Introduce a new module linux_common.ko which is intended for the following primary purposes: 1. Remove the dependency of linsysfs and linprocfs modules from linux.ko, which will be architecture specific on amd64. 2. Incorporate into linux_common.ko general code for platforms on which we'll support two Linuxulator modules (for both instruction set - 32 & 64 bit). 3. Move malloc(9) declaration to linux_common.ko, to enable getting memory usage statistics properly. Currently linux_common.ko incorporates a code from linux_mib.c and linux_util.c and linprocfs, linsysfs and linux kernel modules depend on linux_common.ko. Temporarily remove dtrace garbage from linux_mib.c and linux_util.c Differential Revision: https://reviews.freebsd.org/D1072 In collaboration with: Vassilis Laganakos. Reviewed by: trasz

KMOD= linux_common
Fix a copy/paste bug introduced during X86_64 Linuxulator work. FreeBSD support NX bit on X86_64 processors out of the box, for i386 emulation use READ_IMPLIES_EXEC flag, introduced in r302515. While here move common part of mmap() and mprotect() code to the files in compat/linux to reduce code dupcliation between Linuxulator's.

Share a single bsd-linux errno table across MD consumers Three copies of the linuxulator linux_sysvec.c contained identical BSD to Linux errno translation tables, and future work to support other architectures will also use the same table. Move the table to a common file to be used by all. Make it 'const int' to place it in .rodata. (Some existing Linux architectures use MD errno values, but x86 and Arm share the generic set.) This change should introduce no functional change; a followup will add missing errno values. MFC after: 3 weeks Sponsored by: Turing Robotic Industries Inc.

linux_errno.c \
Our bsd_to_linux_sockaddr() and linux_to_bsd_sockaddr() functions alter the userspace sockaddr to convert the format between linux and BSD versions. That's the minimum 3 of copyin/copyout operations for one syscall. Also some syscall uses linux_sa_put() and linux_getsockaddr() when load sockaddr to userspace or from userspace accordingly. To avoid this chaos, especially converting sockaddr in the userspace, rewrite these 4 functions to convert sockaddr only in kernel and leave only 2 of this functions. Also in order to reduce duplication between MD parts of the Linuxulator put struct sockaddr conversion functions that are MI out into linux_common module.
