2019-06-18scsi: megaraid_sas: Block PCI config space access from userspace during OCRShivasharan S3-10/+74
While an online controller reset(OCR) is in progress, there is short duration where all access to controller's PCI config space from the host needs to be blocked. This is due to a hardware limitation of MegaRAID controllers. With this patch, driver will block all access to controller's config space from userland applications by calling pci_cfg_access_lock() while OCR is in progress and unlocking after controller comes back to ready state. Added helper function which locks the config space before initiating OCR and wait for controller to become READY.

2019-06-18scsi: megaraid_sas: Rework code around controller resetShivasharan S2-13/+11
No functional change. This patch reworks code around controller reset path which gets rid of a couple of goto labels. This is in preparation for the next patch which adds PCI config space access locking while controller reset is in progress.

2019-06-18scsi: megaraid_sas: fw_reset_no_pci_access required for MFI adapters onlyShivasharan S1-8/+10
fw_reset_no_pci_access is only applicable for MFI controllers and is not used for Fusion controllers. For all Fusion controllers, driver can check reset adapter bit in status register before performing a chip reset without setting "fw_reset_no_pci_access".

2019-06-18scsi: sd: Rely on the driver core for asynchronous probingBart Van Assche4-24/+7
As explained during the 2018 LSF/MM session about increasing SCSI disk probing concurrency, the problems with the current probing approach are as follows: - The driver core is unaware of asynchronous SCSI LUN probing. wait_for_device_probe() waits for all asynchronous probes except asynchronous SCSI disk probes. - There is unnecessary serialization between sd_probe() and sd_remove(). This can lead to a deadlock. Hence this patch that modifies the sd driver such that it uses the driver core framework for asynchronous probing. The async domain and get_device()/put_device() pairs that became superfluous due to this change are removed. This patch does not affect the time needed for loading the scsi_debug kernel module with parameters delay=0 and max_luns=256. This patch depends on commit ef0ff68351be ("driver core: Probe devices asynchronously instead of the driver") that went upstream in kernel version v5.1-rc1.
