Starting with commit 867a6ac86dd8 ("efi: Add start-up library code"),
sparse constantly complains about truncated constant value in efi.h:
include/efi.h:176:35: warning: cast truncates bits from constant value
(8000000000000000 becomes 0)
This can get quite noisy, preventing real issues to be noticed:
$ make defconfig
*** Default configuration is based on 'sandbox_defconfig'
$ make C=2 -j12 2>&1 | grep truncates | wc -l
441
After the patch is applied:
$ make C=2 -j12 2>&1 | grep truncates | wc -l
0
$ sparse --version
v0.5.2
Fixes: 867a6ac86dd8 ("efi: Add start-up library code")
