Subject: x86: apply missing DMA/OOM prevention to floppy_32.h
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2dc27f01ec3990d79fc97386459191fc3da2b02f;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

x86: apply missing DMA/OOM prevention to floppy_32.h

commit 554d284ba90bc2306c31e5363789f05c320969c3 added _GPF_NORETRY
to floppy_64.h to prevent OOM killer on floppy DMA allocations.

Apply the same to the 32 bit variant.

Found during the attempt to unify the _32/_64 variants. Seperate commit
to document the resulting code change.
