MIPS: OCTEON: irq: Fix octeon_irq_force_ciu_mapping()

2022-09-07T13:08:04Z

For irq_domain_associate() to work the virq descriptor has to be pre-allocated in advance. Otherwise the following happens: WARNING: CPU: 0 PID: 0 at .../kernel/irq/irqdomain.c:527 irq_domain_associate+0x298/0x2e8 error: virq128 is not allocated Modules linked in: CPU: 0 PID: 0 Comm: swapper/0 Not tainted 4.19.78-... #1 ...

MIPS: octeon: Get rid of preprocessor directives around RESERVE32

2022-09-07T12:55:16Z

Some of them were pointless because CONFIG_CAVIUM_RESERVE32 is now always defined, some were not enough (Yu Zhao reported "Failed to allocate CAVIUM_RESERVE32 memory area" error). Removing the directives allows for compiler coverage of RESERVE32 code and replacing one of [always-true] "ifdef" with a compiler conditional fixes the [cosmetic] error message.

Revert "MIPS: octeon: Remove vestiges of CONFIG_CAVIUM_RESERVE32"

This reverts commit e98b461bb057aaea6fa766260788c08825213837. We actually have been using the CONFIG_CAVIUM_RESERVE32 and previous patch defined it in the corresponding Kconfig. Signed-off-by: Alexander Sverdlin Signed-off-by: Thomas Bogendoerfer

This options is used to reserve a shared memory region for user processes to use for hardware memory buffers. The actual code to support the option comes in the following patch. Signed-off-by: Corey Minyard Signed-off-by: Alexander Sverdlin Signed-off-by: Thomas Bogendoerfer

genirq: Return a const cpumask from irq_data_get_affinity_mask

2022-07-07T08:38:04Z

Now that the irq_data_update_affinity helper exists, enforce its use by returning a a const cpumask from irq_data_get_affinity_mask. Since the previous commit already updated places that needed to call irq_data_update_affinity, this commit updates the remaining code that either did not modify the cpumask or immediately passed the modified mask to irq_set_affinity.

mips: cavium-octeon: Fix missing of_node_put() in octeon2_usb_clocks_start

We should call of_node_put() for the reference 'uctl_node' returned by of_get_parent() which will increase the refcount. Otherwise, there will be a refcount leak bug. Signed-off-by: Liang He Signed-off-by: Thomas Bogendoerfer
