[linux-yocto] [kernel-cache][PATCH] housekeeping: remove Kconfigs which no longer exist in the kernel

[Mark Asselstine]

While working with meta-virtualization I was cleaning up build
warnings:
        WARNING: linux-yocto-4.18.21+gitAUTOINC+9e348b6f9d_db2d813869-r0
        do_kernel_configcheck: [kernel config]: This BSP sets config
        options that are not offered anywhere within this kernel:

        CONFIG_EXT3_FS_XATTR
        CONFIG_RESOURCE_COUNTERS
        CONFIG_CGROUP_MEM_RES_CTLR
        CONFIG_CLS_CGROUP
        CONFIG_NETPRIO_CGROUP
        CONFIG_DEVPTS_MULTIPLE_INSTANCES

Most of these were coming from a configuration fragment included in
meta-virtualization but some are also found here in the
kernel-cache. So while I had the history handy to complete the commit
for meta-virtualization I thought it best to do similar cleanup
here. The follow 3 kconfigs have been removed from the kernel-cache,
per the provided rationale.

CONFIG_DEVPTS_MULTIPLE_INSTANCES removed since kernel v4.7 via mainline
commit eedf265aa003b4781de24cfed40a655a664457e6

CONFIG_EXT3_FS_XATTR was revoved since kernel v4.3 via mainline
commit c290ea01abb7907fde602f3ba55905ef10a37477

CONFIG_RESOURCE_COUNTERS gone since kernel v3.19 via mainline
commit 5b1efc027c0b51ca3e76f4e00c83358f8349f543.

This set of changes was put together while I had the details handy as
I was doing some kconfig cleanup in meta-virtualization. I know that
there might be reasons to not merge these into the kernel-cache as
older kernels might still be needed to be generated with the
kernel-cache. At any rate I had the information handy and these could
be applied to the 4.19/dev kernel directly, by sending it out the
information is available for anyone looking.
