Subject: [PATCH] linux-user: Provide print_raw_param64() for 64-bit values
Date: Tue, 31 Jan 2023 18:18:36 +0100	[thread overview]
Message-ID: <Y9lNbFNyRSUhhrHa@p100> (raw)

Add a new function print_raw_param64() to print 64-bit values in the
same way as print_raw_param(). This prevents that qemu_log() is used to
work around the problem that print_raw_param() can only print 32-bit
values when compiled for 32-bit targets.

Additionally convert the existing 64-bit users in print_timespec64(),
print_rlimit64() and print_preadwrite64() over to this new function and
drop some unneccessary spaces.
