  "message": "Don\u0027t lock guardpage if the stack is growing up\n\nLinux kernel excludes guard page when performing mlock on a VMA with\ndown-growing stack. However, some architectures have up-growing stack\nand locking the guard page should be excluded in this case too.\n\nThis patch fixes lvm2 on PA-RISC (and possibly other architectures with\nup-growing stack). lvm2 calculates number of used pages when locking and\nwhen unlocking and reports an internal error if the numbers mismatch.\n\n[ Patch changed fairly extensively to also fix /proc/\u003cpid\u003e/maps for the\n  grows-up case, and to move things around a bit to clean it all up and\n  share the infrstructure with the /proc bits.\n\n  Tested on ia64 that has both grow-up and grow-down segments  - Linus ]\n\nSigned-off-by: Mikulas Patocka \u003cmikulas@artax.karlin.mff.cuni.cz\u003e\nTested-by: Tony Luck \u003ctony.luck@gmail.com\u003e\nCc: stable@kernel.org\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
