Subject: [PATCH 00/37] softirq: Per vector masking v3 
Date: Thu, 28 Feb 2019 18:12:05 +0100
Message-ID: <20190228171242.32144-1-frederic@kernel.org> (raw)

So this set should hopefully address all reviews from the v2, and
fix all reports from the extremely useful (as always) Kbuild testing
bot. It also completes support for all archs.

Unfortunately the already huge pile is ever growing. I should be able to
offload 2 or 3 of those patches but the rest really belong together.

Changes since v2:

* Fix unused function warning (reported by Kbuild test robot)
    - locking/lockdep: Move valid_state() inside CONFIG_TRACE_IRQFLAGS && CONFIG_PROVE_LOCKING

* Added Reviewed-by tags from davem

* Reorder changes introducing u64 to the proper patches (reported by Linus)

* Fix lock usage mask iteration by avoid shifting beyond 63 (reported by Linus)
    - locking/lockdep: Introduce lock usage mask iterator

* Fix mark_lock() verbosity by handling all usages in the ask
    - locking/lockdep: Report all usages on mark_lock() verbosity mode

* Add SPDX licence identifier on softirq_vector.h (reported by Sebastian)

* Fix several build errors on s390 (reported by Kbuild test robot)
    - arch/softirq: Rename softirq_pending fields to softirq_data
    - softirq: Introduce disabled softirq vectors bits
    - softirq: Check enabled vectors before processing

* Initialize softirq enabled field on all other archs than x86
    - parisc: Init softirq enabled field
    - powerpc: Init softirq enabled field
    - softirq: Init softirq enabled field for default irq_stat definition

* Fix spin_[un]lock_bh_mask() on UP, also some build errors against uninlined spinlocks (reported by Kbuild test robot)
    - locking: Introduce spin_[un]lock_bh_mask()

* Socket lock may also execute on HRTIMER_SOFTIRQ, include it on the mask (reported by Sebastian)
    - net: Make softirq vector masking finegrained on release_sock()
