hexagon: use new system call table

2024-07-10T12:23:38+00:00

The uapi/asm/unistd_32.h and asm/syscall_table_32.h headers can now be
generated from scripts/syscall.tbl, which makes this consistent with
the other architectures that have their own syscall.tbl.

The time32, stat64, rlimit and renameat entries in the syscall_abis_32
line are for system calls that were part of the generic ABI when
arch/hexagon got added but are no longer enabled by default for new
architectures.

As a side-effect, calling an unimplemented syscall now return -ENOSYS
rather than branching into a NULL pointer.

kbuild: force all architectures except um to include mandatory-y

2019-03-17T03:56:32+00:00

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.

arch: unexport asm/shmparam.h for all architectures

2019-02-01T23:46:22+00:00

Most architectures do not export shmparam.h to user-space.

  $ find arch -name shmparam.h  | sort
  arch/alpha/include/asm/shmparam.h
  arch/arc/include/asm/shmparam.h
  arch/arm64/include/asm/shmparam.h
  arch/arm/include/asm/shmparam.h
  arch/csky/include/asm/shmparam.h
  arch/ia64/include/asm/shmparam.h
  arch/mips/include/asm/shmparam.h
  arch/nds32/include/asm/shmparam.h
  arch/nios2/include/asm/shmparam.h
  arch/parisc/include/asm/shmparam.h
  arch/powerpc/include/asm/shmparam.h
  arch/s390/include/asm/shmparam.h
  arch/sh/include/asm/shmparam.h
  arch/sparc/include/asm/shmparam.h
  arch/x86/include/asm/shmparam.h
  arch/xtensa/include/asm/shmparam.h

Strangely, some users of the asm-generic wrapper export shmparam.h

  $ git grep 'generic-y += shmparam.h'
  arch/c6x/include/uapi/asm/Kbuild:generic-y += shmparam.h
  arch/h8300/include/uapi/asm/Kbuild:generic-y += shmparam.h
  arch/hexagon/include/uapi/asm/Kbuild:generic-y += shmparam.h
  arch/m68k/include/uapi/asm/Kbuild:generic-y += shmparam.h
  arch/microblaze/include/uapi/asm/Kbuild:generic-y += shmparam.h
  arch/openrisc/include/uapi/asm/Kbuild:generic-y += shmparam.h
  arch/riscv/include/asm/Kbuild:generic-y += shmparam.h
  arch/unicore32/include/uapi/asm/Kbuild:generic-y += shmparam.h

The newly added riscv correctly creates the asm-generic wrapper
in the kernel space, but the others (c6x, h8300, hexagon, m68k,
microblaze, openrisc, unicore32) create the one in the uapi directory.

Digging into the git history, now I guess fcc8487d477a ("uapi:
export all headers under uapi directories") was the misconversion.
Prior to that commit, no architecture exported to shmparam.h
As its commit description said, that commit exported shmparam.h
for c6x, h8300, hexagon, m68k, openrisc, unicore32.

83f0124ad81e ("microblaze: remove asm-generic wrapper headers")
accidentally exported shmparam.h for microblaze.

This commit unexports shmparam.h for those architectures.

There is no more reason to export include/uapi/asm-generic/shmparam.h,
so it has been moved to include/asm-generic/shmparam.h

arch: restore generic-y += shmparam.h for some architectures

2019-01-07T02:16:11+00:00

For some reasons, I accidentally got rid of "generic-y += shmparam.h"
from some architectures.

Restore them to fix building c6x, h8300, hexagon, m68k, microblaze,
openrisc, and unicore32.

arch: remove redundant UAPI generic-y defines

2019-01-06T01:22:15+00:00

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.

arch: remove stale comments "UAPI Header export list"

2019-01-06T00:46:51+00:00

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.

bpf: correct broken uapi for BPF_PROG_TYPE_PERF_EVENT program type

2017-12-05T14:02:40+00:00

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.

hexagon: move generic-y of exported headers to uapi/asm/Kbuild

2017-07-09T18:43:26+00:00

Since commit fcc8487d477a ("uapi: export all headers under uapi
directories"), all (and only) headers under uapi directories are
exported, but asm-generic wrappers are still exceptions.

To complete de-coupling the uapi from kernel headers, move generic-y
of exported headers to uapi/asm/Kbuild.

With this change, "make headers_install" will just need to parse
uapi/asm/Kbuild to build up exported headers.

Also, move "generic-y += kprobes.h" up in order to keep the entries
sorted.

signal: Remove non-uapi

2017-06-04T13:11:47+00:00

By moving the kernel side __SI_* defintions right next to the userspace
ones we can kill the non-uapi versions of  include
include/asm-generic/siginfo.h and untangle the unholy mess of includes.
