unistd_nr_{n32,n64,o32}.h are needed only by include/asm/unistd.h,
which is a kernel-side header file, and their contents is generally
not for userland use.
Move their target destination from include/generated/uapi/asm/ to
include/generated/asm/ to disable exporting them as UAPI headers.

paravirt machine was introduced for Cavium's partial virtualization
technology, however, it's host side support and QEMU support never
landed in upstream.
As Cavium was acquired by Marvel and they have no intention to maintain
their MIPS product line, also paravirt is unlikely to be utilized by
community users, it's time to retire it if nobody steps in to maintain
it.

Currently, every arch/*/include/uapi/asm/Kbuild explicitly includes
the common Kbuild.asm file. Factor out the duplicated include directives
to scripts/Makefile.asm-generic so that no architecture would opt out
of the mandatory-y mechanism.
um is not forced to include mandatory-y since it is a very exceptional
case which does not support UAPI.

Now that Kbuild automatically creates asm-generic wrappers for missing
mandatory headers, it is redundant to list the same headers in
generic-y and mandatory-y.

These comments are leftovers of commit fcc8487d477a ("uapi: export all
headers under uapi directories").
Prior to that commit, exported headers must be explicitly added to
header-y. Now, all headers under the uapi/ directories are exported.

System call table generation script must be run to gener-
ate unistd_(nr_)n64/n32/o32.h and syscall_table_32_o32/
64_n64/64_n32/64-o32.h files. This patch will have changes
which will invokes the script.
This patch will generate unistd_(nr_)n64/n32/o32.h and
syscall_table_32_o32/64_n64/64-n32/64-o32.h files by the
syscall table generation script invoked by parisc/Make-
file and the generated files against the removed files
must be identical.
The generated uapi header file will be included in uapi/-
asm/unistd.h and generated system call table header file
will be included by kernel/scall32-o32/64-n64/64-n32/-
64-o32.Sfile.

Commit 0515e5999a466dfe ("bpf: introduce BPF_PROG_TYPE_PERF_EVENT
program type") introduced the bpf_perf_event_data structure which
exports the pt_regs structure. This is OK for multiple architectures
but fail for s390 and arm64 which do not export pt_regs. Programs
using them, for example, the bpf selftest fail to compile on these
architectures.
For s390, exporting the pt_regs is not an option because s390 wants
to allow changes to it. For arm64, there is a user_pt_regs structure
that covers parts of the pt_regs structure for use by user space.
To solve the broken uapi for s390 and arm64, introduce an abstract
type for pt_regs and add an asm/bpf_perf_event.h file that concretes
the type. An asm-generic header file covers the architectures that
export pt_regs today.
The arch-specific enablement for s390 and arm64 follows in separate
commits.

Regularly, when a new header is created in include/uapi/, the developer
forgets to add it in the corresponding Kbuild file. This error is usually
detected after the release is out.
In fact, all headers under uapi directories should be exported, thus it's
useless to have an exhaustive list.
After this patch, the following files, which were not exported, are now
exported (with make headers_install_all):
asm-arc/kvm_para.h
asm-arc/ucontext.h
asm-blackfin/shmparam.h
asm-blackfin/ucontext.h
asm-c6x/shmparam.h

Note that I have removed from this list the files which are generated in every
exported directories (like .install or .install.cmd).
Thanks to Julien Floret <[email protected]> for the tip to get all
subdirs with a pure makefile command.
For the record, note that exported files for asm directories are a mix of
files listed by:
- include/uapi/asm-generic/Kbuild.asm;
- arch/<arch>/include/uapi/asm/Kbuild;
- arch/<arch>/include/asm/Kbuild.

Add an initial implementation of a proper (i.e. an ELF shared library)
VDSO. With this commit it does not export any symbols, it only replaces
the current signal return trampoline page. A later commit will add user
implementations of gettimeofday()/clock_gettime().
To support both new toolchains and old ones which don't generate ABI
flags section, we define its content manually and then use a tool
(genvdso) to patch up the section to have the correct name and type.
genvdso also extracts symbol offsets ({,rt_}sigreturn) needed by the
kernel, and generates a C file containing a "struct mips_vdso_image"
containing both the VDSO data and these offsets. This C file is
compiled into the kernel.
On 64-bit kernels we require a different VDSO for each supported ABI,
so we may build up to 3 different VDSOs. The VDSO to use is selected by
the mips_abi structure.
A kernel/user shared data page is created and mapped below the VDSO
image. This is currently empty, but will be used by the user time
function implementations which are added later.
[[email protected]:
- Add more comments
- Move abi detection in genvdso.h since it's the get_symbol function
that needs it.
- Add an R6 specific way to calculate the base address of VDSO in order
to avoid the branch instruction which affects performance.
- Do not patch .gnu.attributes since it's not needed for dynamic linking.
- Simplify Makefile a little bit.
- checkpatch fixes
- Restrict VDSO support for binutils < 2.25 for pre-R6
- Include atomic64.h for O32 variant on MIPS64]

Use generic-y and remove headers in arch/mips/include/[uapi/]asm/Kbuild
where the header just includes or is identical to the corresponding
<asm-generic/*.h>.
We can't do the same for uapi/asm/kvm_para.h because it's presence is
explicitly checked in include/uapi/linux/Kbuild to decide whether to add
kvm_para.h to header-y.
