From d5ece1cb074b2c7082c9a2948ac598dd0ad40657 Mon Sep 17 00:00:00 2001 From: James Hogan Date: Sat, 26 Dec 2015 22:47:52 +0000 Subject: Fix ld-version.sh to handle large 3rd version part The ld-version.sh script doesn't handle versions with large (>= 10) 3rd version components, because the 2nd component is only multiplied by 10 times that of the 3rd component. For example the following version string: GNU ld (Codescape GNU Tools 2015.06-05 for MIPS MTI Linux) 2.24.90 gives a bogus version number: 20000000 + 2400000 + 900000 = 23300000 Breakage, confusion and mole-whacking ensues. Increase the multipliers of the first two version components by a factor of 10 to give space for a 3rd components of up to 99, and update the sole user of ld-ifversion (MIPS VDSO) accordingly.

It was originally sent in an earlier revision of the pfn_t patchset. Besides being broken, the warning is also fixed by PFN_FLAGS_MASK casting the PAGE_MASK to an unsigned long.

If a core has been configured in hardware to start in EVA mode, these assumptions will fail. This patch ensures that secondary cores are initialized to meet these assumptions.
