Subject: [PATCH 1/2] drb: remove note about "ramdisk" kernel parameter

The ramdisk kernel parameter was finally removed in commit
1adbee50fd6fce5af4feb34d2db93cfe4d2066a4 ("ramdisk: remove
long-deprecated "ramdisk=" boot-time parameter"). It had been marked as
deprecated since v1.3.96! Remove this note from its Kconfig entry.

0) The ramdisk kernel parameter was rather stubborn. It had to be
removed from the tree three times:
- in release v1.3.48 - re-added in v1.3.96;
- in v2.6.24, with commit fac8b209b1084bc85748bd54e13d00c1262b220f
("Remove final traces of long-deprecated "ramdisk" kernel parm") -
re-added in v2.6.25, with commit
9db5579be4bb5320c3248f6acf807aedf05ae143 ("rewrite rd);
- in v2.6.31, with commit 1adbee50fd6fce5af4feb34d2db93cfe4d2066a4 (see
above).

1) But references to it still get added to command lines in defconfig
files and device tree sources, all in arch/arm. As recently as v3.6-rc1!
I guess it is now (silently?) ignored if used in one of those command
lines. Or does arm use some obscure trick to still handle this kernel
parameter?
