ktest fails if meta characters are in GRUB_MENU, for example
GRUB_MENU = 'Fedora (test)'
The failure happens because the meta characters are not escaped,
so the menu doesn't match in any entries in GRUB_FILE.
Use quotemeta() to escape the meta characters.

If a test has an error, display not only the what type of test failed, but
if the test was giving a name, display that too, as well as the current
iteration of the tests. Each test has an iteration number associated to it.
For error messages display that iteration number along with the test type
and test name. This includes the message that gets sent via email.

Currently, when a new resource group is created, the allocation values
of the MBA resource are not initialized and remain meaningless data.
For example:
mkdir /sys/fs/resctrl/p1
cat /sys/fs/resctrl/p1/schemata
MB:0=100;1=100
echo "MB:0=10;1=20" > /sys/fs/resctrl/p1/schemata
cat /sys/fs/resctrl/p1/schemata
MB:0= 10;1= 20
rmdir /sys/fs/resctrl/p1
mkdir /sys/fs/resctrl/p2
cat /sys/fs/resctrl/p2/schemata
MB:0= 10;1= 20
Therefore, when the new group is created, it is reasonable to initialize
MBA resource with default values.
Initialize the MBA resource and cache resources in separate functions.

The get_secureboot_mode() function unnecessarily requires both
CONFIG_EFIVAR_FS and CONFIG_EFI_VARS to be enabled to determine if the
system is booted in secure boot mode. On some systems the old EFI
variable support is not enabled or, possibly, even implemented.
This patch first checks the efivars filesystem for the SecureBoot and
SetupMode flags, but falls back to using the old EFI variable support.
The "secure_boot_file" and "setup_mode_file" couldn't be quoted due to
globbing. This patch also removes the globbing.

Keeping track of the number of mitigations for all the CPU speculation
bugs has become overwhelming for many users. It's getting more and more
complicated to decide which mitigations are needed for a given
architecture. Complicating matters is the fact that each arch tends to
have its own custom way to mitigate the same vulnerability.
Most users fall into a few basic categories:
a) they want all mitigations off;
b) they want all reasonable mitigations on, with SMT enabled even if
it's vulnerable; or
c) they want all reasonable mitigations on, with SMT disabled if
vulnerable.
Define a set of curated, arch-independent options, each of which is an
aggregation of existing options:
- mitigations=off: Disable all mitigations.
- mitigations=auto: [default] Enable all the default mitigations, but
leave SMT enabled, even if it's vulnerable.
- mitigations=auto,nosmt: Enable all the default mitigations, disabling
SMT if needed by a mitigation.
Currently, these options are placeholders which don't actually do
anything. They will be fleshed out in upcoming patches.

This is a leftover from when the rings initially were not free flowing,
and hence a test for tail + 1 == head would indicate full. Since we now
let them wrap instead of mask them with the size, we need to check if
they drift more than the ring size from each other.
This fixes a case where we'd overwrite CQ ring entries, if the user
failed to reap completions. Both cases would ultimately result in lost
completions as the application violated the depth it asked for. The only
difference is that before this fix we'd return invalid entries for the
overflowed completions, instead of properly flagging it in the
cq_ring->overflow variable.

Current perf_evlist__poll_thread() code could finish without draining
the data. Adding the logic that makes sure we won't finish before the
drain.

As reported by Jiri Olsa in:
"[BUG] perf: intel_pt won't display kernel function"
https://lore.kernel.org/lkml/20190403143738.GB32001@krava
Recent changes to support PERF_RECORD_KSYMBOL and PERF_RECORD_BPF_EVENT
broke --kallsyms option. This is because it broke test __map__is_kmodule.
This patch fixes this by adding check for bpf program, so that these maps
are not mistaken as kernel modules.
