The tools/lib includes fixes break LIBTRACEVENT_DYNAMIC as the makefile
erroneously had dependencies on building libtraceevent even when not
linking with it. This change fixes the issues with LIBTRACEEVENT_DYNAMIC
by making the built files optional.

The datasym workload is to check if perf mem command gets the data
addresses precisely.  This is needed for data symbol test.

  $ perf test -w datasym

I had to keep the buf1 in the data section, otherwise it could end
up in the BSS and was mmaped as a separate //anon region, then it
was not symbolized at all.  It needs to be fixed separately.

Committer notes:

Add a -U _FORTIFY_SOURCE to the datasym CFLAGS, as the main perf flags
set it and it requires building with optimization, and this new test has
a -O0.

The brstack is to run different kinds of branches repeatedly.  This is

The sqrtloop creates a child process to run an infinite loop calling
sqrt() with rand().  This is needed for ARM SPE fork test.

  $ perf test -w sqrtloop

It can take an optional argument to specify how long it will run in
seconds (default: 1).

Committer notes:

Explicitely ignored the sqrt() return to fix the build on systems where
the compiler complains it isn't being used.

And added a sqrtloop specific CFLAGS to disable optimizations to make
this a bit more robust wrt dead code elimination.

Doing that a -U_FORTIFY_SOURCE needs to be added, as -O0 is incompatible
with it.

The -w/--workload option is to run a simple workload used by testing.
This adds a basic framework to run the workloads and 'noploop' workload
as an example.

  $ perf test -w noploop

The noploop does a loop doing nothing (NOP) for a second by default.
It can have an optional argument to specify the time in seconds.

  cifs: add check for returning value of SMB2_set_info_init

SRS cap is the hardware cap telling if the hardware IOMMU can support
requests seeking supervisor privilege or not. SRE bit in scalable-mode
PASID table entry is treated as Reserved(0) for implementation not
supporting SRS cap.

Checking SRS cap before setting SRE bit can avoid the non-recoverable
fault of "Non-zero reserved field set in PASID Table Entry" caused by
setting SRE bit while there is no SRS cap support. The fault messages
look like below:

 DMAR: DRHD: handling fault status reg 2
 DMAR: [DMA Read NO_PASID] Request device [00:0d.0] fault addr 0x1154e1000
       [fault reason 0x5a]
       SM: Non-zero reserved field set in PASID Table Entry

The A/D bits are preseted for IOVA over first level(FL) usage for both
kernel DMA (i.e, domain typs is IOMMU_DOMAIN_DMA) and user space DMA
usage (i.e., domain type is IOMMU_DOMAIN_UNMANAGED).

Presetting A bit in FL requires to preset the bit in every related paging
entries, including the non-leaf ones. Otherwise, hardware may treat this
as an error. For example, in a case of ECAP_REG.SMPWC==0, DMA faults might
occur with below DMAR fault messages (wrapped for line length) dumped.

 DMAR: DRHD: handling fault status reg 2
 DMAR: [DMA Read NO_PASID] Request device [aa:00.0] fault addr 0x10c3a6000

Pull zonefs fixes from Damien Le Moal:

   zone of device, and that zone is a "runt" zone (smaller than the
   other zone). The current code was failing to properly obtain a zone

 - Remove the unused to_attr() function as it is unused, causing
   compilation warnings with clang.

destroyed by i8042_exit() on module unload.

Since pmd_user_accessible_page() doesn't check if a pmd is leaf, it
decrease file_map_count for a non-leaf pmd comes from collapse_huge_page().
and so trigger BUG_ON() unexpectedly.

Fix this problem by using pmd_leaf() insteal of pmd_present() in
pmd_user_accessible_page(). Moreover, use pud_leaf() for
pud_user_accessible_page() too.
