Hi ARM SoC Team,

Please pull ! This is the only fix/update I have at the moment for v7.1

  firmware: arm_ffa: Use the correct buffer size during RXTX_MAP (2026-04-07 10:47:42 +0100)

----------------------------------------------------------------
Arm FF-A fix for v7.1

Use the page aligned backing allocation size when computing the RXTX_MAP
page count. This fixes FF-A RX/TX buffer registration on kernels built
with 16K/64K PAGE_SIZE, where alloc_pages_exact() backs the buffer with a
larger aligned span than the discovered minimum buffer size.
