x86/defconfig: Enable CONFIG_DEBUG_WX=y

2022-09-02T08:41:42Z

7 years after it got introduced it's time to make this the default, at least in the x86 defconfigs. Signed-off-by: Ingo Molnar

x86/defconfig: Refresh the defconfigs

2022-09-02T08:37:53Z

Just go through a 'make savedefconfig' cycle to pick up fresh Kconfig details, no change in settings, just reordering of some entries. ( This makes followup changes generated via 'make savedefconfig' contain less noise. ) Signed-off-by: Ingo Molnar

Merge tag 'for-linus-6.0-rc3-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip

Pull xen fixes from Juergen Gross: - two minor cleanups - a fix of the xen/privcmd driver avoiding a possible NULL dereference in an error case * tag 'for-linus-6.0-rc3-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip: xen/privcmd: fix error exit of privcmd_ioctl_dm_op() xen: move from strlcpy with unused retval to strscpy xen: x86: remove setting the obsolete config XEN_MAX_DOMAIN_MEMORY

xen: x86: remove setting the obsolete config XEN_MAX_DOMAIN_MEMORY

2022-08-25T11:38:03Z

Commit c70727a5bc18 ("xen: allow more than 512 GB of RAM for 64 bit pv-domains") from July 2015 replaces the config XEN_MAX_DOMAIN_MEMORY with a new config XEN_512GB, but misses to adjust arch/x86/configs/xen.config. As XEN_512GB defaults to yes, there is no need to explicitly set any config in xen.config. Just remove setting the obsolete config XEN_MAX_DOMAIN_MEMORY.

efi: vars: Remove deprecated 'efivars' sysfs interface

2022-06-24T18:40:19Z

Commit 5d9db883761a ("efi: Add support for a UEFI variable filesystem") dated Oct 5, 2012, introduced a new efivarfs pseudo-filesystem to replace the efivars sysfs interface that was used up to that point to expose EFI variables to user space. The main problem with the sysfs interface was that it only supported up to 1024 bytes of payload per file, whereas the underlying variables themselves are only bounded by a platform specific per-variable and global limit that is typically much higher than 1024 bytes. The deprecated sysfs interface is only enabled on x86 and Itanium, other EFI enabled architectures only support the efivarfs pseudo-filesystem. So let's finally rip off the band aid, and drop the old interface entirely. This will make it easier to refactor and clean up the underlying infrastructure that is shared between efivars, efivarfs and efi-pstore, and is long overdue for a makeover.

x86/config: Make the x86 defconfigs a bit more usable

2022-03-27T18:58:35Z

- Use 'make savedefconfig' to refresh & regenerate the files - Add in KVM boot enablers - Enable the cgroup features most distros rely on [ fix bug found by Nathan Chancellor ] Acked-by: Nathan Chancellor Cc: Linus Torvalds Cc: Borislav Petkov Cc: Thomas Gleixner Cc: Peter Zijlstra Signed-off-by: Ingo Molnar Link: https://lore.kernel.org/r/YjwsUT/6PkRPjnHE@gmail.com

x86/defconfig: Enable WERROR

2022-03-24T08:10:56Z

To quote Linus: "EVERYBODY should have CONFIG_WERROR=y on at least x86-64 and other serious architectures, unless you have some completely random experimental (and broken) compiler. New compiler warnings are not acceptable." So this should make at least the most obvious and common ones not go unnoticed.

x86/kbuild: Enable CONFIG_KALLSYMS_ALL=y in the defconfigs

2022-01-08T21:55:29Z

Most distro kernels have this option enabled, to improve debug output. Lockdep also selects it. Enable this in the defconfig kernel as well, to make it more representative of what people are using on x86. Signed-off-by: Ingo Molnar Link: https://lore.kernel.org/r/YdTn7gssoMVDMgMw@gmail.com

x86/defconfig: Enable CONFIG_LOCALVERSION_AUTO=y in the defconfig

2021-12-30T07:37:54Z

With CONFIG_LOCALVERSION_AUTO=y enabled, 'uname' provides much more useful output on debug kernels: Before: # CONFIG_LOCALVERSION_AUTO is not set $ uname -a Linux localhost 5.16.0-rc7+ #4563 SMP PREEMPT Thu Dec 30 08:28:38 CET 2021 x86_64 GNU/Linux After: # CONFIG_LOCALVERSION_AUTO=y $ uname -a Linux localhost 5.16.0-rc7-02294-g5537f9709b16 #4562 SMP PREEMPT Thu Dec 30 08:27:17 CET 2021 x86_64 GNU/Linux This is particularly valuable during bisection, if we want to double check the exact kernel version we are testing. (Just remove the config line, the global Kconfig default for this is default-y.) Cc: Thomas Gleixner Cc: Borislav Petkov Cc: Dave Hansen Cc: x86@kernel.org Cc: "H.

configs: remove the obsolete CONFIG_INPUT_POLLDEV

2021-09-08T18:50:28Z

This CONFIG option was removed in commit 278b13ce3a89 ("Input: remove input_polled_dev implementation") so there's no point to keep it in defconfigs any longer. Get rid of the leftover for all arches.
