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 Approved by: re (gjb) 2016-02-25T19:26:14Z Ed Maste emaste@FreeBSD.org 2016-02-25T19:26:14Z urn:sha1:621a9c54ddbc62bd047d5f787e78cc1954e5b153 -fPIC has no effect on linking although it seems to be ignored by GNU ld.bfd. However, it causes ld.lld to terminate with an invalid argument error.

Linux sigset always 64 bit on all platforms. In order to move Linux sigset code to the linux_common module define it as 64 bit int. Move Linux sigset manipulation routines to the MI path. 2. Move Linux signal number definitions to the MI path. In general, they are the same on all platforms except for a few signals. 3. Map Linux RT signals to the FreeBSD RT signals and hide signal conversion tables to avoid conversion errors. 4. Emulate Linux SIGPWR signal via FreeBSD SIGRTMIN signal which is outside of allowed on Linux signal numbers.

The kqueue user data are 32bit on i386 which is not enough for epoll user data, so we keep user data in the proc emuldata. Initial patch developed by rdivacky@ in 2007, then extended by Yuri Victorovich @ r255672 and finished by me in collaboration with mjg@ and jillies@.

As we can have both 64 & 32 bit Linuxulator running any eventhandler can be called twice for us. To prevent this move eventhandlers code from linux_emul.c to the linux_common.ko module.

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.
