Peter Maydell 63c1b7de0a linux-user: Report AArch64 hwcap2 fields above bit 31
The AArch64 ELF hwcap2 field is 64 bits, but our get_elf_hwcap2()
works with uint32_t, so it accidentally fails to report any hwcaps
over bit 31.  Use uint64_t here.

The Arm hwcap2 is only 32 bits (because the ELF format makes these
fields be the size of "long" in the ABI), but since it shares the
prototype declaration for get_elf_hwcap2() it is easier to also
expand it to 64 bits.

The only hwcap fields we implement already that are affected by this
are the HBC and MOPS ones, neither of which were implemented in a
previous release, so this doesn't need backporting to older stable
branches.

Richard Henderson d0b6b79323 linux-user: Replace bprm->fd with bprm->src.fd
There are only a couple of uses of bprm->fd remaining.
Migrate to the other field.

Richard Henderson 7d2c5526ed linux-user: Introduce imgsrc_read, imgsrc_read_alloc
Introduced and initialized, but not yet really used.
These will tidy the current tests vs BPRM_BUF_SIZE.

Helge Deller a55b9e7226 linux-user: Emulate /proc/cpuinfo on aarch64 and arm
Add emulation for /proc/cpuinfo for arm architecture.
The output below mimics output as seen on debian porterboxes.
