Histogram doesn't show all of large binaries

[Rot127]

Work environment

Questions	Answers
OS/arch/bits (mandatory)	Debian arm 64, Ubuntu x86 32
File format of the file you reverse (mandatory)	PE, ELF etc.
Architecture/bits of the file (mandatory)	PPC, x86/32, x86/64 etc.
rizin -v full output, not truncated (mandatory)	dev

Expected behavior

The histogram (p== commands) shows by default the whole binary.
So everything should fit on the screen, even if the binary is large.

Actual behavior

The histogram stops at some address:

[0x8d400000]> s 0
[0x00000000]> iSS
     paddr      size      vaddr     vsize  align perm name

As above.

[Rot127]

This might not be such a big bug.
It seems like the histogram reads the data from vfiles.
The Qualcomm firmware tested here uses vfiles to map all the different binaries of that firmware.

In the second example (0xbc600000) it can be seen that the histogram has exactly the size of the map.

That is actually pretty sensible if documented.

There seems to be still a bug though with the first example (at 0x0). There it doesn't seem to match any map.
