Subject: [PATCH 0/4] i386 GDT cleanups
Date: Wed, 21 Mar 2007 17:30:36 +1100 [thread overview]
Message-ID: <1174458636.11680.143.camel@localhost.localdomain> (raw)
In-Reply-To: <1174457426.11680.132.camel@localhost.localdomain>
After lots of good feedback and contributions from the last series, this
set of 4 simply cleans up GDT usage in i386. Percpu->pda is not
included: it's really a separate problem (but made much simpler by these
patches).
Patches are:
no-gdt-pda-alloc.patch
- Simplify by using per-cpu vars for gdt & pda, not allocating.
This patch has been seen here before, and Jeremy Fitzhardinge
acked it.
direct-percpu-gdt.patch
- Simplify boot by switching straight from boot_gdt_table
straight to per-cpu versions, rather than going to cpu_gdt_table
then per-cpu gdt. This is a new approach after Ingo cautioned
about removing boot_gdt_table.
cleanup-cpuinits.patch
- Simple patch: we can now roll two identical functions together
cleanup-gdt-accessors.patch
- Remove a level of indirection
Cheers,
Rusty.
