Hi
I am Aditya Garg. I often require using out of tree drivers to support various
hardwares on Linux. Sometimes the provider doesn't write good drivers, and
often they have to be force unloaded. It's a common thing in proprietary
drivers. I know the author of the driver should take note of the

Sorry, this is a stupid mistake.
I wonder if the gfp parameter in static inline void *kmalloc(size_t s, gfp_t gfp) can be deleted if it is not used.
Or would be better to move memset to kmalloc.
Like this:

(ARCH_HAS_PTE_DEVMAP). Claim another RSW (reserved for software) bit
in the PTE for DEVMAP mark, add the corresponding helpers, and enable

The pfn_to_kaddr() function is used by KASAN's memory hotplugging
path. Add the missing function to the RISC-V port, so that it can be

During memory hot remove, the ptdump functionality can end up touching
stale data. Avoid any potential crashes (or worse), by holding the
memory hotplug read-lock while traversing the page table.
This change is analogous to arm64's commit bf2b59f60ee1 ("arm64/mm:

For an architecture to support memory hotplugging, a couple of
callbacks needs to be implemented:
arch_add_memory()
This callback is responsible for adding the physical memory into the
direct map, and call into the memory hotplugging generic code via
__add_pages() that a

Prepare for memory hotplugging support by changing from __init to
