Kconfig tweaks to help reduce RTC configuration bugs, by avoiding legacy RTC drivers when the generic RTC framework is enabled: - If rtc-cmos is selected, disable the legacy rtc driver; - When using generic RTC on x86, enable rtc-cmos by default; - In the old "chardev RTC" section of Kconfig, add a comment warning people off these (seven) legacy RTC drivers when the generic framework is in use. People can still use the legacy drivers if they want (or need) to. This doesn't fix the broken dependencies for the legacy "CMOS" RTC driver. Ideally it would be a full list of platforms where it works, not a partial list of ones where it won't. Or better yet, it would depend on a "HAVE_CMOS_RTC" flag defined by various platforms ... surely there's a Kconfig style guideline lurking there. Signed-off-by:

Add a 'count' variable to each symbol which gets increased every time the symbol is referenced. And then modify the register definition to include counts for symbols which are referenced from the source code only and not from the sequencer code. This will give us an automatic usage count for the symbols with only minimal hand-crafting. Signed-off-by: -

Commit 63a8651f ([SCSI] qla2xxx: Correct infinite-login-retry issue.) introduced a small regression where a successful relogin would result in an fcport's loop_id to be incorrectly reset to FC_NO_LOOP_ID. Only clear-out loopid, if retries have been 'truly' exhausted. Signed-off-by:

The driver is incorrectly assuming that the 'sp' reference held in qla2[x00|4xx]_abort_command() is valid after the mailbox command is issued to abort the exchange. It is *not*, as the command may be completed during interrupt context before control is returned to the mailbox caller. Signed-off-by:

Use the more efficient read-DMA'ble-buffer mailbox commands rather than reading a single word/dword at a time. We also remove a bulk of the duplicate mailbox command-handling codes in favor of more generic read-memory() routines (qla2xxx_dump_ram() and qla24xx_dump_ram()). Signed-off-by:

Replace the mac_esp driver with a new one based on the esp_scsi core. For esp_scsi: add support for sync transfers for the PIO mode, add a new esp_driver_ops method to get the maximum dma transfer size (like the old NCR53C9x driver), and some cleanups. Signed-off-by:

The new FCP adapter statistics provide a variety of information about the virtual adapter (subchannel). In order to collect this information the zfcp driver is extended to query this information. The information provided by the new FCP adapter statistics can be fetched by reading from the following files in the sysfs filesystem /sys/class/scsi_host/host<n>/seconds_active /sys/class/scsi_host/host<n>/requests /sys/class/scsi_host/host<n>/megabytes /sys/class/scsi_host/host<n>/utilization These are the statistics on a virtual adapter (subchannel) level. The information provided is raw and not modified or interpreted by any means. No interpretation or modification of the values is done by the zfcp driver. Signed-off-by:

When sending a exchange config data command, wait for a free SBAL. This does not matter during adapter initialization, but this is required for pulling adapter statistics during high I/O load. Signed-off-by:

Way back when, when the fc_user_scan routine was created, it kept some of its original logic that walked the rport list and kicked off a scan. Unfortunately, it didn't keep any of the locking around the rport list, nor did it consider the synchronous nature of the scan invoked. The result, there are some scan requests where the rport list changes, thus a subsequent scan is called on a bogus rport structure and the system NMI's. Signed-off-by:

We're getting a WARN_ON from SLUB indicating that we're trying to free caches with in-use objects. The root cause is a new dependency in the command/sense free on unchecked_isa_dma. The WARN_ON is caused by drivers which change this in their setup after the command/sense cache is allocated. The fix is to move the allocation of this cache into scsi_add_host() so things like gdth have an opportunity to modify it between alloc and add (but *not* after). The true fix would be to move unchecked_isa_dma into the template and out of the host, so it because a truly read only variable. Signed-off-by: -
