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.

help
|
|
Select this option, if you want to enable support for IO Event
|
|
interrupts. IO event interrupt is a mechanism provided by RTAS
|
|
to return information about hardware error and non-error events
|
|
which may need OS attention. RTAS returns events for multiple
|
|
event types and scopes. Device drivers can register their handlers
|
|
to receive events.
|
|
|
|
This option will only enable the IO event platform code. You
|
|
will still need to enable or compile the actual drivers
|
|
that use this infrastructure to handle IO event interrupts.
|
|

|
Say Y if you are unsure.

Select this option, if you want to enable the kernel interface
|
|
to reduce the memory size of the system. This is accomplished
|
|
by allocating pages of memory and put them "on hold". This only
|
|
makes sense for a system running in an LPAR where the unused pages
|
|
will be reused for other LPARs. The interface allows firmware to
|

balance memory across many LPARs.
