This was mainly broken by 7e82012aff9888d64a85d19aaed51def9ebbff22 and r178192 respectively. Also, remove unused #include.

Avoid dump_avail[] redefinition.

Move dump_avail[] extern declaration and inlines into a new header vm/vm_dumpset.h. This fixes default gcc build for mips. Reviewed by: alc, scottph Tested by: kevans (previous version) Sponsored by: The FreeBSD Foundation Differential revision: https://reviews.freebsd.org/D26741

Query MVPConf0.PVPE for number of CPUs.

Rather than hard-coding the number of CPUs to 2, look up the PVPE field in MVPConf0, as the valid VPE numbers are from 0 to PVPE inclusive. Submitted by: "James Clarke" Reviewed by: br Sponsored by: DARPA, AFRL Differential Revision: https://reviews.freebsd.org/D16644

Support 2GB of memory on Malta systems with FreeBSD/mips.

2018-06-28T21:27:34Z

When 2GB of memory is enabled for QEMU's Malta emulation, the physical memory ends at an address of 2^32 - 1. This causes an integer overflow to zero when computing the upper bound of the second phys_avail[] range. As a result, FreeBSD/mips kernels were only using the first 256MB of RAM and ignoring the remaining 1.75GB. To work around this, truncate the extended memory size to 2GB minus one page for 32-bit mips kernels. Sponsored by: DARPA / AFRL Differential Revision: https://reviews.freebsd.org/D16027
