With preemption it is not enough to track the current_ctx_seqno globally
as execution might switch between rings.
This is especially problematic when current_ctx_seqno is used to
determine whether a page table switch is necessary as it might lead to
security bugs.
Track current context per ring.

The header, security/selinux/include/classmap.h, is included not only
from kernel space but also from host programs.
It includes <linux/capability.h> and <linux/socket.h>, which pull in
more <linux/*.h> headers. This makes the host programs less portable,
specifically causing build errors on macOS.
Those headers are included for the following purposes:
- <linux/capability.h> for checking CAP_LAST_CAP
- <linux/socket.h> for checking PF_MAX
These checks can be guarded by __KERNEL__ so they are skipped when
building host programs. Testing them when building the kernel should
be sufficient.
The header, security/selinux/include/initial_sid_to_string.h, includes
<linux/stddef.h> for the NULL definition, but this is not portable
either. Instead, <stddef.h> should be included for host programs.

In `gpiod_get_label()`, it is possible that `srcu_dereference_check()` may
return a NULL pointer, leading to a scenario where `label->str` is accessed
without verifying if `label` itself is NULL.
This patch adds a proper NULL check for `label` before accessing
`label->str`. The check for `label->str != NULL` is removed because
`label->str` can never be NULL if `label` is not NULL.
This fixes the issue where the label name was being printed as `(efault)`
when dumping the sysfs GPIO file when `label == NULL`.

Oliver reports that the kvm_has_feat() helper is not behaviing as
expected for negative feature. On investigation, the main issue
seems to be caused by the following construct:
#define get_idreg_field(kvm, id, fld) \
(id##_##fld##_SIGNED ? \
get_idreg_field_signed(kvm, id, fld) : \
get_idreg_field_unsigned(kvm, id, fld))
where one side of the expression evaluates as something signed,
and the other as something unsigned. In retrospect, this is totally
braindead, as the compiler converts this into an unsigned expression.
When compared to something that is 0, the test is simply elided.
Epic fail. Similar issue exists in the expand_field_sign() macro.
The correct way to handle this is to chose between signed and unsigned
comparisons, so that both sides of the ternary expression are of the
same type (bool).
In order to keep the code readable (sort of), we introduce new
comparison primitives taking an operator as a parameter, and
rewrite the kvm_has_feat*() helpers in terms of these primitives.

NFS-style symlinks have target location always stored in NFS/UNIX form
where backslash means the real UNIX backslash and not the SMB path
separator.
So do not mangle slash and backslash content of NFS-style symlink during
readlink() syscall as it is already in the correct Linux form.
This fixes interoperability of NFS-style symlinks with backslashes created
by Linux NFS3 client throw Windows NFS server and retrieved by Linux SMB
client throw Windows SMB server, where both Windows servers exports the
same directory.

ReparseDataLength is sum of the InodeType size and DataBuffer size.
So to get DataBuffer size it is needed to subtract InodeType's size from
ReparseDataLength.
Function cifs_strndup_from_utf16() is currentlly accessing buf->DataBuffer
at position after the end of the buffer because it does not subtract
InodeType size from the length. Fix this problem and correctly subtract
variable len.
Member InodeType is present only when reparse buffer is large enough. Check
for ReparseDataLength before accessing InodeType to prevent another invalid
memory access.
Major and minor rdev values are present also only when reparse buffer is
large enough. Check for reparse buffer size before calling reparse_mkdev().

Test "Setup struct perf_event_attr" consists of multiple test cases that
can affect the max sample rate value for perf events. Some test cases
check this value as it should not be lowered under the set minimum for
the given test. Currently, it is possible for the test cases to affect
each other as the previous tests can lower the sample rate, leading to
a possible failure of some of the future test cases as the value is not
restored at any point.

<linux/percpu.h> include was removed from <linux/prandom.h>
in d9f29deb7f ("prandom: Remove unused include") because
this inclusion broke arm64 due to a circular dependency
on include files.
__percpu tag is defined in include/linux/compiler_types.h, so there
is currently no direct need for the inclusion of <linux/percpu.h>.
However, in [1] we would like to repurpose __percpu tag as a named
address space qualifier, where __percpu macro uses defines from
<linux/percpu.h>.
The circular dependency was removed in ddd8e37ebaa1 ("random: Do not
include <linux/prandom.h> in <linux/random.h>") and it cleared
the path for the inclusion of <linux/percpu.h> in <linux/prandom.h>.
This patch is basically a revert of d9f29deb7f
("prandom: Remove unused include").
