efivars: Move pstore code into the new EFI directory efivars.c has grown far too large and needs to be divided up. Create a new directory and move the persistence storage code to efi-pstore.c now that it uses the new efivar API. This helps us to greatly reduce the size of efivars.c and paves the way for moving other code out of efivars.c. Note that because CONFIG_EFI_VARS can be built as a module efi-pstore must also include support for building as a module.

efi/reboot: Add generic wrapper around EfiResetSystem() Implement efi_reboot(), which is really just a wrapper around the EfiResetSystem() EFI runtime service, but it does at least allow us to funnel all callers through a single location. It also simplifies the callsites since users no longer need to check to see whether EFI_RUNTIME_SERVICES are enabled.

efi: split efisubsystem from efivars This registers /sys/firmware/efi/{,systab,efivars/} whenever EFI is enabled and the system is booted with EFI. This allows *) userspace to check for the existence of /sys/firmware/efi as a way to determine whether or it is running on an EFI system. *) 'mount -t efivarfs none /sys/firmware/efi/efivars' without manually loading any modules. [ Also, move the efivar API into vars.c and unconditionally compile it. This allows us to move efivars.c, which now only contains the sysfs variable code, into the firmware/efi directory. Note that the efivars.c filename is kept to maintain backwards compatability with the old efivars.ko module. With this patch it is now possible for efivarfs to be built without CONFIG_EFI_VARS - Matt ] Cc: Seiji Aguchi <seiji.aguchi@hds.com> Cc: Tony Luck <tony.luck@intel.com> Cc: Mike Waychison <mikew@google.com> Cc: Kay Sievers <kay@vrfy.org> Cc: Jeremy Kerr <jk@ozlabs.org> Cc: Matthew Garrett <mjg59@srcf.ucam.org> Cc: Chun-Yi Lee <jlee@suse.com> Cc: Andy Whitcroft <apw@canonical.com> Cc: Tobias Powalowski <tpowa@archlinux.org> Signed-off-by: Tom Gundersen <teg@jklm.no> Signed-off-by: Matt Fleming <matt.fleming@intel.com>

Move cper.c from drivers/acpi/apei to drivers/firmware/efi cper.c contains code to decode and print "Common Platform Error Records". Originally added under drivers/acpi/apei because the only user was in that same directory - but now we have another consumer, and we shouldn't have to force CONFIG_ACPI_APEI get access to this code. Since CPER is defined in the UEFI specification - the logical home for this code is under drivers/firmware/efi/ Acked-by: Matt Fleming <matt.fleming@intel.com> Acked-by: Ingo Molnar <mingo@kernel.org> Signed-off-by: Tony Luck <tony.luck@intel.com>

Revert "efi/x86: efistub: Move shared dependencies to <asm/efi.h>" This reverts commit f23cf8bd5c1f ("efi/x86: efistub: Move shared dependencies to <asm/efi.h>") as well as the x86 parts of commit f4f75ad5741f ("efi: efistub: Convert into static library"). The road leading to these two reverts is long and winding. The above two commits were merged during the v3.17 merge window and turned the common EFI boot stub code into a static library. This necessitated making some symbols global in the x86 boot stub which introduced new entries into the early boot GOT. The problem was that we weren't fixing up the newly created GOT entries before invoking the EFI boot stub, which sometimes resulted in hangs or resets. This failure was reported by Maarten on his Macbook pro. The proposed fix was commit 9cb0e394234d ("x86/efi: Fixup GOT in all boot code paths"). However, that caused issues for Linus when booting his Sony Vaio Pro 11. It was subsequently reverted in commit f3670394c29f. So that leaves us back with Maarten's Macbook pro not booting. At this stage in the release cycle the least risky option is to revert the x86 EFI boot stub to the pre-merge window code structure where we explicitly #include efi-stub-helper.c instead of linking with the static library. The arm64 code remains unaffected. We can take another swing at the x86 parts for v3.18.
