Test Plan

Linux ARM : Add core emulation files

[soutade_gmail.com]

Update linux_set_tls() functions. md_tp field not present anymore for arch >= v6.

Looks like patch to sys/conf/files.arm was not included in either of revisions. It should contain all source files in sys/arm/linux/. Gregory, could you include this change and attach to any of the existing revisions?

It feels like much of linux.h could be shared with i386. There may be more that should be shared, but I am yet to have a chance to look too deeply.

sys/arm/linux/linux.h

268

Why is this packed?

sys/arm/linux/linux_machdep.c

73

This should be <machine/pcb.h>

[soutade_gmail.com]

sys/arm/linux/linux.h

I had a problem with gcc compiler used for Linux application.

[soutade_gmail.com]

Use <machine/pcb.h> instead of <arm/include/pcb.h>

[soutade_gmail.com]

Remove old Linux syscalls (not presents in Linux calls.S). Add dummy linux_syscall.

[andrew]

sys/arm/linux/linux.h

Can you go into more details on the problem?

sys/arm/linux/linux.h

The generated structure was not the same in term of alignment making the application crash when using signals.

Remove obsolete syscalls. Add linux_send() and linux_recv()
