x86 linker fill byte from x90 (NOP) to 0xcc (INT3), to
trap jumps into the middle of those padding areas instead of
sliding execution. (Kees Cook)
- A thorough cleanup of symbol definitions within x86 assembler code.
The rather randomly named macros got streamlined around a
(hopefully) straightforward naming scheme:
SYM_START(name, linkage, align...)
SYM_END(name, sym_type)
SYM_FUNC_START(name)
SYM_FUNC_END(name)
SYM_CODE_START(name)

The 'start' variable indicates the start of a filemap and is set to the
iocb's position, which we have already cached as 'pos', upon function
entry.
'pos' is used as a cursor indicating the current position and updated
later in iomap_dio_rw(), but not before the last use of 'start'.
Remove 'start' as it's synonym for 'pos' before we're entering the loop
calling iomapp_apply().

iomap_dio_bio_actor() copies iter to a local variable and then limits it
to a file extent we have mapped. When IO is submitted,
iomap_dio_bio_actor() advances the original iter while the copied iter
is advanced inside bio_iov_iter_get_pages(). This logic is non-obvious
especially because both iters still point to same shared structures
(such as pipe info) so if iov_iter_advance() changes anything in the
shared structure, this scheme breaks. Let's just truncate and reexpand
the original iter as needed instead of playing games with copying iters
and keeping them in sync.

Currently we support only static linking with kernel's libbpf
(tools/lib/bpf). This patch adds libbpf package detection and support to
link perf with it dynamically.
The libbpf package status is displayed with:
$ make VF=1
Auto-detecting system features:
...
... libbpf: [ on ]
It's not checked by default, because it's quite new. Once it's on most
distros we can switch it on.
For the same reason it's not added to the test-all check.
Perf does not need advanced version of libbpf, so we can check just for
the base bpf_object__open function.
Adding new compile variable to detect libbpf package and link bpf
dynamically:
$ make LIBBPF_DYNAMIC=1
...
LINK perf
$ ldd perf | grep bpf
libbpf.so.0 => /lib64/libbpf.so.0 (0x00007f46818bc000)
If libbpf is not installed, build stops with:

And pick the shortest name: 'struct maps'.
The split existed because we used to have two groups of maps, one for
functions and one for variables, but that only complicated things,
sometimes we needed to figure out what was at some address and then had
to first try it on the functions group and if that failed, fall back to
the variables one.
That split is long gone, so for quite a while we had only one struct
maps per struct map_groups, simplify things by combining those structs.
First patch is the minimum needed to merge both, follow up patches will
rename 'thread->mg' to 'thread->maps', etc.

With the recent 59bb47985c1d ("mm, sl[aou]b: guarantee natural
alignment for kmalloc(power-of-two)"), kzalloc() is able to allocate
a 4KB buffer that is guaranteed to be 4KB-aligned. Here the size and
alignment of hbus is important because hbus's field
retarget_msi_interrupt_params must not cross a 4KB page boundary.
Here we prefer kzalloc to get_zeroed_page(), because a buffer
allocated by the latter is not tracked and scanned by kmemleak, and
hence kmemleak reports the pointer contained in the hbus buffer
(i.e. the hpdev struct, which is created in new_pcichild_device() and
is tracked by hbus->children) as memory leak (false positive).
If the kernel doesn't have 59bb47985c1d, get_zeroed_page() *must* be
used to allocate the hbus buffer and we can avoid the kmemleak false
positive by using kmemleak_alloc() and kmemleak_free() to ask
kmemleak to track and scan the hbus buffer.

A VM can have multiple Hyper-V hbus. It's incorrect to set the global
variable 'pci_protocol_version' when *every* hbus is initialized in
hv_pci_protocol_negotiation(). This is not an issue in practice since
every hbus should have the same value of hbus->protocol_version, but
we should make the variable per-hbus, so in case we have busses
with different protocol versions, the driver can still work correctly.

Add suspend() and resume() functions so that Hyper-V virtual PCI devices
are handled properly when the VM hibernates and resumes from
hibernation.
Note that the suspend() function must make sure there are no pending
work items before calling vmbus_close(), since it runs in a process
context as a callback in dpm_suspend(). When it starts to run, the
channel callback hv_pci_onchannelcallback(), which runs in a tasklet
context, can be still running concurrently and scheduling new work items
onto hbus->wq in hv_pci_devices_present() and hv_pci_eject_device(), and
the work item handlers can access the vmbus channel, which can be being
closed by hv_pci_suspend(), e.g. the work item handler
pci_devices_present_work() -> new_pcichild_device() writes to the vmbus
channel.
To eliminate the race, hv_pci_suspend() disables the channel callback
tasklet, sets hbus->state to hv_pcibus_removing, and re-enables the
tasklet. This way, when hv_pci_suspend() proceeds, it knows that no new
work item can be scheduled, and then it flushes hbus->wq and safely
closes the vmbus channel.
