* bsd-user: Catch up with sys/param.h requirement for machine/pmap.hMuhammad Moinur Rahman2022-10-262-0/+2
| | | | | | | | | | Some versions of FreeBSD now require sys/param.h for machine/pmap.h on x86. Include them here to meet that requirement. It does no harm on older versions, so there's no need to #ifdef it.

* accel/tcg: Call tb_invalidate_phys_page for PAGE_RESETRichard Henderson2022-10-261-2/+0Star
| | | | | | | | | | | | | | | | | When PAGE_RESET is set, we are replacing pages with new content, which means that we need to invalidate existing cached data, such as TranslationBlocks. Perform the reset invalidate while we're doing other invalidates, which allows us to remove the separate invalidates from the user-only mmap/munmap/mprotect routines. In addition, restrict invalidation to PAGE_EXEC pages. Since cdf713085131, we have validated PAGE_EXEC is present before translation, which means we can assume that if the bit is not present, there are no translations to invalidate.
