The standard UNIX tool to get processes information, need to have the
process id inside /proc/<PID>/status.
Using ps without PID in /proc/<PID>/status gives :
PID TTY TIME CMD
2551 pts/0 00:00:00 bash
0 pts/0 00:00:00 exe
0 pts/0 00:00:00 exe
With this patch:
PID TTY TIME CMD
2551 pts/0 00:00:00 bash
11966 pts/0 00:00:00 exe
12619 pts/0 00:00:00 exe

Some are important, e.g. the seemingly harmless braces around if with dprintf,
since that dprintf is defined as empty, will screw things up and grab the next
line

search_free_space changed since this was implemented and the code is
no longer compatible
Looking at it again, the function is not used anywhere other than syscall.c
and the second function does not seem to fix anything specific so this
just removes the untested side.

do_frees is allowed to be NULL only if free_addrs_count is 0, but that
is increased to account for the wakeup_desc itself before this failure

Surplus refs on the linux side will not change anything, so spare
ourselves a message.
The final message will free all refs at once when the object is
destroyed.

init_normal_area was mapping identity lookups (phys = virt) from 0,
leading to many undetected null pointer dereferences in init_pt (but
not in new process page tables leading to odd behaviour)
This also makes the code use the set_pt_large_page() function, cleaning
it up a bit

This helps catching errors like accessing a field that no longer exists
in a debug print that wasn't compiled...

Was done in x86_64 for fileobj in commit 249bda4aef ("fileobj: use

GCC optimizes big switches with sse so we could clobber users floating
point registers when they would do a syscall
Reproducer:
```
#include <stdio.h>
#include <stdlib.h>
union num {
float f;
unsigned long long i;
};
#define WORKSIZE (1024 * 1024 * 32)
int main(int argc, char **argv) {
char *work = malloc(WORKSIZE);
char *fromaddr;
char sink;
union num r;
unsigned long long int offset;
r.f = drand48();
printf("r: %llx\n", (long long)r.i);
offset = (long long int)(r.f * (double)WORKSIZE);
fromaddr = work + offset;
printf("%e %llx %llx\n", r.f, offset, fromaddr);
sink = *fromaddr;
return 0;
}
```

Behave in the same way as Linux which returns old_address when
old_size == new_size && !MREMAP_FIXED.

While we are here, also optimize code a bit: perf_desc does not need
to be allocated for every cpu; and fix coding style.
