syscalls: Get rid of register variables · bf41dcac

Cyrill Gorcunov authored Oct 31, 2011

It's been found that gcc 4.1.2 20080704 (Red Hat 4.1.2-48)
ignores register variables so to be on a safe side rewrite
syscalls with inline assembly without them.

nb: gcc version 4.6.1 20110908 (Red Hat 4.6.1-9) (GCC)
compiles them correctly.

restore: Call for sigreturn · 5b6748b4

Cyrill Gorcunov authored Oct 29, 2011

Prepare the stack value and do a syscall.
Still it fails because of stack corruption
I think and due to lack of setup of several
important values on thread-info area.

restore: Add some more structures for frame setup · b99eae28

Cyrill Gorcunov authored Oct 28, 2011

Some of them are already in system header files
but until I debug all things I simply picked up
kernel's definitions just to be more-less safe.

Since VMA areas are allocated with page granularity
better to reflect this in mmap request. This would
allow the restorer to do munmap on page boundaries.
