[GIT PULL] EFI fixes for v6.14 #1

[Ard Biesheuvel <ardb+git@google.com>]

From: Ard Biesheuvel <ardb@kernel.org>

Hi Linus,

Please pull the changes below. While not true fixes, these changes are best
merged asap so they can make their way into the stable kernels. That should
ensure that the new EFI_MEMORY_HOT_PLUGGABLE memory attribute is used
consistently by Linux before it ever turns up in production, ensuring that we
can make meaningful use of it without running the risk of regressing existing
users.


The following changes since commit 2014c95afecee3e76ca4a56956a936e23283f05b:

  Linux 6.14-rc1 (2025-02-02 15:39:26 -0800)

  efi: Use BIT_ULL() constants for memory attributes (2025-02-04 14:08:22 +0100)

----------------------------------------------------------------
EFI fixes for v6.14 #1

Take the newly introduced EFI_MEMORY_HOT_PLUGGABLE memory attribute into
account when placing the kernel image in memory at boot. Otherwise, the
presence of the kernel image could prevent such a memory region from
being unplugged at runtime if it was 'cold plugged', i.e., already
plugged in at boot time (and exposed via the EFI memory map)
