arch: powerpc: ps3: Make ps3_system_bus_type const

2025-10-22T05:55:05Z

Because driver core can properly handle constant struct bus_type, move the ps3_system_bus_type to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.

powerpc: Switch irq_domain_add_nomap() to use fwnode

2025-05-16T19:06:11Z

All irq_domain_add_*() functions are going away. PowerPC is the only user of irq_domain_add_nomap() and there is no irq_domain_create_nomap() complement. Therefore, to align with the rest of the kernel, rename irq_domain_add_nomap() to irq_domain_create_nomap() and accept a fwnode_handle instead of a device_node.

irqdomain: Rename irq_set_default_host() to irq_set_default_domain()

2025-04-04T14:39:10Z

Naming interrupt domains host is confusing at best and the irqdomain code uses both domain and host inconsistently. Therefore rename irq_set_default_host() to irq_set_default_domain().

mm/ioremap: pass pgprot_t to ioremap_prot() instead of unsigned long

2025-03-17T05:06:23Z

ioremap_prot() currently accepts pgprot_val parameter as an unsigned long, thus implicitly assuming that pgprot_val and pgprot_t could never be bigger than unsigned long. But this assumption soon will not be true on arm64 when using D128 pgtables. In 128 bit page table configuration, unsigned long is 64 bit, but pgprot_t is 128 bit. Passing platform abstracted pgprot_t argument is better as compared to size based data types. Let's change the parameter to directly pass pgprot_t like another similar helper generic_ioremap_prot(). Without this change in place, D128 configuration does not work on arm64 as the top 64 bits gets silently stripped when passing the protection value to this function.

mm/memblock: add memblock_alloc_or_panic interface

2025-01-26T04:22:38Z

Before SLUB initialization, various subsystems used memblock_alloc to allocate memory. In most cases, when memory allocation fails, an immediate panic is required. To simplify this behavior and reduce repetitive checks, introduce `memblock_alloc_or_panic`. This function ensures that memory allocation failures result in a panic automatically, improving code readability and consistency across subsystems that require this behavior.
