Subject: [PATCH 00/17] Introduce and use generic parity32/64 helper
Date: Mon, 24 Feb 2025 00:42:00 +0800	[thread overview]
Message-ID: <20250223164217.2139331-1-visitorckw@gmail.com> (raw)

Several parts of the kernel contain redundant implementations of parity
calculations for 32-bit and 64-bit values. Introduces generic
parity32() and parity64() helpers in bitops.h, providing a standardized
and optimized implementation.  

Subsequent patches refactor various kernel components to replace
open-coded parity calculations with the new helpers, reducing code
duplication and improving maintainability.
