gmp-6.3.0-160000.2.2

- Manually select the z13/z14 architecture level specific assembly routines
  for s390x and SLFO since GMP lacks fat binary support there and also lacks
  a way to auto-detect the architecture level used at compile-time.
  [jsc#PED-3270]

- Use %patch -P N instead of deprecated %patchN.

- Add gmp-6.3.0-s390x-fix.patch to fix s390x optimized code on z13.

- GMP 6.3.0
  * A possible overflow of type int is avoided for mpz_cmp on huge operands.
  * A possible error condition when a malformed file is read with mpz_inp_raw
    is now correctly handled.
  * New public function mpz_prevprime, companion of the existing mpz_nextprime.
  * New documented pointer types mpz_ptr, mpz_srcptr, and similar for other
    GMP types. Refer to the manual for full list and suggested usage. These
    types have been present in gmp.h at least since GMP-4.0, but previously
    not advertised to users.
  * Support for 64-bit Arm under Macos.
  * Support for the loongarch64 CPU family.
  * Support for building with LTO, link-time optimisations.
  * New special code for base = 2 in mpz_powm reduces the average time for
    the functions that test primality.
  * Speedup for the function mpz_nextprime on large operands.
  * Speedup for multiplications (some sizes only) thanks to new internal
    functions to compute small negacyclic products.
  * Special assembly code for IBM z13 and later "mainframe" CPUs, resulting
    in a huge speedup.
  * Improved assembly for several 64-bit x86 CPUs, Risc-V, 64-bit Arm.
- Removed gmp-6.2.1-CVE-2021-43618.patch which is included in the
  new release.

- Add gmp-6.2.1-CVE-2021-43618.patch to fix buffer overflow on
  malformed input to mpz_inp_raw.  [bsc#1192717, CVE-2021-43618]

- Compute FIPS hmac for libgmp.so.10 [bsc#1184555]

- do not break SLE 12 build when applying spec-cleaner

- Add gmp-6.2.1-arm64-invert_limb.patch [bsc#1179751]

- GMP 6.2.1:
  * A possible overflow of type int is avoided for mpz_cmp on huge
    operands
  * Overflows are more carefully detected and reported for
    mpz_pow_ui
  * Fix a bug in longlong.h for aarch64 sub_ddmmss
  * mini-gmp: mpz_out_str and mpq_out_str now correctly handle out
    of range bases
  * C90 compliance
  * Support for more processors

- correct license statement (library itself is no GPL-3.0)
