[ Upstream commit 05ad5482 ] The hip08 split two hardware version. The version id are 0x20 and 0x21 according to the PCI revison. The max size of extend sge of sq is limited to 2M for 0x20 version and 8M for 0x21 version. It may be exceeded to 2M according to the algorithm that compute the product of wqe count and extend sge number of every wqe. But the product always less than 8M. Signed-off-by:

[ Upstream commit 059421e0 ] Commit 35bfc521 ("md: allow metadata update while suspending.") added support for allowing md_check_recovery() to still perform metadata updates while the array is entering the 'suspended' state. This is needed to allow the processes of entering the state to complete. Unfortunately, the patch doesn't really work. The test for "mddev->suspended" at the start of md_check_recovery() means that the function doesn't try to do anything at all while entering suspend. This patch moves the code of updating the metadata while suspending to *before* the test on mddev->suspended. Reported-by:

[ Upstream commit 37e7742c ] The driver seems to abuse *unsigned long* not only for the (32-bit) register values but also for the 'sh_cmt_channel::total_cycles' which needs to always be 64-bit -- as a result, the clocksource's mask is needlessly clamped down to 32-bits on the 32-bit machines...

[ Upstream commit 22627c6f ] When trying to use CMT for clockevents on R-Car gen3 SoCs, I noticed that 'max_delta_ns' for the broadcast timer (CMT) was shown as 1000 in /proc/timer_list. It turned out that when calculating it, the driver did 1 << 32 (causing what I think was undefined behavior) resulting in a zero delta, later clamped to 1000 by cev_delta2ns(). The root cause turned out to be that the driver abused *unsigned long* for the CMT register values (which are 16/32-bit), so that the calculation of 'ch->max_match_value' in sh_cmt_setup_channel() used the wrong branch. Using more proper 'u32' instead fixed 'max_delta_ns' and even fixed the switching an active clocksource to CMT (which caused the system to turn non-interactive before). Signed-off-by:

[ Upstream commit db787af1 ] When CONFIG_VIRT_CPU_ACCOUNTING_NATIVE is not set, we register the DTL buffer for a cpu when the associated file under powerpc/dtl in debugfs is opened. When doing so, we need to set the size of the buffer being registered in the second u32 word of the buffer. This needs to be in big endian, but we are not doing the conversion resulting in the below error showing up in dmesg: dtl_start: DTL registration for cpu 0 (hw 0) failed with -4 Fix this in the obvious manner.

[ Upstream commit 884e370e ] CON_PRINTBUFFER console registration requires us to do several preparation steps: - Rollback console_seq to replay logbuf messages which were already seen on other consoles; - Set exclusive_console flag so console_unlock() will ->write() logbuf messages only to the exclusive_console driver. The way we do it, however, is a bit racy logbuf_lock_irqsave(flags); console_seq = syslog_seq; console_idx = syslog_idx; logbuf_unlock_irqrestore(flags); << preemption enabled << irqs enabled exclusive_console = newcon; console_unlock(); We rollback console_seq under logbuf_lock with IRQs disabled, but we set exclusive_console with local IRQs enabled and logbuf unlocked. If the system oops-es or panic-s before we set exclusive_console - and given that we have IRQs and preemption enabled there is such a possibility - we will re-play all logbuf messages to every registered console, which may be a bit annoying and time consuming. Move exclusive_console assignment to the same IRQs-disabled and logbuf_lock-protected section where we rollback console_seq.

[ Upstream commit f92b070f ] The variable "exclusive_console" is used to reply all existing messages on a newly registered console. It is cleared when all messages are out. The problem is that new messages might appear in the meantime. These are then visible only on the exclusive console. The obvious solution is to clear "exclusive_console" after we replay all messages that were already proceed before we started the reply. Reported-by:
