Subject: [PATCH 0/6] ARM: cleanup fault handling
Date: Fri, 27 Feb 2026 15:18:26 +0000 [thread overview]
Message-ID: <aaG1wrNUaq_L0I5g@shell.armlinux.org.uk> (raw)
Hi,
This series cleans up the 32-bit ARM fault handling:
1. ensure a consistent IRQ state in the user fault processing path.
2. split vmalloc fault processing in a similar way to x86
3. move is_..._fault() to the local fault.h header file
4. update the FSR deifnitions using BIT() and GENMASK()
5. move LPAE/non-LPAE specific FSR bits/masks along side users
6. get rid of #ifdefs within is_..._fault() by providing a LPAE
and non-LPAE versions.
