coccinelle: alloc_cast: drop removed allocatorsgrafted
- pci_alloc_consistent() and pci_zalloc_consistent() were removed by commit 7968778914e5 ("PCI: Remove the deprecated "pci-dma-compat.h" API") - kmem_alloc() was removed by commit f078d4ea8276 ("xfs: convert kmem_alloc() to kmalloc()") - kmem_zalloc() was removed by commit 10634530f7ba ("xfs: convert kmem_zalloc() to kzalloc()") - kmem_zone_alloc() and kmem_zone_zalloc() were removed by commit bae633a4a283 ("xfs: remove xfs_zone_{alloc,zalloc} helpers") So drop them from the rules. No functional change. Signed-off-by: Sang-Heon Jeon <ekffu200098@gmail.com> Signed-off-by: Julia Lawall <Julia.Lawall@inria.fr>

+What: /sys/kernel/irq
+Date: September 2016
+KernelVersion: 4.9
+Contact: Craig Gallek <kraig@google.com>
+Description: Directory containing information about the system's IRQs.
+ Specifically, data from the associated struct irq_desc.
+ The information here is similar to that in /proc/interrupts
+ but in a more machine-friendly format. This directory contains
+ one subdirectory for each Linux IRQ number.
+
+What: /sys/kernel/irq/<irq>/actions
+Date: September 2016
+KernelVersion: 4.9
+Contact: Craig Gallek <kraig@google.com>
+Description: The IRQ action chain. A comma-separated list of zero or more
+ device names associated with this interrupt.
+
+What: /sys/kernel/irq/<irq>/chip_name
+Date: September 2016
+KernelVersion: 4.9
+Contact: Craig Gallek <kraig@google.com>
+Description: Human-readable chip name supplied by the associated device
+ driver.
+
+What: /sys/kernel/irq/<irq>/hwirq
+Date: September 2016
+KernelVersion: 4.9
+Contact: Craig Gallek <kraig@google.com>
+Description: When interrupt translation domains are used, this file contains
+ the underlying hardware IRQ number used for this Linux IRQ.
+
+What: /sys/kernel/irq/<irq>/name
+Date: September 2016
+KernelVersion: 4.9
+Contact: Craig Gallek <kraig@google.com>
+Description: Human-readable flow handler name as defined by the irq chip
+ driver.
+
+What: /sys/kernel/irq/<irq>/per_cpu_count
+Date: September 2016
+KernelVersion: 4.9
+Contact: Craig Gallek <kraig@google.com>
+Description: The number of times the interrupt has fired since boot. This
+ is a comma-separated list of counters; one per CPU in CPU id
+ order. NOTE: This file consistently shows counters for all
+ CPU ids. This differs from the behavior of /proc/interrupts
+ which only shows counters for online CPUs.
+
+What: /sys/kernel/irq/<irq>/type
+Date: September 2016
+KernelVersion: 4.9
+Contact: Craig Gallek <kraig@google.com>
+Description: The type of the interrupt. Either the string 'level' or 'edge'.
+
+What: /sys/kernel/irq/<irq>/wakeup
+Date: March 2018
+KernelVersion: 4.17
+Contact: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
+Description: The wakeup state of the interrupt. Either the string
+ 'enabled' or 'disabled'.
