asm-generic: Unify uapi bitsperlong.h for arm64, riscv and loongarch

2023-06-22T15:04:36+00:00

Now we specify the minimal version of GCC as 5.1 and Clang/LLVM as 11.0.0
in Documentation/process/changes.rst, __CHAR_BIT__ and __SIZEOF_LONG__ are
usable, it is probably fine to unify the definition of __BITS_PER_LONG as
(__CHAR_BIT__ * __SIZEOF_LONG__) in asm-generic uapi bitsperlong.h.

In order to keep safe and avoid regression, only unify uapi bitsperlong.h
for some archs such as arm64, riscv and loongarch which are using newer
toolchains that have the definitions of __CHAR_BIT__ and __SIZEOF_LONG__.

tools headers kvm: Sync uapi/{asm/linux} kvm.h headers with the kernel sources

2023-03-04T02:24:10+00:00

To pick up the changes in:

  89b0e7de3451a17f ("KVM: arm64: nv: Introduce nested virtualization VCPU feature")
  14329b825ffb7f27 ("KVM: x86/pmu: Introduce masked events to the pmu event filter")

  14329b825ffb7f27 ("KVM: x86/pmu: Introduce masked events to the pmu event filter")

That don't change functionality in tools/perf, as no new ioctl is added
for the 'perf trace' scripts to harvest.

This addresses these perf build warnings:

selftests/bpf: Remove not used headers

2023-02-22T21:01:34+00:00

The following three uapi headers:

    tools/arch/s390/include/uapi/asm/bpf_perf_event.h
    tools/arch/s390/include/uapi/asm/ptrace.h

were introduced in commit 618e165b2a8e ("selftests/bpf: sync kernel headers
and introduce arch support in Makefile"), they are not used any more after
commit 720f228e8d31 ("bpf: fix broken BPF selftest build"), so remove them.
