| Subject: [PATCH 2/5] kexec: Add imaxdiv implementation for klibc builds |
| |
| klibc doesn't provide the imaxdiv_t structure or imaxdiv() function |
| from inttypes.h. Add a simple inline implementation when building |
| with klibc. |
| |
| The imaxdiv() function computes the quotient and remainder of the |
| division of numer by denom, which is required for standard C99 |
| compliance but missing in minimal libc implementations. |
| |
| Upstream-Status: Pending |
