Consolidation of bus (PCI, PCMCIA, EISA, RapidIO) config entries by Christoph Hellwig. Currently, every architecture that wants to provide common peripheral busses needs to add some boilerplate code and include the right Kconfig files. This series instead just selects the presence (when needed) and then handles everything in the bus-specific Kconfig file under drivers/. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJcJilwAAoJED2LAQed4NsGt1YP/RMTEUqbCSwS/CnTLrE+aVTC O2aWwB80ZlVwpeBbHLW5/M88OvOev0UaCr+gyzgpFRl5ITzS7Jevb8VbpGzblbH7 bFxIEyZFGQiy9oEWw3Lfu9JRSsLm3jNo7hkmdBSn2Rw3KkEd/YF7K3q9GuA7BpCS ZxAirebvEpr4KYEzkuc57NqCYx2Tc8G+JWr5D7pZCFaq9vxYt3TddGqw/c7iQVSQ 1Og1809IdhGyCSlA/ExfaqaBMaJHMRAOHX5GgkqZw1EbFcizUFhAAsKCrGL5nBtX NiWF9jhgHR1M+L69jfctOstrmGQD2KicNgWQf1aS5RQkPfjuqIKGT/i9g6J1pVyX TaW1J36Hcl8PpsKoPBnnrixd1T41O3/PuqtEJRm7LCBYOQiwS9sEmLO09RDRjER8 SPAAyvkhE8oq+0RHiTYN4tm8dyJc1djZ5wzgLnwFPAnU6SR+mbN02RzBMsYZXD+x RNbBSGBRJFQDBw6Rn+ktcIQvcKYmUqe1k1YNHMy6kG3QqvhBaDy+8PA/YjIKPQYQ B/NNUAMEJMys1OQrRL2UDXb2ysaCpzwMmlrBW2IwYsQrX5OwbPkNuQ5Mbe1Lr+mc 4NXR+HubvojsHaAby+OhFbrUX2Jcz3wqYj7aannb9sMRmw0VJXV5dPYUqje3ZhPS P2AovKT8O9nWsEttqER5 =WxId -----END PGP SIGNATURE----- Merge tag 'kconfig-v4.21-2' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild Pull Kconfig file consolidation from Masahiro Yamada: "Consolidation of bus (PCI, PCMCIA, EISA, RapidIO) config entries by Christoph Hellwig.

On some platforms, there is currently no way for the boot loader
|
|
to pass arguments to the kernel. For these, you should supply some
|
|
command-line options at build time by entering them here. At a
|
|
minimum, you should specify the memory size and the root device
|
|
(e.g., mem=64M root=/dev/nfs).

This allows you to specify the maximum number of CPUs which this
|
|
kernel will support. The maximum supported value is 6 and the
|
|
minimum value which makes sense is 2.
|
|
|
|
This is purely to save memory - each supported CPU adds
|
|
approximately eight kilobytes to the kernel image.
