Subject: [PULL 07/39] linux-user: Remove qemu_host_page_size from create_elf_tables
Date: Thu, 22 Feb 2024 10:42:51 -1000 [thread overview]
Message-ID: <20240222204323.268539-8-richard.henderson@linaro.org> (raw)
In-Reply-To: <20240222204323.268539-1-richard.henderson@linaro.org>
AT_PAGESZ is supposed to advertise the guest page size.
The random adjustment made here using qemu_host_page_size
does not match anything else within linux-user.
The idea here is good, but should be done more systemically
via adjustment to TARGET_PAGE_SIZE.
