RISC-V Fixes for 5.12-rc4

I have handful of fixes for 5.12: * A fix to the SBI remote fence numbers for hypervisor fences, which had been transcribed in the wrong order in Linux. These fences are only used with the KVM patches applied. * A whole host of build warnings have been fixed, these should have no functional change. * A fix to init_resources() that prevents an off-by-one error from causing an out-of-bounds array reference. This is manifesting during boot on vexriscv. * A fix to ensure the KASAN mappings are visible before proceeding to use them. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEKzw3R0RoQ7JKlDp6LhMZ81+7GIkFAmBVgV4THHBhbG1lckBk YWJiZWx0LmNvbQAKCRAuExnzX7sYiTOWD/4l+uRCwTelZqm/G0yKSSAevAv5Crsc Nzsa1uq7dOC+JLZ5y96SUng825WdGX+HiIf7QyUFPzpnqyYc4+ROwNb80ObPWQZU dctatP2g9Jk2ImmJbGQVeDXKAiqrMM3hf1bOF3N3VV9DpqID0z/S8l8H9mz7x9yl opd6kXxCPFKLgmAbMxcsytUduxZrJEcCpy3jPpIvjJ3BrzaGZlgjytqc2tYvbv/L 9i//evmGTCNXfQPrWEcMpBPbMf+aSzb/9Im8THB42jpJVQ7kx3txVg6d+wb73oGf XHkm5mwrESAcnVGfxY5xRaaSK/L2k5Lg98J1K/BIHIKskjCTg5FdyrgeGwdtLg6T FuXEvK29FJgfMb7k2Mf25l/Lglzi4q4LxBO4wcAUb1OpaVeK2kgYJr1eniSKrE/v NF5/bD9h7sD1qbZLfk+lsTggBGfMBmthwp59jNb7V4cLkIFXwopgx2h/73jm6kn8 8fMCTlwOoktewbv0DdWCy0Sfaa0iCXMSJy+Y13GWlcEMvQn1VLtX7RbQzZq9X+tV C/qkp1SdXfPG3vJbkNnZh/eS12F6vDauYJ814s3VAeJKOoMJWABB6Jm2SoBwFM6v kpIRNzDyJ1oKhF4PxIrmGkv6PvRM/j5akspOwy/zdHB3FBVCGmyuoB9GE8Bg1Rw7 xyfdZthPDdvGyQ== =XhDE -----END PGP SIGNATURE----- Merge tag 'riscv-for-linus-5.12-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux Pull RISC-V fixes from Palmer Dabbelt: "A handful of fixes for 5.12: - fix the SBI remote fence numbers for hypervisor fences, which had been transcribed in the wrong order in Linux.
