Subject: ide: limit legacy VLB host drivers to alpha, x86 and mips
X-Git-Tag: v2.6.26-rc1~1148^2~5
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=e4079df0c273719f539aaa7cc19ed17c9a5b0aba;p=linux-2.6-omap-h63xx.git

ide: limit legacy VLB host drivers to alpha, x86 and mips

These host drivers indirectly depend on CONFIG_IDE_ARCH_OBSOLETE_DEFAULTS=y
which is defined only on alpha, x86, ia64, m32r, mips and ppc32.

Moreover:

- on ia64 there is no ISA

- m32r is too new for VLB

- on ppc32 ISA is available only on PPC_CHRP (no default IDE ports)
  and PPC_PREP (marked as BROKEN)

[ the common sense tells me that VLB was only used on x86 but there
  are urban legends that one of these host drivers was needed on some
  other arch - thus the extra care ]
