devmap: eliminate unused arguments The optional 'table' pointer is a legacy part of the interface, which has been replaced by devmap_register_table()/devmap_add_entry(). The few in-tree callers have already adapted to this, so it can be removed. The 'l1pt' argument is already entirely unused within the function.

pmap_mapdev: Consistently use vm_paddr_t for the first argument. The devmap variants used vm_offset_t for some reason, and a few places explicitly cast bus addresses to vm_offset_t. (Probably those casts along with similar casts for vm_size_t should just be removed and instead permit the compiler to DTRT.)

riscv: Implement pmap_mapdev_attr This is needed for LinuxKPI's _ioremap_attr. This reuses the generic implementation introduced for aarch64, and itself requires implementing pmap_kenter, which is trivial to do given riscv currently treats all mapping attributes the same due to the Svpbmt extension not yet being ratified and in hardware.

arm64: fix early devmap assertion The purpose of this KASSERT is to ensure that we do not run out of space in the early devmap. However, the devmap grew beyond its initial size of 2MB in r336519, and this assertion did not grow with it. A devmap mapping of a 1080p framebuffer requires 1920x1080 bytes, or 1.977 MB, so it is just barely able to fit without triggering the assertion, provided no other devices are mapped before it. With the addition of `options GDB` in GENERIC by bbfa199cbc16, the uart is now mapped for the purposes of a debug port, before mapping the framebuffer. The presence of both these conditions pushes the selected virtual address just below the threshold, triggering the assertion. To fix this, use the correct size of the devmap, defined by PMAP_MAPDEV_EARLY_SIZE. Since this code is shared with RISC-V, define it for that platform as well (although it is a different size).

o Replace __riscv__ with __riscv o Replace __riscv64 with (__riscv && __riscv_xlen == 64) This is required to support new GCC 7.1 compiler. This is compatible with current GCC 6.1 compiler. RISC-V is extensible ISA and the idea here is to have built-in define per each extension, so together with __riscv we will have some subset of these as well (depending on -march string passed to compiler): __riscv_compressed __riscv_atomic __riscv_mul __riscv_div __riscv_muldiv __riscv_fdiv __riscv_fsqrt __riscv_float_abi_soft __riscv_float_abi_single __riscv_float_abi_double __riscv_cmodel_medlow __riscv_cmodel_medany __riscv_cmodel_pic __riscv_xlen Reviewed by: ngie Sponsored by: DARPA, AFRL Differential Revision: https://reviews.freebsd.org/D11901

Include machine/acle-compat.h in cdefs.h on arm if the compiler doesn't have ACLE support built in. The ACLE (ARM C Language Extensions) defines a set of standardized symbols which indicate the architecture version and features available. ACLE support is built in to modern compilers (both clang and gcc), but absent from gcc prior to 4.4. ARM (the company) provides the acle-compat.h header file to define the right symbols for older versions of gcc. Basically, acle-compat.h does for arm about the same thing cdefs.h does for freebsd: defines standardized macros that work no matter which compiler you use. If ARM hadn't provided this file we would have ended up with a big #ifdef __arm__ section in cdefs.h with our own compatibility shims. Remove #include <machine/acle-compat.h> from the zillion other places (an ever-growing list) that it appears. Since style(9) requires sys/types.h or sys/param.h early in the include list, and both of those lead to including cdefs.h, only a couple special cases still need to include acle-compat.h directly.
