Subject: decompress: fix new decompressor for PIC
From: Russell King <rmk@xxxxxxxxxxxxxxxx>
The ARM kernel decompressor wants to be able to relocate r/w data
independently from the rest of the image, and we do this by ensuring that
r/w data has global visibility. Define STATIC_RW_DATA to be empty to
achieve this.
