This patch introduce a vDPA driver for virtio-pci device. It bridges
the virtio-pci control command to the vDPA bus. This will be used for
features prototyping and testing.
Note that get/restore virtqueue state is not supported which needs
extension on the virtio specification.

The games with 'rm' are on (two separate instances) of a local variable,

Quoting Aditya Pakki:
"I was the author of the patch and it was the cause of the giant UMN
revert.
The patch is garbage and I was unaware of the steps involved in
retracting it. I *believed* the maintainers would pull it, given it
was already under Greg's list. The patch does not introduce any bugs
but is pointless and is stupid. I accept my incompetence and for not
requesting a revert earlier."

No problem on 64-bit, or without huge pages, but xfstests generic/285
and other SEEK_HOLE/SEEK_DATA tests have regressed on huge tmpfs, and on
32-bit architectures, with the new mapping_seek_hole_data(). Several
different bugs turned out to need fixing.
u64 cast to stop losing bits when converting unsigned long to loff_t
(and let's use shifts throughout, rather than mixed with * and /).
Use round_up() when advancing pos, to stop assuming that pos was already
THP-aligned when advancing it by THP-size. (This use of round_up()
assumes that any THP has THP-aligned index: true at present and true
going forward, but could be recoded to avoid the assumption.)
Use xas_set() when iterating away from a THP, so that xa_index stays in
synch with start, instead of drifting away to return bogus offset.
Check start against end to avoid wrapping 32-bit xa_index to 0 (and to
handle these additional cases, seek_data or not, it's easier to break
the loop than goto: so rearrange exit from the function).
[hughd@google.com: remove unneeded u64 casts, per Matthew]

Since commit 0cc3b0ec23 ("Clarify (and fix) in 4.13 MAX_LFS_FILESIZE

In the function auxtrace_parse_snapshot_options(), the callback pointer
"itr->parse_snapshot_options" can be NULL if it has not been set during
the AUX record initialization. This can cause tool crashing if the
callback pointer "itr->parse_snapshot_options" is dereferenced without
performing NULL check.
Add a NULL check for the pointer "itr->parse_snapshot_options" before
invoke the callback.

The only stepping of Broadwell Xeon parts is stepping 1. Fix the
relevant isolation_ucodes[] entry, which previously enumerated
stepping 2.
Although the original commit was characterized as an optimization, it
is also a workaround for a correctness issue.
If a PMI arrives between kvm's call to perf_guest_get_msrs() and the
subsequent VM-entry, a stale value for the IA32_PEBS_ENABLE MSR may be
restored at the next VM-exit. This is because, unbeknownst to kvm, PMI
throttling may clear bits in the IA32_PEBS_ENABLE MSR. CPUs with "PEBS
isolation" don't suffer from this issue, because perf_guest_get_msrs()
doesn't report the IA32_PEBS_ENABLE value.

Commit 941432d007 ("arm64: dts: allwinner: Drop non-removable from
SoPine/LTS SD card") enabled the card detect GPIO for the SOPine module,
along the way with the Pine64-LTS, which share the same base .dtsi.
This was based on the observation that the Pine64-LTS has as "push-push"
SD card socket, and that the schematic mentions the card detect GPIO.
After having received two reports about failing SD card access with that
patch, some more research and polls on that subject revealed that there
are at least two different versions of the Pine64-LTS out there:
- On some boards (including mine) the card detect pin is "stuck" at
high, regardless of an microSD card being inserted or not.
- On other boards the card-detect is working, but is active-high, by
virtue of an explicit inverter circuit, as shown in the schematic.
To cover all versions of the board out there, and don't take any chances,
let's revert the introduction of the active-low CD GPIO, but let's use
the broken-cd property for the Pine64-LTS this time. That should avoid
regressions and should work for everyone, even allowing SD card changes
now.
The SOPine card detect has proven to be working, so let's keep that
GPIO in place.

As we are using cpu_pm to save and restore context, we must also save and
restore the GPIO sysconfig register. This is needed because we are not
calling PM runtime functions at all with cpu_pm.
We need to save the sysconfig on idle as it's value can get reconfigured by
PM runtime and can be different from the init time value. Device specific
flags like "ti,no-idle-on-init" can affect the init value.

There may be a kernel panic on the Haswell server and the Broadwell
server, if the snbep_pci2phy_map_init() return error.
The uncore_extra_pci_dev[HSWEP_PCI_PCU_3] is used in the cpu_init() to
detect the existence of the SBOX, which is a MSR type of PMON unit.
The uncore_extra_pci_dev is allocated in the uncore_pci_init(). If the
snbep_pci2phy_map_init() returns error, perf doesn't initialize the
PCI type of the PMON units, so the uncore_extra_pci_dev will not be
allocated. But perf may continue initializing the MSR type of PMON
units. A null dereference kernel panic will be triggered.
The sockets in a Haswell server or a Broadwell server are identical.
Only need to detect the existence of the SBOX once.
Current perf probes all available PCU devices and stores them into the
uncore_extra_pci_dev. It's unnecessary.
Use the pci_get_device() to replace the uncore_extra_pci_dev. Only
detect the existence of the SBOX on the first available PCU device once.
Factor out hswep_has_limit_sbox(), since the Haswell server and the
Broadwell server uses the same way to detect the existence of the SBOX.
Add some macros to replace the magic number.

Masami added a wrapper to be able to unhash trace event pointers
as they are only read by root anyway, and they can also be extracted
by the raw trace data buffers. But this wrapper utilized the iterator
to have a temporary buffer to manipulate the text with.
tp_printk is a kernel command line option that will send the trace
output of a trace event to the console on boot up (useful when the
system crashes before finishing the boot). But the code used the same
wrapper that Masami added, and its iterator did not have a buffer,
and this caused the system to crash.
Have the wrapper just print the trace event normally if the iterator
has no temporary buffer.

cap_setfcap is required to create file capabilities.
Since commit 8db6c34f1d ("Introduce v3 namespaced file capabilities"),
a process running as uid 0 but without cap_setfcap is able to work
around this as follows: unshare a new user namespace which maps parent
uid 0 into the child namespace.
While this task will not have new capabilities against the parent
namespace, there is a loophole due to the way namespaced file
capabilities are represented as xattrs. File capabilities valid in
userns 1 are distinguished from file capabilities valid in userns 2 by
the kuid which underlies uid 0. Therefore the restricted root process
can unshare a new self-mapping namespace, add a namespaced file
capability onto a file, then use that file capability in the parent
namespace.
To prevent that, do not allow mapping parent uid 0 if the process which
opened the uid_map file does not have CAP_SETFCAP, which is the
capability for setting file capabilities.
As a further wrinkle: a task can unshare its user namespace, then open
its uid_map file itself, and map (only) its own uid. In this case we do
not have the credential from before unshare, which was potentially more
restricted. So, when creating a user namespace, we record whether the
creator had CAP_SETFCAP. Then we can use that during map_write().
With this patch:
1. Unprivileged user can still unshare -Ur
ubuntu@caps:~$ unshare -Ur
root@caps:~# logout
2. Root user can still unshare -Ur
ubuntu@caps:~$ sudo bash
root@caps:/home/ubuntu# unshare -Ur
root@caps:/home/ubuntu# logout
3. Root user without CAP_SETFCAP cannot unshare -Ur:
root@caps:/home/ubuntu# /sbin/capsh --drop=cap_setfcap --
root@caps:/home/ubuntu# /sbin/setcap cap_setfcap=p /sbin/setcap
unable to set CAP_SETFCAP effective capability: Operation not permitted
root@caps:/home/ubuntu# unshare -Ur
unshare: write failed /proc/self/uid_map: Operation not permitted
Note: an alternative solution would be to allow uid 0 mappings by
processes without CAP_SETFCAP, but to prevent such a namespace from
writing any file capabilities. This approach can be seen at [1].
Background history: commit 95ebabde38 ("capabilities: Don't allow
writing ambiguous v3 file capabilities") tried to fix the issue by
preventing v3 fscaps to be written to disk when the root uid would map
to the same uid in nested user namespaces. This led to regressions for
various workloads. For example, see [2]. Ultimately this is a valid
use-case we have to support meaning we had to revert this change in
3b0c2d3eaa ("Revert 95ebabde38 ("capabilities: Don't allow writing
ambiguous v3 file capabilities")").

Commit in Fixes: added support for kexec-ing a kernel on panic using a
new system call. As part of it, it does prepare a memory map for the new
kernel.
However, while doing so, it wrongly accesses memory it has not
allocated: it accesses the first element of the cmem->ranges[] array in
memmap_exclude_ranges() but it has not allocated the memory for it in
crash_setup_memmap_entries(). As KASAN reports:
BUG: KASAN: vmalloc-out-of-bounds in crash_setup_memmap_entries+0x17e/0x3a0

Make sure the ranges array becomes a single element allocated.
