Hm. These deltas are huge. :( It would be interesting to know where
they come from.
As far as the tegra_defconfig build size deltas go, the short story is:
+ 110KB from v3.11-rc7 to v3.12-rc1, using the same v3.11-rc7
tegra_defconfig
+ 99KB after CONFIG_USB_XHCI_HCD=y
+ 51KB when the various CONFIG_PCI* changes are added
+ 36KB after CONFIG_SYSVIPC=y
+ 10KB after CONFIG_MOUSE_PS2_ELANTECH=y
Details below.
Still need to look into the boot memory size differences.
