From: Matt Fleming <[email protected]>
I've got the following patches queued up on my next branch for the
v3.8 merge window. The patches are available at,
git://git.kernel.org/pub/scm/linux/kernel/git/mfleming/efi.git next
The main changes are,
* A new EFI variable filesystem, efivarfs, which addresses the
shortcomings of the old sysfs EFI variable code.
* We now switch to a 1:1 mapped pagetable for all virtual EFI
calls. This is actually a workaround for an ASUS firmware bug
which expects the physical mapping to still be around at
runtime.
* Because of the above fix Jan's patch to use EFI for the platform
wall clock can be re-applied (it was originally reverted because
it broke some ASUS machines).
Andy Whitcroft (5):
efivarfs: efivarfs_file_read ensure we free data in error paths
efivarfs: efivarfs_create() ensure we drop our reference on inode on
error
efivarfs: efivarfs_fill_super() fix inode reference counts
efivarfs: efivarfs_fill_super() ensure we free our temporary name
efivarfs: efivarfs_fill_super() ensure we clean up correctly on error
Jan Beulich (1):
