Subject: [PATCH v2 0/9] accel/tcg: Fix page_set_flags and related [#1528]
Date: Fri, 17 Mar 2023 08:54:46 -0700 [thread overview]
Message-ID: <20230317155455.341843-1-richard.henderson@linaro.org> (raw)
The primary issue is that of overflow, where "end" for the last
page of the 32-bit address space overflows to 0. The fix is to
use "last" instead, which can always be represented.
Changes for v2:
* Leave -R 0 unchanged; whether it's currently broken,
or unusable by design is unchanged by this patch set.
* Drop reserved_va -> max_reserved_va name change;
it doesn't really make sense.
Require review:
01-linux-user-Diagnose-misaligned-R-size.patch
03-include-exec-Replace-reserved_va-with-max_reserve.patch
08-accel-tcg-Pass-last-not-end-to-tb_invalidate_phys.patch
