How to regenerate vmlinuz-linux

This is the file in /efi used by my UEFI to boot (I use EFISTUB). During the latest kernel update it did not get updated, and now I can't boot. How do I regenerate it (I use dracut not mkinitcpio) ? How did it even get generated in the first place ?

Thanks.

Re: How to regenerate vmlinuz-linux

Re-install the kernel.
You can boot the install iso, mount root partition, boot partition and esp into location, arch-chroot and just "pacman -S linux"
The file reside in /usr/lib/modules/* and gets copied into location by an install hook.
You could copy it manually, but there's a chance it's not in that location either or damaged.

To check the installation integrity

sudo LC_ALL=C pacman -Qkk | grep -v ', 0 altered files' | grep -v 'backup'
