The arm, mips and powerpc builds failed on the stable-rc 5.15.197-rc1.

Build regressions: arm, fuse-tegra30.c:250:10: error: 'const struct
tegra_fuse_soc' has no member named 'cells'
Build regressions: arm, fuse-tegra30.c:250:18: error: initialization
of 'const struct attribute_group *' from incompatible pointer type
'const struct nvmem_cell_info *' [-Werror=incompatible-pointer-types]
Build regressions: arm, fuse-tegra30.c:251:10: error: 'const struct
tegra_fuse_soc' has no member named 'num_cells'

Build regressions: mips, tlb-r4k.c:591:31: error: passing argument 1
of 'memblock_free' makes integer from pointer without a cast
[-Werror=int-conversion]

Build regressions: powerpc, mm/mempool.c:68:17: error: 'for' loop
initial declarations are only allowed in C99 or C11 mode

Reported-by: Linux Kernel Functional Testing <lkft@...aro.org>

ARM build regressions are due to,

  soc/tegra: fuse: Add Tegra114 nvmem cells and fuse lookups
  [ Upstream commit b9c01adedf38c69abb725a60a05305ef70dbce03 ]

MIPS build regressions are due to,

  MIPS: mm: kmalloc tlb_vpn array to avoid stack overflow
  commit 841ecc979b18d3227fad5e2d6a1e6f92688776b5 upstream.

Powerpc build regressions are due to,

  mm/mempool: replace kmap_atomic() with kmap_local_page()
  [ Upstream commit f2bcc99a5e901a13b754648d1dbab60f4adf9375 ]
