Subject: [PATCH 0/4] arch: mm, vdso: consolidate PAGE_SIZE definition
Date: Mon, 26 Feb 2024 17:14:10 +0100
Message-Id: <20240226161414.2316610-1-arnd@kernel.org>
Precedence: bulk
MIME-Version: 1.0

From: Arnd Bergmann <arnd@arndb.de>

Naresh noticed that the newly added usage of the PAGE_SIZE macro in
include/vdso/datapage.h introduced a build regression. I had an older
patch that I revived to have this defined through Kconfig rather than
through including asm/page.h, which is not allowed in vdso code.

I rebased and tested on top of the tip/timers/core branch that
introduced the regression. If these patches get added, the
compat VDSOs all build again, but the changes are a bit invasive.

Arnd Bergmann (4):
  arch: consolidate existing CONFIG_PAGE_SIZE_*KB definitions
  arch: simplify architecture specific page size configuration
  arch: define CONFIG_PAGE_SIZE_*KB on all architectures
  vdso: avoid including asm/page.h
