When running the mincore_selftest on a system with an XFS file system, it
failed the "check_file_mmap" test case due to the read-ahead pages reaching
the end of the file. The failure log is as below:
RUN global.check_file_mmap ...
mincore_selftest.c:264:check_file_mmap:Expected i (1024) < vec_size (1024)
mincore_selftest.c:265:check_file_mmap:Read-ahead pages reached the end of the file
check_file_mmap: Test failed
FAIL global.check_file_mmap
This is because the read-ahead window size of the XFS file system on this
machine is 4 MB, which is larger than the size from the #PF address to the
end of the file. As a result, all the pages for this file are populated.
blockdev --getra /dev/nvme0n1p5
8192
blockdev --getbsz /dev/nvme0n1p5
512
This issue can be fixed by extending the current FILE_SIZE 4MB to a larger
number, but it will still fail if the read-ahead window size of the file
system is larger enough. Additionally, in the real world, read-ahead pages
reaching the end of the file can happen and is an expected behavior.
Therefore, allowing read-ahead pages to reach the end of the file is a
better choice for the "check_file_mmap" test case.

A recent optimization change in LLVM [1] aims to transform certain loop
idioms into calls to strlen() or wcslen(). This change transforms the
first while loop in UniStrcat() into a call to wcslen(), breaking the
build when UniStrcat() gets inlined into alloc_path_with_tree_prefix():
ld.lld: error: undefined symbol: wcslen
>>> referenced by nls_ucs2_utils.h:54 (fs/smb/client/../../nls/nls_ucs2_utils.h:54)
>>> vmlinux.o:(alloc_path_with_tree_prefix)
>>> referenced by nls_ucs2_utils.h:54 (fs/smb/client/../../nls/nls_ucs2_utils.h:54)
>>> vmlinux.o:(alloc_path_with_tree_prefix)
Disable this optimization with '-fno-builtin-wcslen', which prevents the
compiler from assuming that wcslen() is available in the kernel's C
library.
[ More to the point - it's not that we couldn't implement wcslen(), it's
that this isn't an optimization at all in the context of the kernel.
Replacing a simple inlined loop with a function call to the same loop
is just stupid and pointless if you don't have long strings and fancy
libraries with vectorization support etc.
For the regular 'strlen()' cases, we want the compiler to do this in
order to handle the trivial case of constant strings. And we do have
optimized versions of 'strlen()' on some architectures. But for
wcslen? Just no. - Linus ]

When running as a PVH dom0 the ACPI tables exposed to Linux are (mostly)
the native ones, thus exposing the C and P states, that can lead to
attachment of CPU idle and frequency drivers. However the entity in
control of the CPU C and P states is Xen, as dom0 doesn't have a full view
of the system load, neither has all CPUs assigned and identity pinned.
Like it's done for classic PV guests, prevent Linux from using idle or
frequency state drivers when running as a PVH dom0.
On an AMD EPYC 7543P system without this fix a Linux PVH dom0 will keep the
host CPUs spinning at 100% even when dom0 is completely idle, as it's
attempting to use the acpi_idle driver.

Cleanup fprobe address hash table on module unloading because the
target symbols will be disappeared when unloading module and not
sure the same symbol is mapped on the same address.
Note that this is at least disables the fprobes if a part of target
symbols on the unloaded modules. Unlike kprobes, fprobe does not
re-enable the probe point by itself. To do that, the caller should
take care register/unregister fprobe when loading/unloading modules.
This simplifies the fprobe state managememt related to the module
loading/unloading.

The pKVM FF-A proxy rejects FF-A requests other than FFA_VERSION until
version negotiation is complete, which is signalled by setting the
global 'has_version_negotiated' variable.
To avoid excessive locking, this variable is checked directly from
kvm_host_ffa_handler() in response to an FF-A call, but this can race
against another CPU performing the negotiation and potentially lead to
reading a torn value (incredibly unlikely for a 'bool') or problematic
re-ordering of the accesses to 'has_version_negotiated' and
'hyp_ffa_version' whereby a stale version number could be read by
__do_ffa_mem_xfer().
Use acquire/release primitives when writing 'has_version_negotiated'
with the version lock held and when reading without the lock held.

constant fields used by both contextx, followed by a line responsible

PVH dom0 re-uses logic from PV dom0, in which RAM ranges not assigned to
dom0 are re-used as scratch memory to map foreign and grant pages. Such
logic relies on reporting those unpopulated ranges as RAM to Linux, and
mark them as reserved. This way Linux creates the underlying page
structures required for metadata management.
Such approach works fine on PV because the initial balloon target is
calculated using specific Xen data, that doesn't take into account the
memory type changes described above. However on HVM and PVH the initial
balloon target is calculated using get_num_physpages(), and that function
does take into account the unpopulated RAM regions used as scratch space
for remote domain mappings.
This leads to PVH dom0 having an incorrect initial balloon target, which
causes malfunction (excessive memory freeing) of the balloon driver if the
dom0 memory target is later adjusted from the toolstack.
Fix this by using xen_released_pages to account for any pages that are part
of the memory map, but are already unpopulated when the balloon driver is
initialized. This accounts for any regions used for scratch remote
mappings. Note on x86 xen_released_pages definition is moved to
enlighten.c so it's uniformly available for all Xen-enabled builds.
Take the opportunity to unify PV with PVH/HVM guests regarding the usage of
get_num_physpages(), as that avoids having to add different logic for PV vs
PVH in both balloon_add_regions() and arch_xen_unpopulated_init().
Much like a6aa4eb994, the code in this changeset should have been part of
38620fc4e8.

__VA_OPT__ is a macro that is useful when some arguments can be present
or not to entirely skip some part of a definition. Unfortunately, it
is a too recent addition that some of the still supported old GCC
versions do not know about, and is anyway not part of C11 that is the
version used in the kernel.
Find a trick to remove this macro, typically '__VA_ARGS__ + 0' is a
workaround used in netlink.h which works very well here, as we either
expect:
- 0
- A positive value
- No value, which means the field should be 0.
