It seems this constructor could be simplified to:

GCMProfileService::GCMProfileService(
    scoped_ptr<GCMDriver> driver,
    scoped_ptr<ProfileIdentityProvider> identity_provider,
    net::URLRequestContextGetter* request_context)
    : driver_(driver),
      identity_provider_(identity_provider),
      request_context_(request_context) {
  identity_observer_.reset(new IdentityObserver(
      identity_provider_.get(), request_context_, driver_.get());
}

if you change the IdentityObserver constructor signature to:

IdentityObserver::IdentityObserver(ProfileIdentityProvider* identity_provider,
net::URLRequestContextGetter* request_context, GCMDriver* driver)

Or perhaps, to avoid duplicating all the pointers, you could even change that
constructor to just:

IdentityObserver::IdentityObserver(GCMProfileService* service);

Similarly for OS_ANDROID, except you'd just need:

GCMProfileService::GCMProfileService(scoped_ptr<GCMDriver> driver)
    : driver_(driver) {}
