This allows user space to skip pages that are offline when dumping. This is
especially relevant when dealing with pages that have been unplugged in
the context of virtualization, and their backing storage has already
been freed.

Fix an issue with FIFO Size and burst size.
Fix an incomplete allocator for Hardware descriptors: memory badly
allocated.

Build.include invokes the pre-processor via GCC in order to generate a
dependency list for the input file. Since these options are passed using
'-Wp,-M...,$(depfile)' it is important that $(depfile) does not contain
any commas, so these are substituted with underscores. This substitution
will break

Both buffer Transfer Length (TLEN if any) and transfer size have to be

The bpf-script-test-kbuild.c script, used in one of the LLVM subtests,
includes ptrace.h unnecessarily, and that ends up making it include a
header that uses asm(_ASM_SP), a feature that is not supported by clang
<= 4.0, breaking that 'perf test' entry.

To be consistent with other HAVE_XXX_SUPPORT uses in Makefile.config,

Fixed a incorrect option and usage to those shown by "perf sched timehist -h",

This reverts commit ca26cffa4e4aaeb09bb9e308f95c7835cb149248.
Newer clang versions accept that asm(_ASM_SP) construct, and now that
the bpf-script-test-kbuild.c script, used in one of the 'perf test LLVM'
subtests doesn't include ptrace.h, which ended up including

When we call ssch, an interrupt might already be pending once we
return from the START SUBCHANNEL instruction. Therefore we need to
make sure interrupts are disabled until after we're done with our

Our userspace defines READ_ONCE() in a way that clang

Currently print count interval for performance counters values is
