Hm. These deltas are huge. :(  It would be interesting to know where
they come from.

In terms of the vmlinux object size deltas, if one compares with OMAP 
v3.11 -> v3.12-rc1:

  http://marc.info/?l=linux-omap&m=137990533109727&w=2

it appears that the 308KB tegra_defconfig delta is pretty close. 

As a historical observation, the past several -rc1s have seen considerable 
vmlinux size increases.  The Tegra data here doesn't go back very far yet, 
but here's the OMAP data:

+158KB: http://www.pwsan.com/omap/testlogs/test_v3.11-rc1/20130721020309/build/size.txt
+105KB: http://www.pwsan.com/omap/testlogs/test_v3.10-rc1/20130518212204/build/size.txt
+235KB: http://www.pwsan.com/omap/testlogs/test_v3.9-rc1/20130312100243/build/size.txt
+195KB: http://www.pwsan.com/omap/testlogs/test_v3.8-rc1/20121228031713/build/size.txt
 +63KB: http://www.pwsan.com/omap/testlogs/test_v3.7-rc1/20121017205513/build/size.txt

...

Regarding the boot-time memory differences, the ~300KB deltas look about 
right, but the 0KB and the ~600KB deltas seem incorrect.  Something is 
probably wrong with some of the scripts here.  Will follow up on that 
this week.

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.
